<p>A straight flow seat valve, comprising, a valve housing with a valve chamber therein having an inlet at one end and an outlet at the opposite end which is coaxial with the inlet. A control cylinder is supported in the valve chamber between the outlet and inlet and has a control fluid inlet extending out of the housing for the admission of a control fluid into the chamber in order to move a piston against a spring-biasing force so as to shift a seat body having a seat surface in engagement with a seat adjacent the outlet end so that it is lifted off the seat to open the valve. The seat body is advantageously streamlined at each end to permit flow around it from the inlet around the valve and out through the outlet. In the pressureless state, the spring urges the surface of the seat body onto the valve seat to close the valve.</p> |
