Emergency Shut-off Valves (ESV)

Emergency shut-off valves (ESV) automatically close in the event of an emergency to prevent the loss of handled media. Emergency shut-off valves (ESV) are installed on fuel lines, steam and hot water pipes, vapor lines, and hoses carrying caustic or hazardous liquids and gases.

Emergency shut-off valves (ESV) are frequently installed on residential water and gas lines. A water shut off valve ensures that if there is a pipe leak or burst pipe somewhere in the house, the water supply to the pipe can be shut off at the source to minimize damage. Homes that are served by a well typically have an emergency shut-off valve outside to cut off the supply to the entire house. Homes heated with natural gas usually have a gas shut off valve located near the gas meter or gas service pipe coming into the house. Appliances such as a hot water heater or oven may also have a gas valve to shut off the supply.

Emergency shut-off valves(ESV) are vital safety components of any fuel-based system or manufacturing process that uses liquid or gas media in production. Emergency shut-off valves (ESV) are used in engines to cut off the supply of fuel and shut down the engine. Diesel engines may also use an air intake emergency shut off valve since a diesel engine can continue to run for a short period of time on hydrocarbon fumes even when the fuel supply is cut off. A fuel shut off valve is also commonly used in a gas pump to shut off the flow of gas when the car’s tank is full.

Emergency shut-off valves (ESV) used in industrial processing applications can be electromechanical or electropneumatic and can respond quickly to a variety of processing parameters such as flow rate, temperature, and pressure. Emergency shut off valves (ESV) are typically calibrated for a particular media, such as the type of gas or liquid being used.
