A poultry watering valve (10) includes a housing (12) including a body (18) and cap (20) defining a chamber (22) with a valve seat (36) at its upstream end. A unitary seal member (56) in the chamber includes a valve member portion (82) urged by a spring (58) against the downstream side of the valve seat (36). The seal member (56) also includes a restrictor pin (84) and a shank (66) carrying an operating stem (60) extending through the valve outlet (16). The cap (20) may be detached from the body (18) for access to the seal member (56) and spring (58) without removing the body from the water supply conduit.
