☆ Bellows Pressure Reducing Valve Product Overview Bellows pressure reducing valve is mainly composed of bellows, adjusting spring, valve seat, valve flap and other components. The direct acting bellows pressure reducing valve utilizes the bellows sensing valve to pressure-actuate the valve disc and change And control the valve opening to achieve vacuum regulator function. Set the outlet pressure by adjusting the adjusting screw. Bellows relief valve main technical parameters Nominal pressure (MPa) 0.6 1.0 1.6 Shell test pressure (MPa) 0.9 1.5 2.4 Sealing test pressure (MPa) 0.6 1.0 1.6 The maximum inlet pressure (MPa) 0.6 1.0 1.6 The outlet pressure range (MPa) 0.05-0.4 0.1-0.8 0.1-1.0 Pressure characteristic deviation (MPa) △ P2P GB12244-1989 Flow characteristic deviation (MPa) △ P2G GB12244-1989 Minimum pressure difference (MPa) 0.1 0.15 0.15 Leakage amount GB12245-1989 *: Housing Test does not include bellows, shell pressure test, the bellows assembly must be removed after.
