It has one pressure port (P,1), two ports (A,2) and (B,4) that connect to the device that needs to be controlled, and two exhaust ports (EA,3) and (EB,5). Heres how to test and replace a pressure relief valve. Pressure relief valve (PRV) or Pressure Release valve (PRV) or pressure safety valve (PSV): The difference is that PSVs have a manual lever to activate the valve in case of emergency. Control Valve Actuators Pressure Switch Pneumatic actuators use air pressure pushing against either a flexible diaphragm or a piston to move a Ideally, the safety valve will deploy if the pressure in your tank gets too high. Home Page: The Annals of Thoracic Surgery Vent Relief Valve Pressure unit: The pressure measure unit for the bourdon tube pressure gauge is bar or psi.
