Direct-operated solenoid valve SV12-Z0

2-waynormally closedhydraulic

A solenoid operated, 2-way, normally closed, poppet-type, screw-in cartridge valve, designed for low leakage in load holding or blocking applications. Operation When de-energized, the SV12-Z0 acts as check valve, allowing flow from ① to ② and blocking flow in the opposite way. When energized, the cartridge's poppet lifts to open the ② to ① path, in which condition the ① to ② flow is severely restricted. To open the ① to ② path, please refer to SV12-Z2. Features Unitized molded coil design, continuous-duty rated coil, cartridges are voltage interchangeable, optional for 24V and 12V coil voltage. Coil insulation grade: H, coil protection grade: IP65. Hardened seat for long life and low leakage. Efficient wet-armature construction. Industry common cavity. Flow: See performance chart Internal leakage: 0.15 mL/min (3 drops/min) max. at 250 bar (3500 psi) Coil duty rating: Continuous from 85% to 115% of nominal voltage Response time: First indication of change of state with 100% voltage supplied at 80% of normal flow rating. Energized: 40 ms; De-energized: 80 ms Initial coil current draw at 20°C: Standard coil (22W) : 12V (1.83 A) , 24V (0.92 A) Coil models: SCO116-DC12, SCO116-DC24 Minimum pull-in voltage: 85% of nominal at 250 bar (3600 psi) Filtration: See other notes Fluid: Mineral based or synthetics with lubricating properties at viscosities of 7.4~420 cSt (50-2000 ssu) Installation: No restriction Cavity: V12-2
