Excess flow valve

An excess flow valve (10) includes: a valve (12) that opens and closes a flow path (11); a solenoid (14) that keeps the valve (12) in an opened state; a pressure detector (16) detecting the primary-side pressure of the valve (12); and a controller (17) controlling current flow to the solenoid (14) b...

More Information
Summary:An excess flow valve (10) includes: a valve (12) that opens and closes a flow path (11); a solenoid (14) that keeps the valve (12) in an opened state; a pressure detector (16) detecting the primary-side pressure of the valve (12); and a controller (17) controlling current flow to the solenoid (14) based on pressure detected by the pressure detector (16) so that the valve (12) is closed when the flow rate supplied to the valve (12) is at or more than a predetermined amount. The excess flow valve (10) can be used in a wide variety of applications and prevents a flow of fluid at or greater than a desired flow rate even if the primary-side supply pressure varies.
