Detailed Diaphragm Type Pressure Relieving / Sustaining Valve Description
Diaphragm type adyustable pressure reducing / sustaining valve is installed in feeding
water system pipline in high building, fire protection and other.
The valve can provide and unchanged setting pressure and once the pressure is
over, the valve opens quickly and relieve the over pressure. When the
line pressure is beyond the valve's setting pressure, the valve automatically opens
to relive pressure to ensure the pipline is safe, and at the same time it can
be used as pressure sustaining valve to ensure the upstream prssure is enough. The valve can close
stably and smoothly and prevent the pressure repercussions.
