The Hydraforce 5616940.03.75 (5616940.03.75) is a spool type, pilot-operated hydraulic pressure reducing/relieving valve designed for secondary circuit pressure regulation. Known as the PR12-36X, this valve allows bidirectional flow from port 2 to port 1 in its steady state while maintaining a constant drain at port 3 through its internal spring chamber. When the pressure at port 1 reaches a predetermined level, the spool shifts to restrict inlet flow from port 2, effectively regulating the pressure at port 1 and also relieving any excess pressure from port 1 to port 3. It is important to note that tank pressure contributes to the regulated pressure. The design includes adjustments that cannot be backed out of the valve and ensures that springs do not go solid during operation. Additionally, there are optional spring ranges available up to 207 bar (3000 psi), offering flexibility in various applications where precise pressure control is required for optimal performance of hydraulic systems.
