The Hydraforce TS38-21D-0-N-00 (5122992) is a direct-acting, spool-type proportional pressure relieving valve designed for precise control of hydraulic systems. This valve regulates pressure inversely with the input electrical current, ensuring optimal system performance. It features robust construction with hardened parts for extended service life and operates within an industry-standard cavity. The TS38-21D model is equipped with a 12 or 24-volt coil, with an optional waterproof E-Coil rated up to IP69K for enhanced durability in harsh environments. The valve effectively manages flow from port 1 to port 2, opening only when sufficient pressure at port 1 overcomes the preset spring force. Without electrical current, it relieves pressure at its maximum range; applying current reduces the spring force and adjusts the valve setting accordingly. Pressure ratings include a maximum of 289.6 bar (4200 psi) at port 1, with proof pressures up to 344.7 bar (5000 psi) and burst pressures reaching 758.4 bar (11000 psi). The adjustable pressure range spans from 6.9 to 241.3 bar (100 to 3500 psi), catering to various operational needs. Flow capacity is rated at 1.1 lpm (0.3 gpm), with hysteresis levels varying by configuration\u20142.5% for settings (a) and (d), and up to 5% for setting (c). The TS38-21D accommodates fluid temperatures from -40 to 204 \u00b0C (-40 to 400 \u00b0F), depending on seal material, and supports mineral or synthetic fluids with viscosities between 7.4 and 420 cSt. Installation specifications include a VC08-2 cavity requirement, cartridge installation torque of 25.8 to 28.6 N-m, and no orientation restrictions during setup. Corrosion resistance is assured with a rating of up to 960 hours in salt spray conditions per ASTM B117 standards, making it suitable for demanding applications requiring reliable performance under variable conditions.
