The Hydraforce SP08-20M-0-N-00 (5003403) is a solenoid-operated, 2-port, normally closed, poppet-type, proportional screw-in hydraulic cartridge valve. It is specifically designed for low leakage blocking and load-holding applications. In its default state when de-energized, the SP08-20M functions as a check valve allowing hydraulic fluid to flow from port 1 to port 2 while blocking the flow in the reverse direction. Upon energization, the valve’s poppet lifts to permit flow from port 2 to port 1. This model is engineered for continuous duty and features an efficient wet-armature construction. It offers manual override options and can be fitted with optional waterproof E-Coils that are rated up to IP69K, ensuring suitability for harsh environments. The compact design of the SP08-20M incorporates an industry common cavity (VC082), which facilitates ease of installation and maintenance. The valve handles a maximum operating pressure of 207 bar (3000 psi) and can withstand proof pressures up to 413 bar (6000 psi). It has been tested for burst pressures up to 827 bar (12000 psi). Suitable for a wide range of temperatures, it operates efficiently with fluid temperatures ranging from -40°C to +100°C with Buna N seals, -26°C to +204°C with fluorocarbon seals, and -54°C to +107°C with polyurethane seals. The SP08-20M is constructed from steel with hardened work surfaces and zinc-plated exposed surfaces for durability and corrosion resistance. Its internal wetted surface area measures approximately 85.2 cm² (13.2 in²), and it has an overall unit weight of about 0.10 kg (0.23 lb), or approximately 0.10 kg (0.94 lb) including the coil. This valve is ideal for various hydraulic applications where precise control of fluid handling is necessary under varying pressure conditions without leakage.
