Eccentric-ball Butterfly Valve

Description

The traditional butterfly valves can’t be used for media with high pressure(normally not higher than 2.0MPa);and traditional valve is sensitive to media with impurities,the impurities may plug in or twine the sealing face,and then result the butterfly valve can’t open or close or result the valve lost sealing function,or damage sealing face.

Eccentric-ball butterfly valve solves traditional butterfly valve’s weakness mentions above.

This eccentric-ball butterfly valve uses a special sealing method:eccentric sphere to shaft-direction floating tube shape end face.This method completely solves weakness of traditional butterfly valve.This eccentric-ball butterfly valve structure dimensions is same traditional butterfly valve,manufacturing cost is almost same,and occupy small area,convenient to open and close,excellent sealing performance,have long lasting working life,and applicable for media(like water,oil,gas,etc.,) with high pressure,high flow rate,high concentration impurity,it is an ideal updated and substituted valves.
