Bi-directional Sealing Metal Seated Butterfly Valve is a high performance butterfly valve used in the condition of two-directional sealing service ,such as circulating water system ,heat-supply pipe network etc .It combined the benefits of ball valve and butterfly valve ,and replace the triple offset butterfly valves in most of situation.
BENEFITS
1.Designed with bidirectional sealing structure,the installation of the bidirectional rotary ball valve will not be restricted by the direction of the fluid.
2.Since the metal seated butterfly valve is offered with self-sealing device,reliable sealing performance can be realized under the pressure from medium.
3.Tight sealing ,especially suit for the non-clean medium which include the particle water .
4.Really metal seated butterfly valves ,not the multilayer sealing tructure of triple offset butterfly valves.
5.Ball valve's sealing performance ,butterfly valve 's dimension
6.Large size can be made ,the max size can reach up to DN3000.
7.Easy to operate and maintain .
