Primary Material of Construction




   Metals       
   Your choices are...
 
      
 
   Aluminum
 
     Aluminum is a bluish silver-white malleable ductile light trivalent metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
 
   Brass / Bronze
 
     Brass comes with good strength, excellent high temperature ductility and reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties and low magnetic permeability.  Sintered bronze is a porous material, which can be impregnated with oil, graphite or PTFE. Not suitable for heavily loaded applications but useful where lubrication is inconvenient.
 
   Cast Iron
 
     The term "cast iron" refers not to a single material, but to a family of materials whose major constituent is iron, with important trace amounts of carbon and silicon. Cast irons are natural composite materials whose properties are determined by their microstructures - the stable and metastable phases formed during solidification or subsequent heat treatment. The major microstructural constituents of cast irons are: the chemical and morphological forms taken by carbon, and the continuous metal matrix in which the carbon and/or carbide are dispersed.
 
   Ductile Iron
 
     Ductile iron retains cast iron's machinability and corrosion-resistance, and provides additional strength, toughness, and ductility. Although it’s chemical properties are similar to those of cast iron, ductile iron incorporates significant casting refinements, additional metallurgical processes, and superior quality control.
 
   Copper
 
     A common reddish metallic element that is ductile and malleable and is one of the best conductors of heat and electricity.
 
   Stainless Steel
 
     Stainless steel is chemical and corrosion resistant and can have relatively high-pressure ratings.
 
   Steel
 
     Steel is a commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content.
 
   Other Metal
 
     Other unlisted, specialized, or proprietary metal material.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Plastics:      Please consult the manufacturer of the valve for specific properties of the materials used in the valve.
   Your choices are...
 
      
 
   Acetal
 
     Acetal polymers are semi-crystalline. They offer excellent inherent lubricity, fatigue resistance, and chemical resistance. Acetals suffer from outgassing problems at elevated temperatures, and are brittle at low temperatures. Glass filled, and added lubrication grades are available, flame-retardant grades are not. Brand names include Celcon® (Hoechst Celanese), Delrin® (Dupont), Thermocomp® (LNP), Ultraform® (BASF), and Acetron® (DSM).
 
   PVC
 
     Polyvinyl Chloride (PVC) is a widely used material that has good flexibility, smooth surface, and nontoxic qualities. Some grades are used in food and chemical processes due to the inert nature of PVC. Brand names include: ACP® and Dural® (Alpha Gary), Geon® (Geon), Benvic® (Solvay), Flexalloy® (Teknor Apex).
 
   CPVC
 
     Chlorinated polyvinyl chloride (CPC) a higher type grade of plastic commonly used for hot / cold water distribution, sprinkler piping, and some chemicals. Suitable for high temperatures.
 
   PTFE - Teflon®
 
     Polytetrafluoroethylene (PTFE) is an insoluble compound that exhibits a high degree of chemical resistance and a low coefficient of friction. It is sometimes marketed in proprietary classes of materials such as Teflon®, a registered trademark of DuPont Dow Elastomers.
 
   Polyethylene (PE)
 
     Commodity thermoplastic that is soft, flexible and tough - even at low temperatures - with outstanding electrical properties but poor temperature resistance. It also has very good chemical resistance but is prone to environmental stress cracking; it has poor UV resistance (unless modified) and poor barrier properties, except to water.
 
   Polypropylene (PP)
 
     Polypropylene is a thermoplastic material exhibiting excellent cold flow, bi-axial strength, and yield elongation properties. It is similar to PVC but can be used in exposed applications because of its resistance to UV, weathering, and ozone.
 
   PVDF
 
     Polyvinylidene fluoride (PVDF) is a melt processable fluoropolymer. It is similar in properties to other fluoropolymer, but has better strength and lower creep than the other members of this family. PVDF has good wear resistance, and excellent chemical resistance. But does not perform well at elevated temperatures. Brand names include: Kynar® (Elf AtoChem).

Valve Type




   By Technology       
   Your choices are...
 
