A poultry watering valve includes a housing including a body and cap defining a recess with a valve seat at its upstream end. A unitary seal member in the chamber includes a valve member portion urged by a spring against the downstream side of the valve seat. The seal member also includes a restrictor pin extending in an inlet bore upstream from the valve seat and a shank carring an operating stem setending through the valve outlet. The cap may be detached from the body for access to the seal member and spring without removing the body from the water supply conduit. |
