The Hydraforce PR50-38H-0-N-33/25 (5614917.25) is a screw-in, cartridge-style, direct-acting spool type hydraulic pressure reducing/relieving valve. This versatile valve is designed for pressure regulation in secondary circuits and features an internal spring chamber drain alongside a spool damping chamber. It allows bidirectional flow from port 2 to port 1 while maintaining a constant drain at port 3. When the predetermined pressure at port 1 is reached, the valve shifts to block flow at port 2, thereby regulating the pressure at port 1. Additionally, it can relieve pressure from port 1 to port 3 over a set reducing value. The valve boasts several features including non-backout adjustments and optional spring ranges up to 227.5 bar (3300 psi). Constructed with a hardened spool and cage, it promises durability and long life. The PR50-38H-0-N-33/25 can handle pressures up to 344.7 bar (5000 psi) for ports 1 and 2 and up to 68.9 bar (1000 psi) for port 3, with proof pressures of up to 482.6 bar (7000 psi). It has a burst pressure capacity of up to 1034 bar (15000 psi). The valve operates effectively within fluid temperature ranges of -40 to 100 \u00b0C with Buna N seals and -26 to 204 \u00b0C with fluorocarbon seals, among other options. Its corrosion resistance is rated at a remarkable PR50-38XX standard of a 960-hour salt spray per ASTM B117. The unit weighs between approximately 0.26 kg and 0.31 kg depending on configuration and fits into VC10-3 cavities requiring installation torques ranging from about 33.9 N-m to a maximum of about 67.8 N-m for cartridge installation, making it suitable for various hydraulic applications needing reliable pressure control solutions.