      
 
   Angle Valves
 
     Angle valves have an inlet and outlet at 90 degrees, or a control mechanism that enters the valve body at an angle to conserve room and allow maximum flow.
 
   Ball Valves
 
     Ball valves provide tight shut-off and characterizable control. They have high rangeability due to the design of the regulating element, without the complications of side loads typical of butterfly or globe valves. Advantages include ease of operation and high flow, high pressure, and high temperature capabilities. Disadvantages include low cleanliness and an inability to handle slurries.
 
   Bellows Valves
 
     Bellows valves have a bellows seal between the media and the valve's bonnet. Bellows valves provide a contaminant-free, positive shut-off for high purity gas / fluid systems.
 
   Butterfly Valves
 
     Butterfly valves control the flow of gas or liquid with a disk which turns on a diametrical axis inside a pipe, or by two semicircular plates hinged on a common spindle, permitting flow in only one direction. They are used as throttling valves to control flow. Butterfly valves offer a rotary stem movement of 90 degrees or less in a compact design.  Unlike ball valves, butterfly valves do not have pockets in which fluids may become trapped when the valve is closed. Advantages include suitability for chemical services, small dimensions, and high coefficient of flow.
Disadvantages include low cleanliness and the inability to handle slurries.
 
   Cartridge / Manifold Valves
 
     Cartridge valves are directional control valves that are inserted into manifolds to provide a cost effective compact system design.
 
   Check Valves
 
     Check valves are self-activating safety valves that prevent process flow from reversing.
 
   Diaphragm Valves
 
     Diaphragm valves are related to pinch valves, but use an elastomeric diaphragm instead of an elastomeric liner to separate the flow stream from the closure element. Instead of pinching the liner closed to provide shut-off, the diaphragm is pushed into contact with the bottom of the valve body.  Diaphragm valves are excellent for controlling the flow of fluids which contain suspended solids. They also offer the flexibility of installation in any position. Diaphragm valves are used widely in the pharmaceutical, food processing, and water treatment industries. Advantages include cleanliness and tight shut-off. Disadvantages include low pressure and temperature limits, and multi-turn operation.
 
   Gate / Knife Valves
 
     Gate or knife valves are linear motion valves in which a flat closure element slides into the flow stream to provide shut-off. Gate valves are usually divided into two types: parallel and wedge-shaped. The parallel gate valve uses a flat disc gate between two parallel seats, upstream and downstream. Knife valves are of this type, but with a sharp edge on the bottom of the gate to shear entrained solids or separate slurries. Advantages include the ability to cut through slurries. Large sizes are commonly available. Disadvantages include pressure limitations,
lack of cleanliness, and low shut-off.
 
   Globe Valves
 
     Globe valves are linear motion valves with rounded bodies, from which their name is derived.  They are used widely in industry to regulate fluid flow in both on/off and throttling service.  Advantages include precise throttling and control, as well as high-pressure limits. Disadvantages include low cleanliness and the inability to handle slurry.
 
   Needle Valves
 
     Needle valves have a slender, tapered point at the end of the valve stem that is lowered through the seat to restrict or block flow.  Fluid flowing through the valve turns 90 degrees and passes through an orifice that is the seat for a rod with a cone shaped tip. These small valves are widely used to accurately regulate the flow of liquids and gases at low flow rates. The fine threading of the stem and the large seat area allow for precise resistance to flow. Advantages: Precise control. Disadvantages: low-pressure limitations, no slurries.
 
   Pinch Valves
 
     Pinch valves include any valve with a flexible elastomer body that can be pinched closed, cutting off flow, using a mechanism or fluid pressure. Pinch valves are full bore, linear action valves so they can be used in both an off/on manner or in a variable position or throttling service. Some typical applications for pinch valves are medical, pharmaceutical, wastewater, slurries, pulp, powder and pellets. They can effectively control the flow of both abrasives and corrosives, as there is no contact between metal parts and the transport media.
Advantages: Streamlined flow, high coefficient of flow. Disadvantages: limited materials, low shut-off capabilities, low pressure limits.
 
