Products/Services for linear control valve
Valve positioners compare a control signal to a valve actuator’s position and move the actuator accordingly. They are used with both linear valves and rotary valves. Search by Specification | Learn More about Valve Positioners
Electrohydraulic valve actuators and hydraulic valve actuators convert fluid pressure supply pressure into motion. Search by Specification | Learn More about Electrohydraulic Valve Actuators and Hydraulic Valve Actuators
Pneumatic valve actuators adjust valve position by converting air pressure into linear or rotary motion. Search by Specification | Learn More about Pneumatic Valve Actuators
Valve actuators mount on valves and, in response to a signal, move a valve to a desired position using an outside power source. Search by Specification | Learn More about Valve Actuators
Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system. Search by Specification | Learn More about Control Valves
...can be configured in-line or at right angles. In an in-line configuration the input and output ports are on the same axis. In a right angle configuration the input and output ports are perpendicular. Flow control choices for air valves include... Search by Specification | Learn More about Air Valves
Gas valves are used to handle and control the flow of gaseous media such as liquefied petroleum and natural gas. They are made of metal or plastic and vary in terms of valve size, pressure rating, number of ports, and flow. Search by Specification | Learn More about Gas Valves
Electric valve actuators mount on valves which, in response to a signal, automatically move to a desired position using an outside power source. Single-phase or three-phase AC or DC motors drive a combination of gears to generate the desired torque Search by Specification | Learn More about Electric Valve Actuators
Solenoid valves are devices that use a solenoid to control valve activation. Search by Specification | Learn More about Solenoid Valves
Globe valves are linear motion valves with rounded bodies, from which their name is derived. They are widely used in industry to regulate fluid flow in both on/off and throttling service. Search by Specification | Learn More about Globe Valves
Manual valve actuators do not require an outside power source. They use a handwheel or lever to drive a series of gears whose ratio results in a higher output torque compared to the input (manual) torque. Search by Specification | Learn More about Manual Valve Actuators
Sanitary valves are designed for applications requiring clean or sterile processing. Search by Specification | Learn More about Sanitary Valves
Motion control systems contain matched components such as controllers, motor drives, motors, encoders, user interfaces and software. Components in these systems are optimally matched by the manufacturer. Search by Specification | Learn More about Motion Control Systems
Vacuum valves are used when a vacuum must be maintained in a closed system. Search by Specification | Learn More about Vacuum Valves
Electric linear actuators have an output rod that provides linear motion via a motor driven ball screw, lead screw, or ACME screw assembly. The actuator's load is attached to the end of a screw or rod and is often Search by Specification | Learn More about Linear Actuators
