Abstract: An excess flow control valve for telescopical receipt in a cylindrical fluid distribution pipe to control downstream flow therein. The excess flow valve includes a cylindrical pressure reducer fitting for mounting the valve in the pipe and is formed with an upstream facing annular valve seat and a downstream diverging venturi nozzle therethrough. A poppet valve barrel having a central chamber is mounted to the pressure reducer fitting, the chamber formed with a plurality of peripheral inlet flow passages disposed upstream of the fitting and further including at the upstream end thereof, a gland. A poppet having an cylindrical base and an upstream projecting stem is slidably received in the chamber and the stem is received in the gland. The stem includes a stop ring at the upstream end thereof and a compression spring is disposed over the stem in an interposed relationship between the valve barrel and the stop ring to bias the poppet away from the valve seat.
