AirTAC Type 5/2 Way 1/4'' Double Coil Pneumatic Solenoid Valve 24VDC 220VAC 4V220-08
The 5/2 way pneumatic solenoid valves usually have single solenoid and double solenoid. Single solenoid valve has one coil and double solenoid valve has two coils.This pneumatic solenoid valve is used to control the flow of the compressed air. Actually both of pneumatic solenoid valve have silimiar operating principle.
Power on the positive-action coil of the double solenoid valve, and the positive-action gas circuit will be connected with the power (or the positive-action outlet has the gas flow). Even if the positive-action coil is disconnected with power, the gas circuit is still connected with the power and remains until electrification of the reverse-action solenoid valve.
If the reverse-action coil is powered on, the reverse-action gas circuit is connected with power (or the reverse-action outlet has the gas flow). Even if the reverse-action coil is disconnected with power, the reverse-action gas circuit is connected with the power, which will remain until electrification of the positive-action coil. This is similar to "self-locking".
4V Series Solenoid Valve Features:
1. Pilot-oriented mode: optional for internal or external;
2. Structure in sliding column mode: good tightness and sensitive reaction;
3. Internal hole adopts special processing technology which has little attrition friction, low start pressure and long service life;
4. It is available to form integrated valve group with the base to save installation space;
5. Affiliated manual devices are equipped to facilitate installation and debugging;
6. Several standard voltage grades are optional;

Installation Instructions:
1. Before installing, be sure the valve hasn’t been damaged via transportation.
2. It’s suggested to use the medium lubricated by 40μm filter element. Be aware of the flow direction and port size.
3. Please notice whether the installation condition accords with technical requirements (such as “voltage”, “actuation frequency”, “working pressure” and “scope of application temperature”), then the equipment can be installed and used.
4. Notice the flow direction of air during installation, P is the air intake, A (B) is the work port and R (S) is the exhaust outlet.
5. Take measure to avoid vibration and frozen.
6. Before using the fittings and tubes make sure they are clean. When connecting to fittings, be sure the PTFE Thread Seal Tape is used correctly.
7. To keep the dust away, please use the silencer for the exhaust ports. Never forget to install dirt-proof boot in air intake and outlet during dismounting.
8. After installing, please use the manual override to test valve first.
