A manifold valve is an essential component of pressure and differential pressure transducers. The main function of a manifold valve is to block or isolate the fluid flow to isolate process media from pressure instrumentation. The inclusion of a valve manifold in a tool helps it to be replaced or calibrated without requiring a shutdown.

Oct 31, · A pressure relief valve (PRV), also called a relief valve, is a pressure control valve used to regulate or restrict the pressure in a system. The pressure may build-up, which can lead to a process, instrument, or equipment failure. Pressure relief valves make it possible to avoid this disaster. They act as a shield that limits maximum pressure
