Product Overview
The DANFOSS PRV12-12-S-0-30 is a direct-acting pressure relief valve engineered to protect hydraulic circuits from excessive pressure spikes and to maintain system pressure at a predetermined safe level. As a member of the Danfoss PRV series of pressure control valves, this model operates on a spring-loaded poppet principle: when inlet pressure exceeds the valve’s set cracking pressure, the poppet lifts off its seat and diverts flow to the tank port, thereby limiting the maximum pressure in the circuit. The PRV12-12-S-0-30 is designed for inline or manifold mounting in industrial hydraulic power units, offering precise pressure regulation, fast response to pressure transients, and reliable repeatability. Its robust construction and simple, maintenance-friendly design make it a dependable safety and pressure-limiting component in demanding hydraulic systems.
