Product Detail

Product Tags

▪ Reliable pressure reducing function: The outlet pressure is not affected by the change of inlet pressure and flow, which can reduce both dynamic pressure and static pressure.
▪ Easy adjustment and operation: Just adjust the adjusting screw of the pilot valve to obtain accurate and stable outlet pressure.
▪ Good energy saving: It adopts semi-linear flow channel, wide valve body and equal flow cross-sectional area design, with small resistance loss.
▪ Main spare parts are made of special materials and basically do not need maintenance.

▪ Test pressure:
Shell Test Pressure 1.5 x PN
Seal Test Pressure 1.1 x PN
