Pneumatic Upward Downward Expansion Discharge Globe Valve

Pneumatic upward expansion discharge valve installed in the upper part of the pipeline, when the valve is closed, can prevent the material to the upper discharge; The pneumatic downward expansion discharge valve is installed in the lower part of the pipeline. When the valve is closed, the material can be prevented from discharging down. The working principle of both is to use pneumatic actuator to control the opening and closing of the valve. When the valve is closed, the sealing plate inside the valve will expand, so as to realize the sealing of the material.
