ABSTRACT:
A hydraulic valve for controlling the flow of a pressured liquid with a housing that has an inlet and an outlet with a pivotally mounted handle that actuated a valve stem member housed within an internal bore with a counter bore step surface. An O-ring member is mounted on the step surface that comes in contact with a convex surface provided in a peripheral flange member on the stem member. A compressible cylindrical member is trapped partially within an opening at one end of the valve stem member urging the convex surface against the O-ring thus blocking the flow of the pressurized liquid through the internal valve bore.
