Patent abstract
An excess flow valve includes: a valve that opens and closes a flow path; a solenoid that keeps the valve in an opened state; a pressure detector detecting the primary-side pressure of the valve; and a controller controlling current flow to the solenoid based on pressure detected by the pressure detector so that the valve is closed when the flow rate supplied to the valve is at or more than a predetermined amount. The excess flow valve 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.
