The Hydraforce SV12-21K-0-N-00 (5049012) is a solenoid-operated, 2-way, normally open, poppet-type, screw-in hydraulic cartridge valve. This valve is specifically designed to function as a load holding or blocking valve in systems that require minimal internal leakage. In its default state when de-energized, the SV12-21K-0-N-00 permits fluid flow from port 1 to port 2 while severely restricting flow in the reverse direction. Upon activation (energizing), the valve's poppet closes against its seat effectively blocking flow from port 1 to port 2 and thus functioning as a check valve that allows flow from port 2 to port 1 after overcoming the solenoid force. This model features a continuous-duty rated coil and a hardened seat which ensures longevity and maintains low leakage levels. The efficient wet-armature construction along with optional coil voltages and terminations provide versatility for different system requirements. The cartridges are voltage interchangeable which adds to the flexibility in usage. Furthermore, this unit includes a unitized, molded coil design and offers an optional manual override feature. For environments requiring robust durability, optional waterproof E-Coils rated up to IP69K are available. The SV12-21K-0-N-00 is designed for easy installation in VC size-way cavities and does not have orientation restrictions during installation. It supports various hydraulic fluids including mineral-based or synthetic types with lubricating properties within a fluid viscosity range of 10 to 380 cSt. The operating parameters include pressure ratings up to 350 bar (5076 psi) and temperature tolerances ranging from -40°C to +120°C (-40°F to +248°F), depending on the seal material used (Buna N, Fluorocarbon, or Polyurethane). This makes it an efficient choice for diverse hydraulic applications needing reliable load holding or blocking capabilities without significant pressure drop or leakage.
