Reliable Pressure Protection
The Relief Valves automatically limit hydraulic system pressure by opening when the preset pressure is reached. This helps protect pumps, actuators, and other hydraulic components from overload.

High Pressure Capability
Designed for demanding hydraulic applications, the valve supports a maximum operating pressure of 350 bar, making it suitable for industrial and mobile hydraulic systems requiring dependable pressure protection.

Low Internal Leakage
The direct-acting poppet relief valve features a poppet sealing design with internal leakage below 30 ml/min, making it suitable for low-flow hydraulic circuits where pressure stability and sealing performance are important.

Wide Operating Temperature Range

The hydraulic cartridge relief valve operates within a temperature range of -30°C to +120°C. Hydraulic oil filtration of 20 μm or better is recommended to maintain stable pressure performance and extend valve service life.

Compact Cartridge Installation
The threaded cartridge design simplifies installation and maintenance while allowing easy integration into hydraulic manifolds and compact hydraulic systems.

1. What is a direct-acting hydraulic relief valve used for?
A direct-acting hydraulic relief valve is used to limit maximum system pressure and protect hydraulic components from overpressure. It is commonly installed in hydraulic power units, manifold blocks, and pressure protection circuits.

2. Which models are available in this series?
Representative models include XRV-08S, XRV-08, XRV2-08, XRV-08-20, XRV-10-20, XNRV-08, XNRV-10, XNRV2-10, XNRV-12, XRDBA, XRDDA, and XRDFA. Additional models may be available for different applications.

3. Are all models supplied with the same technical specifications?
No. The technical data shown on this page are based on Model XRV-08S. Pressure ratings, cavity sizes, flow characteristics, and adjustment ranges may vary depending on the selected model.

4. Why is a low leakage relief valve important?
Low internal leakage helps maintain pressure stability, improves hydraulic efficiency, and is particularly suitable for low-flow hydraulic circuits where precise pressure control is required.

5. How can I choose the right Direct Acting Poppet Relief Valve?
Model selection depends on operating pressure, pressure setting, cavity size, flow requirements, hydraulic fluid, and system design. Our engineering team can recommend the appropriate Relief Valves Direct Acting Poppet Type model based on your application requirements.
