Product Introduction

Double eccentric soft seal  butterfly valve is a shut-off bicirectional valve with a double offset ofthe disc. 
lt has good fluiccontrol characteristics and closing sealing performance, and is widely used in food, medicine, chemical, petroleum.electric power, textile, paper and other industries .


Working Principle

The eccentric principle is that the stem shaft is both deviated from the valve body center (a), also deviated from the seat (b)The double eccentricity effect allows the butterfly plate to  quickly  detach  from  the  valve  seat  when  the  valve   is  openedGreatly  eliminates unnecessary excessive squeezing and scraping between the butterfly plate and the valve seat, reduce:the valve opening torque, reduces valve seat wear, and improves the service life of the valve seat .


Parameters


Soft seal butterfly valve-Sealing ring on the body

On the basis of the disc seal butterfly valve, derived body seal structure butterfly valve - the  sealing  ring  is fixed  on the valve  body. Thestructure  also  has  good fluid  control characteristics and closing sealing performance .

1. The automatic adjusting elastomer seat is fixed to the body
