pressure reduces the seating force to zero and opens the main valve seat to allow flow. The opening of the main valve responds gradually and propor - tionally to the rise in system pressure, either at or above the set pressure. The main valve will achieve full open and rated flow by 10% overpressure. Re-Closing Cycle
This pressure relief valve is designed to protect equipment from overpressure. The valve should be handled with care, not subjected to heavy shock loads and protected to prevent contamination from getting inside. It should be installed correctly per ASME boiler and pressure vessel code requirements, where applicable.
Relief and Sequence Valves Pressure relief valves mount between the pump and valve system to protect against overloads. A suitable pilot valve may be used to “vent” the balanced piston relief valve when the system does not require power. This venting unloads the pump through the relief valve at low pressure, avoiding energy waste and
Cost-effective 1/4 NPT—2 NPT. Commercially available to handle large variety of temperatures and pressures. Set pressure affected by superimposed back pressure at a 1:1 ratio. safety relief valve consisting of a main valve assembly and a controlling pilot valve, combined in one stand-alone unit.
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.
Each relief valve incorporates a vent port that can be connected to a separate pilot control valve to remotely control or unload system pressure. Two types of valve are presented in this catalog: CG2V-***, 10 series: relief/sequence valve with integral manual adjustment of pressure setting. CG5V-***, 11 series: relief valve with
