The Hydraforce TS58-21F-0-P-12ER-M276 (5123284.M276) is a direct-acting, poppet-type, proportional pressure relieving valve designed to regulate pressure inversely with the input electrical current. It effectively blocks flow from port 1 to port 2 until sufficient pressure is applied to open the valve, making it suitable for applications requiring precise pressure control. This model accommodates both 12 and 24 volt coils, with optional waterproof E-Coils rated up to IP69K for enhanced durability in harsh environments. The valve fits an industry-common cavity and features hardened parts for extended operational life. Key specifications include a pressure rating of up to 413.7 bar (6000 psi) at port 1 and up to 103.4 bar (1500 psi) at port 2, with proof pressures reaching 448.2 bar (6500 psi) and burst pressures of 758.4 bar (11000 psi). The adjustable pressure range spans from 6.9 to 351 bar (510 to 5000 psi), while the flow rating is set at 1.9 lpm (0.5 gpm) with a maximum internal leakage of just 4.5 ml/min at optimal settings. Temperature tolerances are broad, accommodating operating fluid temperatures from -40 to 100 \u00b0C (-40 to 212 \u00b0F) with buna N seals, extending further depending on seal material used, such as fluorocarbon or polyurethane seals. The valve also boasts substantial corrosion protection withstanding up to 960 hours of salt spray per ASTM B117 standards and supports fluid viscosities ranging from 7.4 to 420 cSt while maintaining cleanliness levels per ISO standards. Installation specifications highlight its VC08-2 cavity requirement with a cartridge installation torque between 32.5 and 35.3 N-m, ensuring secure fitting without orientation restrictions. Additional components include various seal kits and housing options available for versatile application needs.
