The full price of electric butterfly valve is lower than that of spesak Fushan valve

  1、 Introduction to electric wafer butterfly valve d971f electric wafer butterfly valve is composed of Chr angle stroke electric actuator and straight through cast butterfly valve body
The electric actuator has strong function, small volume, light and pleasant, reliable performance and simple matching
The valve body of electric switch butterfly valve has large flow capacity
For normal temperature and clean media, the valve plate and soft seal (rubber ring and tetrafluoro ring) can be selected to reduce leakage (up to zero leakage)
Under high temperature and high pressure conditions, the three eccentric hard seal structure can be selected, with one & ldquo; U” The precision elastic sealing ring is in three-dimensional eccentric contact with the polished butterfly plate
It solves the problem of traditional eccentric butterfly valve in opening and closing 0 & deg; ~ 10° The instantaneous sealing surface is still in the disadvantage of sliding contact friction, so as to realize the effect that the sealing surface of the butterfly plate is separated at the moment of opening, and the sealing effect is closed at the moment of closing contact, so as to prolong the service life and achieve the best sealing performance
