The Hydraforce PR58-38A-6T-N-20 (Material Number: 5606491) is a screw-in, cartridge-style, direct-acting, spool-type hydraulic pressure reducing/relieving valve. This valve features an internal spring chamber drain and spool damping chamber, designed to regulate pressure for secondary circuits. In its steady state, the PR58-38A-6T-N-20 allows bidirectional flow from port 2 to port 1 while maintaining a constant drain at port 3. When the pressure at port 1 reaches a predetermined level, the valve shifts to block flow at port 2, regulating pressure at port 1 and relieving it to port 3 if necessary. The valve can be equipped with an optional 233-micron screen for added protection. It is built with hardened spool and cage components for durability and long service life. The PR58-38A-6T-N-20 offers adjustable spring ranges up to 248 bar (4200 psi) and features adjustments that prevent springs from going solid or being backed out of the valve. It can handle pressures up to a maximum of 344.7 bar (5000 psi), with proof pressure reaching up to 379.2 bar (5500 psi) and burst pressure up to 896.3 bar (13000 psi). The flow capacity is rated at 18.9 lpm (5 gpm). This valve operates within fluid temperature ranges of -40 to 100 \u00b0C (-40 to 212 \u00b0F) with buna N seals and wider temperature ranges with other seal options. Compatible with mineral-based or synthetic fluids possessing lubricating properties, it supports fluid viscosity ranges from 7.4 to 420 cSt and maintains an operating contamination level of ISO code 20/18/14. The valve fits into VC08-3 cavities and requires a cartridge installation torque between 32.5 to 35.3 N-m (24 to 26 ft-lb), with a maximum plug torque of 47.5 N-m (25 ft-lb). Seal kits such as SK08-3X-BM are available for maintenance purposes, ensuring optimal performance in various applications where precise pressure control is essential.
