The Hydraforce SV10-21-0-N-00 (5021008) is a solenoid-operated, 2-way, piloted, poppet-type, normally open hydraulic cartridge valve designed for applications requiring low leakage and load-holding capabilities. This valve operates by allowing flow from port 2 to port 1 when de-energized; flow is severely restricted from port 1 to port 2 in this state. Upon energization, the valve's poppet closes against its seat to block flow from port 2 to port 1, while allowing flow from port 1 to port 2 once the solenoid force of 50 to 150 psi (3.4 to 10.3 bar) is overcome. Key features of the SV10-21-0-N-00 include a continuous-duty rated coil and a hardened seat that ensures long life and minimal leakage. It offers optional coil voltages and terminations, efficient wet-armature construction, and cartridges that are voltage interchangeable. The design also includes a unitized, molded coil and a manual override option. For enhanced durability in various environments, optional waterproof E-Coils rated up to IP69K are available. The valve supports a maximum flow rate of 27 gpm (102 lpm) at a pressure of 500 psi (34.4 bar), with maximum internal leakage specified at only three drops per minute at a pressure of 3000 psi (207 bar). It can operate effectively within fluid temperatures ranging from -40°C to +100°C (-40°F to +212°F) with Buna N seals, or up to +204°C (+400°F) with fluorocarbon seals. Physically, the SV10-21-0-N-00 weighs approximately 0.16 kg (0.35 lb) for the cartridge alone and about 0.46 kg (1.02 lb) when equipped with an E-coil. It has been designed for use in VC102 cavity installations with specific torque requirements for cartridge installation and coil nut tightening provided in its specifications. This robust valve assembly is versatile for various hydraulic applications where reliable performance and durability are critical.