   Plug Valves
 
     Plug valves, also called cock or stop-cock valves, date back to ancient times, where they were developed for use in citywide Roman plumbing systems. Today, they remain one of the most widely used valves for both on/off and throttling services.  Their design is fairly simple; the body is comprised of three main parts: body, cover and plug.  The plug is a cylindrical, tapered, or generally cone-shaped device that can be raised or lowered within the seat to maintain, restrict or completely shut off flow.  The valve is opened by rotation with the plug itself being the only element that is capable of movement. Advantages: Easy operation, medium to high flow, good shut off. Disadvantages: Low cleanliness, inability to handle slurry.
 
   Poppet Valves
 
     Poppet valves open and close ports with a sealing device composed of a disk, cone or sphere that is pressed against the seating surface using a spring.
 
   Regulators
 
     Regulators maintain a constant outlet pressure.
 
   Servo Valves
 
     Servo valves provide closed loop flow or pressure response to an electrical or electronic control signal. They are used in air, gas, and liquid applications.
 
   Solenoid Valves
 
     Solenoid valves are electro-mechanical devices that utilize a solenoid to control valve activation.
 
   Spool Valves
 
     Spool valves use a rotary or piston-like spool for actuation. The spool, or spools, rotate or slide back and forth to block and uncover ports in the housing.
 
   Toggle Valves
 
     Toggle valves are used for on-off control in moderate pressure and temperature applications. They feature a toggle mechanism for valve actuation.
 
   Other
 
     Other unlisted valve technology.

   By Application       
   Your choices are...
 
      
 
   Balancing Valves
 
     Balancing valves are mixing valves that maintain a constant water temperature by balancing hot and cold supply lines. They are able to compensate for a pressure drop in either supply line and can maintain a consistent temperature. Balancing valves are sometimes referred to as pressure-balancing valves.
 
   Float Valves
 
     Float valves automatically open or close as the level of a fluid changes. A float that rests on the top of the liquid operates these valves mechanically.
 
   Drain Valves
 
     Drain valves allow the removal of surplus fluid from a system or container.
 
   Diverter Valves
 
     Diverter valves change the direction of the flow of a medium to two or more different directions.
 
   Directional Valves
 
     Directional valves direct or prevent flow through selected passages.
 
   Mixing Valves
 
     Mixing valves combine the flows of two or more inlets into a single outlet for applications such as temperature or concentration control.
 
   Metering Valves
 
     Metering valves are capable of accurately controlling the flow of a fluid.
 
   Pressure Relief Valves
 
     Pressure relief valves are self-actuated safety valves designed to relieve excess upstream pressure from the line.
 
   Safety Valves
 
     Safety valves contain a thermal sensing component that opens or closes in response to temperature changes or close a line and stop the flow of material when a pre-set condition occurs.
 
   Sampling / Dispensing Valves
 
     Sampling valves or dispensing valves are fitted to a reactor or pipeline to allow a small sample of a fluid to be withdrawn for testing or mixing. Some sampling valves ‘trap’ a small quantity of fluid in a chamber, and only this fluid is released when the valve is operated.
 
   Sanitary / Hygienic Valves
 
     Sanitary and hygienic valves are used in aseptic applications in the dairy, brewing, beverage, pharmaceutical and bio-chemical industries.
 
   Shut Off Valves
 
     Shut off valves close a line to stop the flow of material when a pre-set condition occurs such as excess flow or a pressure pulse from a broken line or a temperature change from an idle burner.
 
   Underwater Valves
 
     Underwater valves are designed to handle excess external pressure and block water ingress in underwater applications. For example, they may be installed in a pipeline on the seabed.  Underwater valves are also referred to as sub-sea valves.
 
   Vacuum Relief / Anti-siphon Valves
 
     Vacuum relief valves are automatic valves that open or close a vent to relieve a vacuum, depending on whether the vacuum is above or below a predetermined value. They are frequently used in hot water supply systems.

An anti-siphon valve is a valve, usually plastic or brass, used to control the flow of water in one direction. It will prevent a backflow of water into the potable water supply.
