The Hydraforce PR58-38A-0-N-20 (Material Number: 5606451) 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, making it an effective pressure regulating device for secondary circuits. In its steady state, the valve allows bidirectional flow from port 2 to port 1 while maintaining a constant drain at port 3. When a predetermined pressure at port 1 is reached, the cartridge shifts to block flow at port 2, thereby regulating the pressure at port 1 and relieving it to port 3 if necessary. This model can be equipped with optional spring ranges up to 248 bar (4200 psi) and an optional 233-micron screen for additional protection. It boasts hardened spool and cage components for enhanced durability and comes in a compact size that fits industry-standard dimensions. The PR58-38A-0-N-20 has impressive operational capabilities with a maximum pressure rating of 344.7 bar (5000 psi), proof pressure of 379.2 bar (5500 psi), and burst pressure of up to 896.3 bar (13000 psi). It supports a flow rating of up to 18.9 liters per minute (5 gallons per minute). The valve operates efficiently across various temperature ranges depending on seal material\u2014Buna N seals function between -40 to 100 \u00b0C (-40 to 212 \u00b0F), fluorocarbon seals from -26 to 204 \u00b0C (-15 to 400 \u00b0F), and polyurethane/urethane seals from -54 to 107 \u00b0C (-65 to 225 \u00b0F). The unit is compatible with mineral-based or synthetic fluids that have lubricating properties within a viscosity range of 7.4 to 420 cSt, ensuring versatility in different hydraulic systems. Installation requires specific torque values for both cartridge and plug components, ensuring secure integration within VC08-3 cavities or equivalent housings.
