The Hydraforce 5616912P.27.5 (5616912P.27.5) is a spool type, pilot-operated hydraulic pressure reducing/relieving valve, specifically designed for secondary circuit pressure regulation. This component features an internal pilot and internal spring chamber drain, facilitating its role as a pressure-regulating device. In its steady state, the PR12-36X model allows bidirectional flow from port 2 to port 1 while maintaining a constant drain in the spring chamber at port 3. When the predetermined pressure at port 1 is reached, the spool shifts to restrict inlet flow from port 2, effectively regulating the pressure at port 1 and relieving it to port 3 if necessary. It is important to note that tank pressure adds to the regulated pressure in this configuration. The valve's design ensures that adjustments cannot be backed out and prevents springs from becoming solid during operation. Additionally, it offers optional spring ranges up to 207 bar (3000 psi), providing flexibility in various applications requiring precise pressure management and relief functions in hydraulic systems.
