<p>A fluid valve for use in a two handle faucet assembly has a housing, a sleeve within the housing, a stem positioned within the sleeve with a handle portion extending outside of the sleeve and housing, and a reciprocal piston. Rotation of the stem causes reciprocation of the piston. A grommet-type seal is attached to the interior end of the sleeve, adjacent its inlet, and has a portion extending within the sleeve toward the axially movable piston. The seal portion extends in the direction of fluid flow through the valve with the piston closing against the direction of fluid flow onto the extending portion of the seal to effect opening and closing of the valve.</p> |
