Product Description
Pressure Sustaining / Swift pressure relief/ Emergency Open Valve
MODEL NO.: GL500X
Δ Pressure relief valve: This valve releases pressure from the pipeline when the pressure is higher than a preset data by the pilot. It keeps the pressure in pipeline safely below a certain value and protects pipeline equipment from damage due to high pressure or sudden pressure wave.
This model can be used to release pressure for fire protection testing recycling system in high building and protect system from danger of high pressure.
Δ Pressure Sustaining/holding valve: This valve also functions to keep upper stream pressure higher than a preset data by the pilot so as to secure the upper stream water supply pressure.
Emergency Open Valve: This valve can be mounted at the outlet port of fire spraying pump. It will immediately open when the pressure at pump outlet port is higher than a preset value.
Pressure rating: PN10, PN16, PN25, PN40 , CL150, CL300
Size : DN50-DN800
Other options for pressure relief valve:
