4 Inch Lug Double Eccentric Butterfly Valve PN20 A351 Cf8m 150Lb 100mm PTFE Seat Double Offset Butterfly Valve

 

VERVO High performance butterfly valve is a new butterfly valve designed on the basis of advantages absorbed from several different structures of butterfly valves. The seal surface of the disk is spherical arc, and the seal structure achieves a real dynamic seal through the system pressure, so it has excellent cut-off performance and durability. Its advantages are small size, light weight, owning a wide range of manufacturing, easy to repair and maintenance.

  1. The double soft seal design of the high performance butterfly valve gives it zero leakage performance.

  2. The high performance butterfly valve can get the disk detached from the seat quickly when the valve is opened,greatly eliminating the unnecessary over extrusion and scraping between the disk and the seat, reducing the opening resistance torque as well as the wear, and increasing the seat life.

  3. The seat design of the high performance butterfly valve adopts different non metallic materials according to different customers to meet different working conditions. It can also use both soft seal and metal seal to make the valve fire seal by creating a double seal structure.

  4. The external blow out proof stem of the high performance butterfly valve is safe and reliable, and conforms
