Description & Features

CV4400 Pneumatic Diaphragm On Off Ball Valve


CV4400 ball valve can be full opened or closed by simply causing the stem to make a quarter turn, while valve is full open the fluid resistance is negligible cause the bore as pipeline, therefore, it’s best suitable to on off service of fluids as fiber, suspension captaining tiny solids and viscous fluid.


Compact, low weight, small volume.


Full bore design standard, and reduced bore available.


Spring loaded seat, tight shut-off and bidirectional seal.


Self-lubricating bearing, stable operation and superior abrasion resistant.


Low flow resistance.


90 degree rotation, quick open and close.


Blow-out proof stem.


Anti-static device.
