Product Description

Product Description

 

Our hydraulic water pressure relief valves are engineered to automatically regulate pressure levels in various systems, making them ideal for municipal water systems, rural water systems, industrial plants, storage tanks, and fire protection systems. These automatic relief valves can be used in both modulating and on-off services, with the pressure control being either valve-mounted or operated remotely. They also offer feature combinations such as pressure sustaining and solenoid (on-off) capabilities.

Features and Benefits:

 • Automatic control valve for efficient, self-running operation
 • Integrated disc design for easy maintenance
 • Constructed with a stainless steel piston cylinder, integral cast piston, and NBR sealing ring for extended service life
 • Large inner chamber reduces noise from cavitation and lowers static pressure.
 • For guide hole piston cylinders, increasing resistance ensures more stable piston movement.
 • Corrosion-resistant stainless steel and bronze components.
 • Reinforced Nylon + EPDM diaphragm for a long lifespan.

Order value less than 2000USD, 100% in advance. Order value more than 2000USD, 30% T/T in advance, balance before shipment. L/C available as well.

How does a hydraulic water pressure relief valve work?
When the pressure in a hydraulic system exceeds the set value, the hydraulic water pressure relief valve automatically opens, releasing the excess pressure until the system returns to a safe pressure level, and then the valve closes.

Where can hydraulic water pressure relief valves be used?
Hydraulic water pressure relief valves are widely used in water supply systems, firefighting systems, irrigation systems, industrial hydraulic systems, and any other applications requiring pressure protection.

How do I install a hydraulic water pressure relief valve?
Installation steps may vary depending on the specific model, but generally involve mounting the valve at an appropriate location in the hydraulic system and ensuring tight, leak-free connections. Detailed installation instructions can be found in the product manual.

How do I choose the right hydraulic water pressure relief valve for my application?
Choosing the right valve involves considering the system's maximum operating pressure, flow rate requirements, type of medium, and installation environment. Refer to the product specifications and consult a professional if needed.

Can I adjust the set pressure of a hydraulic water pressure relief valve myself?
Yes, most hydraulic water pressure relief valves allow user adjustment of the set pressure. Follow the instructions in the product manual for accurate adjustment.
