flanged butterfly valve

The hard sealing butterfly valve used triple eccentric structure, this design has the function of closing and tightening when closed. The triple eccentric butterfly valve disc can bear pressure in both directions, with excellent sealing performance and zero leakage. After opening, the sealing surface is completely out of contact and protects the sealing surface from damage. The body valve seat ring is surfacing by stainless steel, which reduces the direct contact of the valve seat with the medium, reducing the degree of erosion of the valve seat and extending the service life of the valve seat.

Double flanged butterfly valve ues the ductile iron materials with good casting performance, low cost, convenient production Pneumatic actuator butterfly valve use pneumatic actuator more easy maintenance and good adaptability to the environment,the output power is large,and fast opening and closing speed.
