- 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 of 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.

| 【洩壓閥使用狀態】 |
當管線中的水壓超過洩壓設定質時，洩壓嚮導閥開啟，同時釋放背壓室的壓力，此時主閥閥門亦被管線中的壓力推開，使主閥呈開啟狀態。待管線中壓力回復安全值時，洩壓嚮導閥同時關閉。主閥背壓室恢復儲壓狀態，同時主閥可再緩慢關閉，確保管線內壓力保持安全。（左圖為洩壓閥關閉狀態剖面） |

- Pressure Adjusting Range:
2 kgf/cm2 ∼8 kgf/cm2
5 kgf/cm2 ∼13 kgf/cm2
- The working pressure should be greater than 0.3 kgf/cm2 and gate fully open with 1.5 kgf/cm2 please check the pressure before installation
- Special order can be arranged for higher pressure adjustment range.
- Applied Temperature：-15℃∼80℃
