‧Pressure relief valve is installed on the outlet pipe of water supply pipeline. It can maintain safe water supply pressure inside the pipe and prevent pipeline and equipment damage caused by accidental escalation in water pressure.

‧When water pump stops functioning or pipeline gate suddenly closes, abnormal pressure forms inside the pipe. As the pressure gets over a certain safety limit, pressure relief valve can open automatically and releases the water pressure above the safety limit, so as to ensure the safety of pipeline and equipment. When the pressure turns back within the safety limit, the pressure relief will close slowly.

Utilization State of Pressure Relief Valve

When water pressure inside the pipeline becomes greater than the specified outlet pressure, the pressure relief pilot valve opens and simultaneously releases the pressure in the pressure chamber. At
this time, the main valve gate is pushed open and keeps the main valve in open state.
When the pressure returns to the safety limit, the pilot valve closes simultaneously, pressure chamber in main valve recovers pressure accumulation state, and main valve can be closed slowly. In this way the pressure inside the pipeline can be maintained.

‧Pressure Adjusting Range
　0.2kgf/cm²～4kgf/cm²
　3kgf/cm²～7kgf/cm²

‧Special orders can be arranged for higher pressure
　adjustment range.
‧In the case of high pressure, valve body made by
　stainless steel is recommended.
