Stainless Steel Trieccentric Butterfly Valve with pneumatic actuator

If the stem axis deviates from the disc center and the body center at the same time, and the rotation axis of the valve seat has a certain angle with the channel axis of the valve body, it is called three eccentric butterfly valve.

COVNA HK59-D-G Series butterfly valve is triple off-set design which has aAdvantage of light weight, compact design and costeffective, low operation torque and can replace traditional gate valve, globe & ball valve in most of industries application
