The Hydraforce 5616912.21 (5616912.21) is a spool type, pilot-operated hydraulic pressure reducing and relieving valve, designed for precise pressure regulation in secondary circuits. This model features an internal pilot and an internal spring chamber drain, allowing it to efficiently manage pressure by adjusting flow between its ports. In its default state, the PR12-36X valve permits bidirectional flow from port 2 to port 1 while maintaining a constant drain at port 3. When a set pressure is reached at port 1, the spool shifts to limit inlet flow from port 2, effectively regulating the pressure at port 1. Additionally, this valve can relieve excess pressure from port 1 to port 3, with tank pressure being additive to the regulated pressure. The design ensures that adjustments cannot be backed out of the valve and prevents springs from reaching a solid state. The PR12-36X offers optional spring ranges up to 207 bar (3000 psi), making it versatile for various applications requiring reliable and adjustable pressure control within hydraulic systems.
