The Hydraforce PR58-38H-0-N-32/32 (5606457.32) is a screw-in, cartridge-style hydraulic pressure reducing/relieving valve. This direct acting, spool type valve features an internal spring chamber drain and a spool damping chamber, making it ideal for pressure regulation in secondary circuits. In its default state, it allows bidirectional flow from port 2 to port 1 while maintaining constant drainage at port 3. When the pressure at port 1 reaches a set threshold, the valve shifts to block flow at port 2 and relieve pressure from port 1 to port 3. The valve can optionally include a 233-micron screen for added protection. It offers optional spring ranges up to 248 bar (4200 psi) and is built with hardened spool and cage components for enhanced durability in compact, industry-standard dimensions. The PR58-38H-0-N-32/32 is rated for pressures up to 344.7 bar (5000 psi) with a proof pressure of 379.2 bar (5500 psi) and burst pressure of 896.3 bar (13000 psi). It supports flow rates of up to 18.9 lpm (5 gpm). Operating fluid temperatures range from -40 to 100 \u00b0C (-40 to 212 \u00b0F) with Buna N seals, -26 to 204 \u00b0C (-15 to 400 \u00b0F) with fluorocarbon seals, and -54 to 107 \u00b0C (-65 to 225 \u00b0F) with polyurethane seals. The unit weighs between 0.22 kg and 0.28 kg depending on specific configurations and has an internal wetted surface area ranging from 141 cm\u00b2 to166 cm\u00b2. Installation requires a VC08-3 cavity with torque specifications ranging between 32.5 N-m and a maximum of47.5 N-m for cartridge installation, ensuring secure placement without orientation restrictions. Optional seal kits are available under part numbers SK08-3X-BM or SK08-3U-OO depending on seal options chosen during installation.
