HK56-3PS-K 3PC Tri-Clamp Pneumatic Actuated Ball Valve
The 3 piece pneumatic actuator ball valve design allows for the center part of the valve containing the ball, stem seats to be easily removed from the pipeline. This facilitates efficient cleaning of deposited sediments replacement of seats and gland packings, polishing out of scratches on the ball. all this without removing the pipes from the valve body. The design concept of a three piece valve is fot to be repairable.
COVNA also offer manual 3pc tri-clamp ball valve, electric 3pc tri-clamp ball valve.

COVNA 3PC 2 Way Tri-clamp Ball Valve with pneumatic actuator
- The resistance coefficient of the fluid is equal to that of the same length of pipe
- Simple structure, small volume and light weight
- It is tight and reliable. The sealing surface material of ball valve is widely used in plastic, with good sealing performance. It has also been widely used in vacuum system
- It is easy to operate and fast to open and close. It only needs to rotate 90 ° from full open to full close, which is convenient for remote control
- It has a wide range of applications, ranging from small diameter to several millimeters and large diameter to several meters, from high vacuum to high pressure
