Explosion-proof electric actuator WCB two way shut off ball valve

Explosion-proof electric actuator WCB two way shut off ball valve

Short Description:

China electric shut off ball valve manufacturer,factory and supplier with best price,Electric stainless steel shut off ball valve is composed of 304 316 316L and other stainless steel ball valve and switch type,integral type,adjusting type,intelligent type electric actuator with voltage of AC220V, AC110V, AC380V, Electric stainless steel shut off ball valve is small in size, light in weight, large in thrust, strong in function, servo amplifier is installed inside, easy to operate, high in reliability, ball valve and actuator adopts direct connection mode, built-in servo system, without the need for additional servo amplifier, input and output signals 4-20mA and 220VAC power supply can be controlled operation.Electric stainless steel shut off ball valve has the advantages of simple connection, compact structure, stable and reliable operation.Electric carbon steel on off ball valve is an important type of electric valve, which is widely used in petrochemical industry and long distance pipeline.The shutoff is a partially perforated ball that rotates with the stem to open or close the valve.Electric stainless steel shut off ball valve can cut off and circulate the medium in the transportation pipeline such as petroleum, chemical industry, papermaking, metallurgy, sewage treatment and oil tank truck.

Working Principle

Electric flanged ball valve based on the power with DC24V, AC220V or AC380V, input signal (4-20mA DC, 0-10mA DC or 1-5V DC, 0-10V DC), turn the corresponding displacement with the input signal into the angle displacement (0 ~ 90 °), control the rotation opening of the ball. Then input signal corresponds the displacement to achieve proportional adjustment. (The two-position shut-off type accepts DC24V, AC220V or AC380V power, realizes the switching action through the positive and negative rotation of the motor, and outputs the shut-off valve position signal at the same time).


1. Easy install and can be installed in any place of the pipeline in any direction.
2. A variety of power sources to choose from, and also explosion-proof type.
3. The flow channel in the valve body is smooth to flow viscous fluid, slurry and solid particles.
4, Depends on the direct connection mode, electric actuator has built-in servo system, without additional servo amplifier.
5. There is no bracket connection between the ball valve and the electric actuator. The integrated compact structure reduces the space.
6. The sealing material of PTFE has good self-lubrication and small friction loss with the ball. So that the work life of the ball valve will be longer.
