General Description
A solenoid-operated, 2 way, normally open, poppet-type, screw-in hydraulic cartridge valve, designed to function as a load-holding or blocking valve in applications requiring low internal leakag.
- Continuous-duty rated coil. Hardened seat for long life and low leakage. Optional coil voltages and terminations. Efficient wet-armature construction. Cartridges are voltage interchangeable. Unitized, molded coil design. Manual override option. Optional waterproof E-Coils rated up to IP69K. Industrycommon cavity
Function and Features
When de-energized, the SV16-21 poppet lifts to open the port 2 to port 1 flow path. In this mode, flow from port 1 to 2 is severely restricted. When energized, the port 2 to port 1 flow path is closed. In this mode, the valve acts as a check valve, allowing flow to pass from port 1 to port 2 after overcoming the solenoid force (requires 50 to 100 psi [3,4 to 6,9 bar])
Details
The SV16-21 is a 2/2-way cartridge valve in poppet design. The valve has no manuar override and is configurated without coil. Sealing material is Buna N.
