Description Parameters Size Chart Application

Feature:

1.The valve sealing three-eccentric structure, valve seat and butterfly plate almost no wear and tear, with more tightening of the sealing function concept.

2.Selection of stainless steel ring with a metal seal and sealing the dual advantages of flexibility, both in the case of low temperature and high temperature, all have excellent sealing properties, resistant to corrosion, long service life and so on.

3. Dish plate sealing surface using cobalt-based alloy welding, sealing surface wear resistance and long service life.

4.Large-sized butterfly plate with lattice structure, high strength, over-current area, flow resistance small.

5.This valve has bi-directional sealing capabilities, installation, media flow is not restricted, but also from the impact of spatial location can be installed in any direction.

6.Drives can be multi-bit (rotated 90 ° or 180 °) to install, easy to use
