OEM HITACHI ZAXIS ZX SERIES HYDRAULIC RELIEF VALVE | Tonkee®

The primary function of the hydraulic relief valve is to limit the pressure in a hydraulic system to a safe and predefined level.

It acts as a safety mechanism to prevent damage to the system components, including pumps, hoses, and cylinders. When the system pressure exceeds the set limit, the relief valve opens, allowing excess fluid to flow back to the reservoir or another low-pressure area.

Pressure Rating:
The pressure rating of the Hitachi ZAXIS ZX Series Hydraulic Relief Valve is a critical specification. It determines the maximum pressure at which the valve will begin to relieve excess pressure. These relief valves are typically available in various pressure ratings to suit different hydraulic system requirements. Common pressure ratings range from 1000 to 5000 psi (pounds per square inch).

Flow capacity is another essential specification. It denotes the maximum flow rate of hydraulic fluid that the valve can handle while relieving excess pressure. Proper sizing of the relief valve's flow capacity ensures that it can effectively handle the hydraulic system's demands. The ZAXIS ZX Series offers various models with different flow capacities to accommodate a wide range of applications.

Hitachi is known for its high-quality construction, and the ZAXIS ZX Series Hydraulic Relief Valve is no exception. These valves are typically constructed from robust materials such as hardened steel or alloy, ensuring durability and longevity even in demanding industrial environments.

Adjustable vs. Non-adjustable:
Some relief valves are adjustable, allowing operators to set the desired pressure limit within a specified range. Non-adjustable relief valves have a fixed pressure setting.

The choice between adjustable and non-adjustable relief valves depends on the specific application requirements.

The mounting type of the relief valve is crucial for compatibility with the hydraulic system. Common mounting options include inline, subplate, and manifold-mounted relief valves. The choice depends on the system's design and space constraints.

Sealing:
Effective sealing is essential to prevent leaks and ensure the valve operates as intended. High-quality seals and gaskets are used in the Hitachi ZAXIS ZX Series Hydraulic Relief Valve to maintain a tight seal and prevent hydraulic fluid from escaping.

Temperature Range:
Hydraulic systems can operate in a wide range of temperatures. The relief valve should be capable of functioning reliably within the specified temperature range of the application.
