Product Advantages

**Product Features**

Application Scenarios

- Porting patterns compatible with DIN 24 340, ISO 5781, and CETOP-RP 121H standards.

- Pilot operated check valve design ensuring leak-free operation.

- Check-Q-meter function controls returning flow relative to actuator flow, accommodating cylinder area ratios.

- By-pass valve permits free flow in the reverse direction.

- Optional integrated secondary pressure relief valve available for flange connection models.

**Product Value**

The valves support safe and stable hydraulic system operation by preventing runaway speeds in motors and cylinders and providing pipe burst safety isolator functions. They are suitable for high-pressure applications (up to 42 MPa) and wide flow ranges (80 to 560 L/min), ensuring versatile use in demanding hydraulic environments while maintaining high durability and long service life.

**Product Advantages**

- Manufactured under rigorous quality tests to ensure consistent performance and impeccable craftsmanship.

- Advanced design includes damping and pilot components for precise flow control.

- Compatible with a broad range of hydraulic fluids and temperature conditions (-30°C to +80°C).

- The company maintains high production standards and uses international-level surface roughness and installation specifications for superior integration.

- Strong technical support and a young, efficient, and quality-focused team drive continuous innovation and customer satisfaction.

**Application Scenarios**

Ideal for various hydraulic systems requiring precise flow control and safety functions, including industrial machinery, construction equipment, and mobile hydraulics. They are used where controlling actuator speeds independently of load and ensuring system safety from pipe bursts is critical. Suitable for use in environments requiring robust pressure control under fluctuating flow and temperature conditions.
