Kg800 Single & Double Coil Explosionproof Solenoid Valves 12V 24V

According to the product design, these valves use filtered inert gas or air. The working pressure shall not exceed the maximum allowable pressure of 8 bars, and the minimum medium or ambient temperature is -10 10 oC. The installation and maintenance of valves must be carried out by qualified personnel. When installing the valve with ex-mark, make sure that all metals or conductors are effectively grounded and the valve body is grounded through solid bolts.

Pneumatic connection and instructions:
1. Connect the conduit according to the instructions on the nameplate, and the solenoid valve interfaces are G1 and 4
2. Air inlet 1 (inlet of main air supply)
3. Air outlets 2 and 4 (connecting the working hole of the actuator)
4. Exhaust ports 3 and 5 (install muffler)

Description of working principle:
1. When the power is off, 1 and 2 are connected; there is gas at port 2 and no gas at port 4, and the valve is closed.
2. When the solenoid valve is powered on, ports 1 and 4 are connected; there is no gas at port 2 and gas at port 4. The valve is opened. When the power is off, the valve will close automatically.
3. If the valve needs to be opened for a long time, the solenoid valve coil needs to be energized for a long time and will be closed automatically in case of power failure( Double coil control is recommended)
4. When the solenoid valve controls the single-acting actuator, the solenoid valve selects the two-position three-way state (the plug of port 2 is blocked). When powered on, 1 and 4 are connected, the valve opens, and when powered off, the valve closes automatically.
