pilot operated check valve

PORV are also called pilot-operated safety valve (POSV), pilot-operated pressure relief valve (POPRV), or pilot-operated safety relief valve (POSRV), depending on the manufacturer and the application. Technically POPRV is the most generic term, but PORV is often used generically (as in this article) even though it should refer to valves in

Hydraulic pilot operated check valves are simply check valves which can be opened by an external pilot pressure. These designs of hydraulic valve are often 

A test circuit built to check the characteristics of a pilot-operated check valve. The valve is loaded with three ideal pressure sources, two of which create pressure differential across the main flow line, while the third applies pressure to the pilot inlet X. The pilot pressure allows flow through the valve even if the main pressure

The Pilot-Operated Check Valve (TL) block models a check valve with an override mechanism to allow for backflow when activated.

Pilot-Operated Check Valve Test Rig Copy Command This example shows a test circuit built to check the characteristics of a pilot-operated check valve. The valve is loaded with three ideal pressure sources, two of which create pressure differential across the main flow line, while the third applies pressure to the pilot inlet X.

Description. The Pilot-Operated Check Valve (G) block represents a check valve with an override mechanism that allows backflow when activated. A check valve is an orifice with a unidirectional opening mechanism that prevents backflow. The X port of the block represents a pilot port that serves as an override mechanism. During normal operation, the pilot port is inactive and the valve behaves

Pilot-operated check valves. Our pilot-operated check valves are leak-proof check valves with which the flow direction from B to A is open and the flow direction from A to B is normally blocked. If a hydraulic control pressure is applied to connection X, the pilot-operated check valve can be unlocked whereby the flow from A to B will also be
