The Hydraforce 5614900S.03.5 (5614900S.03.5) is a screw-in, cartridge-style, direct-acting spool type hydraulic pressure reducing/relieving valve designed for secondary circuit pressure regulation. This valve features an internal spring chamber drain and a spool damping chamber, ensuring precise pressure control and stability in hydraulic systems. The PR50-38XXX model allows bidirectional flow from port 2 to port 1 in its default state, with the spring chamber constantly drained at port 3. When the predetermined pressure at port 1 is reached, the cartridge shifts to block flow at port 2, thus regulating pressure at port 1 while also relieving excess pressure from port 1 to port 3 at variable values over the set reducing pressure. The design includes a protective option of a 60 mesh, 250-micron rated screen for port 2, enhancing durability and protection against contaminants. Notably, this valve's adjustments are designed to prevent backing out and ensure that springs do not go solid during operation. It offers optional spring ranges up to 227.5 bar (3300 psi), catering to various application needs while ensuring longevity with its hardened spool and cage construction. Its industry-common size facilitates easy integration into existing systems without requiring extensive modifications or adaptations.
