Abstract

An improved trap primer valve may include a valve body having a central tube having a proximal end coupled to an outlet orifice and an open distal end extending into a longitudinal bore of the valve, such that fluid exiting the outlet orifice passes through the central tube. A plug, including a head portion and a rod extending from the head portion into the central tube, may be configured to selectively seat against the distal end of the central tube. An annular cartridge surrounding the central tube may have one or more apertures leading to a partially water-filled inner chamber, and may be configured to unseat the plug in automatic response to a fluctuation in system water pressure, thereby opening the valve and charging a downstream trap.

Abstract

A flow meter trap primer valve assembly for regulating flow includes an inlet for receiving water from a supply, a check valve mounted within an adaptor having an elongate bore forming a jet, and the check valve includes a piston mounted within a cartridge. A biasing element normally urges the piston against a trap seat.
