Pressure Relief Valve (PRV) A pressure relief device designed to actuate on inlet static pressure and to reclose after normal conditions have been restored. It may be one of the following types and have one or more of the following design features. A. Restricted lift PRV: a pressure relief valve in which the actual
It contains technical information on pressure relief valves and devices. The handbook has 8 chapters that cover terminology, codes and standards, design fundamentals, valve sizing and selection, and engineering support information.
1) If valves with onboard electronics are used in safety-related parts of control systems, in case the safety function is requested, the valve electronics voltage supply is to be switched off by a suitable switching element with suficient reliability. Signal flow diagram. 2. Safety Instructions.
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.
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
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.
