The Hydraforce SV08-21-0-N-24ER (5001099) is a solenoid-operated, 2-way, normally open, poppet-type screw-in hydraulic cartridge valve, engineered specifically for low leakage in load-holding applications. This valve is designed to allow flow from port 2 to port 1 when de-energized; however, the flow from port 1 to port 2 is significantly restricted under these conditions. Upon energization, the valve's poppet closes firmly against its seat to block flow from port 2 to port 1 completely. The valve requires overcoming the solenoid force to enable flow from port 1 to port 2. Constructed for durability and reliability, the SV08-21 features a hardened seat that ensures long life and minimal leakage. It offers versatility with options for different coil voltages and terminations, making these cartridges interchangeable across various voltage requirements. The unitized, molded coil design enhances its robustness, while an optional manual override provides additional operational flexibility. This model also supports optional waterproof E-Coils rated up to IP69K for superior protection against dust and high-pressure water ingress, making it suitable for harsh environments. Its compact size and industry-common cavity make it easy to integrate into a wide range of hydraulic systems without requiring extensive modifications. Additional features such as continuous-duty rated coils and the use of high-quality materials like steel with zinc plating and Buna N O-rings with Teflon backup rings underscore its suitability for demanding applications. The SV08-21-0-N-24ER operates effectively within a fluid temperature range of -40°C to +120°C and can handle pressures up to 207 bar (3000 psi), with maximum internal leakage maintained at a minimal rate of five drops per minute at maximum pressure.
