Safety Relief Valve RMG 832 Design and operation

This safety relief valve (SBV) was designed to automatically relieve a gas stream from a pressure bearing line, as soon as the pressure prevailing in the system to be protected rises up to the pre-set response pressure limit. The SBV will close again, after this pressure will have fallen below the closing pressure limit. The RMG 832 is a spring-loaded, direct acting safety relief valve (without auxiliary energy from the inlet pressure). The valve is available in two versions: as a relief valve (SBV) for gas leakages, and as a main safety device. If it is used as a relief valve for gas leakages, provision is made for internal venting of the spring housing. If the valve is used as a main safety device, its spring housing is provided with a connecting piece for a separate external vent line. The pressure to be monitored is conveyed to the measuring diaphragm through the inlet connection and compared to the force given by the pre-adjusted setpoint spring. If the pressure within the system to be protected rises above the pre-set response pressure, the valve opens and allows the gas to escape through the outlet line. The relief valve will close automatically, as soon as the pressure prevailing in the system to be protected will have fallen below the response pressure level. The piston of the control element is relieved and balanced by a pressure spring protecting the valve sealing from stress and premature wear. The measuring diaphragm is designed as a preformed diaphragm which guarantees a high response accuracy, even if the valve is exposed to low ambient temperatures. The setpoint spring is guided by a metal sleeve bearing to absorb its lateral forces.
