Description
Product Description
Serving as the core defense line for system pressure, the ASHUN MRV Series Relief Modular Valves utilize highly integrated modular designs that mount directly beneath directional valves, significantly saving manifold block space and eliminating complex piping costs. Through precise straight-moving or booting internal structures, these valves acutely respond to minor circuit pressure changes and rapidly relieve excess fluid during abnormal surges. This mechanism ensures the hydraulic power core is protected from overload damage, making them the ideal choices for advanced automation machinery.
Product Features
- Modular Stacking Installation: Eliminate complex piping tasks to maximize manifold space efficiency.
- Diverse Pressure Settings: Provide multiple pressure ranges to precisely match circuit safety needs.
- Comprehensive Circuit Control: Support P, A, B port configurations to highly adapt to complex systems.
- Responsive Relief Protection: Precisely control pressure boundaries to proactively and rapidly prevent system overload.
