The Hydraforce HSP12-20-0-U-00 (5539090) is a high-pressure, 2-way, piloted, poppet-type, proportional, normally closed screw-in hydraulic cartridge valve specifically designed for low leakage blocking in load holding applications. This valve exhibits exceptional functionality by blocking flow from ports 2 to 1 when deenergized and permitting flow from ports 1 to 2 after overcoming the spring forces. Upon energization, it allows proportional flow from ports 2 to 1 while severely restricting flow in the opposite direction. Equipped with a manual override for emergency use, it requires clockwise rotation for normal operation and counterclockwise rotation for manual shifting. The HSP12-20-0-U-00 is built for durability and reliable performance with features including a continuous-duty rated coil and efficient wet-armature construction. Its E-Coils are waterproof up to IP69K standards ensuring suitability in various environmental conditions. The valve also offers linear metering options and can handle pressures up to 350 bar (5075 psi) with proof pressure at 690 bar (10000 psi) and burst pressure reaching up to 1380 bar (20000 psi). It supports a maximum flow rate of 84.3 lpm (22.3 gpm) and demonstrates minimal internal leakage. Ideal for sophisticated hydraulic systems requiring precise control and reliability, this valve stands out with its robust design tested according to NFPA specification T2.6.1., ensuring high levels of performance verification and assurance. Additionally, it can operate across a wide range of temperatures and is compatible with various seal materials including Buna N, fluorocarbon, and urethane for diverse application needs.
