Product Overview
The HYDAC RV 30 (Part Number: 3129378) is a high-performance direct-acting pressure relief valve engineered for precise system pressure limitation and overload protection in industrial hydraulic circuits. Manufactured by HYDAC, a global leader in fluid power technology, this valve operates on a spring-loaded poppet or seat principle, where hydraulic force acting on the sealing element directly opposes a calibrated compression spring. When system pressure exceeds the preset cracking pressure, the valve opens to divert excess flow to the reservoir, thereby safeguarding downstream components from pressure spikes and maintaining stable operating conditions. The RV 30 is designed for inline or manifold mounting and is widely utilized as a safety and pressure-regulating device in demanding hydraulic power units, test stands, and mobile machinery.
