Solenoid Valves Technical Information
2-Way Poppet
SVP08-NCF
OPERATION
This is a normally-closed, pilot-operated, poppet-style 08-size solenoid valve. When de-energized, the SPV08-NCF acts as a check valve, allowing flow from port 1 to port 2, and blocking flow from port 2 to port 1. When energized, the valve’s poppet is shifted and allows restricted flow through the orifice from port 2 to port 1. This valve is available with optional filter and with pull-type manual override.
APPLICATIONS
The SVP08-NCF is designed to function as load holding or blocking valve in applications where low internal leakage and various bleeding flows are required in two different positions. In load holding applications, the circuit should be designed so that the de-energized state is the position that is holding the load. When it is energized, a load lowering function will be achieved via a non-compensated orifice. Example applications include scissor & telescopic manlifts, which use a single-acting cylinder for raising and lowering of the platform. The valve has an additional (optional) threaded pull-type override for emergency lowering via a wire cable or a knob handle.
