Structure
The series of multi-layer metal-to-metal butterfly valve is the new one with long lifetime and energy economized. The seat is designed according to the three-dimensional principle, the compatible to soft sealing and metal multi-layer structure, with best machining and advanced technology. And the valve is mainly made up of body, disc, multi-layer seat, staminate actuator.
Features
The butterfly valve has the ideal sealing track because of following three-eccentric principle, without friction and interference between sealing sets, and also adopts the proper material, which make the butterfly valve have the sealing ability, corrosion resistant, temperature resistant , and wearing resistance. The main futures as bellow:
a.Small open torque, flexible, content, lobar saving and energy economized.
b.Three-eccentric structure to make the disc more and tighter. With reliable sealing ability and no leakage.
c.High pressure resistant, corrosion resistant, wear resistance long lifetime.
