Explosion-proof electric manual ( The handwheel) Pneumatic ball valve

Explosion-proof electric pneumatic valve with manual ball is also called the explosion-proof electric with a handwheel pneumatic ball valve, using hand/electric switching mechanism, for semi-automatic electric preferred form, equipped with a motor and the handwheel operation, this design can be in electric actuators is not electricity, or power failure, the user by flipping the clutch handle for manual operation of pneumatic valve opening and closing, at this point, the electric actuator will remain permanently manual state; When electrified, the clutch will be automatically reset, however, to be sure to keep in mind is that this operation is strictly prohibited in the process of power supply.







explosion-proof electric pneumatic valve with manual ball is industrial automation pipeline in recent years, the use of one type of relatively large pneumatic valve products are treated with fire retardant, antistatic, achieve explosion-proof standards, not only can be applied to normal working condition, in the inflammable and explosive occasions also can ensure safe and reliable operation, widely used in petroleum, chemical industry, metallurgy, light industry and other industrial control field, the gas, liquid, the medium inside the oil pipeline cut, circulation, and adjust the control to use.







with explosion-proof electric hand pneumatic ball valve torque switch protection, can prevent the damage by pneumatic valve is too large torque of pneumatic valve stem, such as pneumatic valve jamming, a foreign body, automatically disconnect the motor power supply, can effectively improve the service life of pneumatic valves and actuators.
