The explosion-proof electric ball valve is able to achieve the explosion-proof effect by adopting special structural design and materials to suppress the generation of sparks and the spread of flames.

1. Protective housing: The explosion-proof electric ball valve outer casing is made of fireproof and explosion-proof materials, which can withstand external explosion shock waves and high temperatures.

2. Explosion-proof motor: The explosion-proof electric ball valve uses a specially designed explosion-proof motor, which can operate normally in flammable and explosive environments without producing electric sparks.

3. Explosion-proof control manufacturing: The electrical control system of the explosion-proof electric ball valve also needs to be manufactured in an explosion-proof manner, using explosion-proof components and cables different from ordinary equipment, to ensure that any part of the circuit does not produce sparks or arcs.

4. High-standard testing: The explosion-proof electric ball valve needs to undergo a series of strict tests, such as explosion-proof performance testing, temperature testing, electrical performance testing, etc., to ensure that it can work safely and reliably in real explosion environments.

The actuator on my automated valve operates, but the valve won’t turn. Why?

Most likely the valve stem or actuator coupling is broken.

The electric actuator limit switches or the pneumatic actuator position stops are not correctly adjusted.

Probably because there is no air pressure to the solenoid or dirt has jammed it. Also, debris might be trapped inside the valve. Or, the air pressure is not sufficient to operate the actuator. Remember: measure air pressure at the actuator, not at the compressor.

Maybe. First, be sure that the actuator torque output is sufficient to turn the valve reliably. Second, you will have to fabricate a custom mounting bracket and coupling to connect the actuator to the valve.

The valve will stop somewhere between full open and close. When power is reapplied to the original circuit, the actuator will complete the cycle.

To make the change just remove the actuator from the valve and turn it, or the valve stem, 90 degrees and remount the actuator.

Remove the actuator from the valve and check the valve stem. Most ball valves have stem flats at right angles to the flow when the valve is in the off position. On butterfly valves check the stem flow arrow marking.

Remove the actuator from the valve and check the valve stem. Most ball valves have stem flats at right angles to the flow when the valve is in the off position. On butterfly valves check the stem flow arrow marking.

Check the electric wiring schematic that came with the actuator for the correct hookup. Sometimes a copy is inside the actuator cover. If it is missing, don’t guess about the connections. Call the manufacturer for a schematic.

The actuator is wired incorrectly (check the schematic accompanying the actuator), or the external control switch is not the correct type for the actuator.

Not unless you bought it with an optional speed control.

Actuators and solenoid valves require different types of electrical control switches. SPDT for actuators, SPST for solenoids. Check the actuator wiring schematic for the correct wiring and switch type.
