805315119 - 2-WAY - SVP08-NCR-00-00-B-00 - DANFOSS
Solenoid Valve, 2-way, Poppet Type, Normally Closed, Pilot Operated with Reverse Free Flow.
This is a 2-way, 2-position, poppet type, pilot operated, normally closed solenoid valve. In its de-energized condition, flow passes from port 1 to 2 but is blocked in the opposite direction. When energized, flow passes from port 2 to 1 and from 1 to 2. Some models have the option of a filter at port 2. Due to the low leakage provided by the poppet design, these valves can be used to hold loads in position or to interrupt a pressure line where flow normally passes in both directions.

Function: 4 WAY-3 POS ON-OFF SPOOL VALVE
Solenoid Valve, 4-way, 3-position, Spool Type 230 bar [3300 psi] • 8 l/min [2 US gpm]
This is a 4-way, 3-position, spool type, direct acting solenoid valve. In the center condition, ports 2 and 4 are closed while port 3 is connected to port 1. By energizing one coil, port 3 opens to 2 and port 4 to 1. When energizing the other coil, port 3 opens to 4 and port 2 to 1. This valve provides a directional control function with a neutral de energized state allowing the inlet flow to pass to tank or to another function while the work ports are blocked. It can be used in any hydraulic application where an actuator needs to be controlled in both directions.
