A735X Type Water Hammer Relief Valve, primarily used on pump discharge pipelines, achieves automatic control through pressure transmission via hydraulic conduits, featuring the following characteristics:

Core Functions

‌Prevent Water Hammer: In the event of pipeline pressure exceeding the set value, the valve quickly opens to relieve pressure, preventing damage to the pipeline and equipment caused by water hammer.‌

Power Failure Protection: Capable of sensing low or high voltage surges in advance during sudden power outages or pump shutdowns, it initiates the drain circuit early to prevent negative or positive pressure water hammer.

‌Auto-Adjustment: No external power or mechanical device required; automatic adjustment is achieved through the pressure transmission of hydraulic conduits.‌

Technical Specifications

Nominal Pressure: Supports various pressure grades such as 1.0MPa, 1.6MPa, 2.5MPa, and 4.0MPa.

Set Pressure: Simultaneously set high, low pressure, and power-off start-up pressure with an error less than 0.02 MPa.

‌Reaction Time: High-pressure water release reaction time ≤ 1 second.‌

Applicable Scenarios

Suited for high-rise buildings, fire water supply systems, and various water supply systems, especially on pipeline sections prone to water hammer, such as at pump outlets and check valves.
