Description
Product Description
The ASHUN RV Series Relief Valves act as the primary defense mechanism against overpressure in fluid power systems. Offering direct, remote, and pilot-operated designs, these valves seamlessly integrate into manifold blocks or inline piping to establish precise pressure boundaries. By rapidly diverting excess flow back to the reservoir, they actively protect hydraulic pumps and actuators from abnormal pressure spike damage, making them indispensable components for maintaining operational stability in heavy machinery.
Product Features
- Versatile System Adaptability: Offer direct, remote, and pilot options to flexibly match various architectures.
- High-Dynamic Relief Response: Acutely detect circuit spikes and rapidly divert flow to protect components.
- Segmented Precision Regulation: Feature B, C, and H adjustment ranges to strictly guard safety boundaries.
- Seamless Spatial Integration: Dual sub-plated and thread designs significantly enhance manifold layout flexibility.
