The Hydraforce 5614966.18.5 (Material Number: 5614966.18.5) is a screw-in, cartridge-style, direct-acting, spool-type hydraulic pressure reducing/relieving valve. It features an internal spring chamber drain and a spool damping chamber, designed specifically to regulate pressure in secondary circuits. The valve allows bidirectional flow from port 2 to port 1 when in its steady state, with the spring chamber continuously drained at port 3. Once a predetermined pressure is reached at port 1, the cartridge shifts to block flow at port 2, thus regulating pressure at port 1 while also relieving port 1 to port 3 over a variable value above the set reducing pressure. The pr50-38xxx model ensures durability with hardened spool and cage components and offers optional spring ranges up to 227.5 bar (3300 psi). Adjustments are designed such that they cannot be backed out of the valve and prevent springs from going solid, ensuring reliable performance over time. Additionally, an optional screen with a 60 mesh and 250-micron rating can protect Port 2 if needed. This valve's industry-common size makes it adaptable for various applications requiring precise pressure control in hydraulic systems.
