The Hydraforce TS38-21C-0-N-00 (5122818) is a direct-acting, spool-type, proportional pressure relieving valve designed to provide precise pressure control in hydraulic systems. This valve operates by blocking flow from port 1 to port 2 until sufficient pressure at port 1 overcomes the preset spring force, allowing the flow to pass through. The regulated pressure is inversely proportional to the input electrical current, meaning that as electrical current increases, the pressure setting decreases. This model features a 150 mesh screen for protection at port 1 and offers standard coil voltages of 12 and 24 volts, with optional waterproof E-Coils rated up to IP69K for enhanced durability in harsh environments. The TS38-21C-0-N-00 is equipped with hardened parts for extended service life and fits into industry-common cavities, specifically the VC08-2 or 08-size-2-way cavities. It has a maximum pressure rating of up to 289.6 bar (4200 psi) at port 1 and an adjustable pressure range from 6.9 to 241.3 bar (100 to 3500 psi). The valve's proof pressure stands at 344.7 bar (5000 psi) for port 1 and burst pressure reaches up to an impressive 758.4 bar (11000 psi). With a flow rating of up to 1.1 lpm (0.3 gpm), this valve maintains efficient operation with minimal hysteresis percentages varying between different settings: as low as 2.5% in certain configurations. It supports operating fluid temperatures ranging from -40\u00b0C (-40\u00b0F) with buna N seals up to +204\u00b0C (+400\u00b0F) with fluorocarbon seals, making it suitable for various applications requiring robust temperature tolerances. Additional features include corrosion protection tested for up to 960 hours of salt spray per ASTM B117 standards and compatibility with mineral-based or synthetic fluids possessing lubricating properties within a viscosity range of 7.4 to 420 cSt. Installation requires specific torque values: cartridge installation torque ranges from 25.8 to 28.6 N-m (19 to 21 ft-lb), while coil nut torque ranges from 5.4 to 6.8 N-m (4 to 5 ft-lb). Optional seal kits are available under part numbers SK08-2N-B, SK08-2V-B, SK08-2P-B, and SK08-2U-O for maintenance needs.
