Pressure relief valve type CG2V The pressure present in port P acts on the main spool (3). At the same time pressure is applied via the control lines (6) and (7), which are ˜tted with ori˜ces (4) and (5), on the spring loaded side of the main spool (3) and at the ball (8) in the pilot control valve (2). If the pressure in port P exceeds the ...
pressure relief valves. They are used for limitation (DB) or limitation and solenoid-actuated unloading (DBW) of the operating pressure. The pressure relief valves (DB) basically consist of the main valve (1) with main spool insert (3) and pilot control valve (2) with pressure adjustment element.
Relieve pressure in the system before removing hoses, fittings, gauges, or components. Never use your hand or any other body part to check for leaks in a pressurized line.
It provides equations, tables, and guidance to help with the proper application and sizing of pressure relief valves. The handbook is a technical reference for engineers working with pressure relief valves.
