The Hydraforce SV12-21K-0-N-24DG (5049063) is a solenoid-operated, 2-way, normally open, poppet-type, screw-in hydraulic cartridge valve. It is specifically designed to function as a load holding or blocking valve in systems where low internal leakage is critical. This valve exhibits unique operational characteristics; when de-energized, it allows fluid flow from port 1 to port 2 while severely restricting flow from port 2 to port 1. Upon energization, the valve’s poppet closes against its seat, effectively blocking flow from port 1 to port 2 and acting as a check valve that permits flow in the opposite direction once the solenoid force is overcome. Key features of this model include a continuous-duty rated coil and a hardened seat that ensures longevity and minimal leakage. It offers optional coil voltages and terminations for versatility in application and an efficient wet-armature construction that enhances its performance. The cartridges are voltage interchangeable which adds to the flexibility in usage. Additionally, this unit boasts a unitized, molded coil design and provides 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-24DG supports various hydraulic fluids including mineral-based or synthetic types with lubricating properties within a viscosity range of .3 to 860 cSt. It operates efficiently within a fluid temperature range of -40°C to +120°C with Buna N seals and has specific pressure ratings including proof pressure up to . bar ( psi) and burst pressure up to . bar ( psi). This model is designed for easy installation into VC size-16 cavities without orientation restrictions and requires specific torques for cartridge installation ranging from .5 Nm (7 ft-lb) to . Nm ( ft-lb).
