is a new product developed by our company on the basis of double eccentric flange butterfly valve,which is easy to fail in axial seal and short in service life.
Features:
Butterfly valve has the advantages of double eccentric flange type butterfly valve.
Adopt the anti-mud sand sealing structure to ensure the axial non-leakage,stainless corrosion, not stuck and other phenomena, prolong the service life ofthe valve.
Application of sand-proof flange butterfly valve: in petrochemical, food, medicine,textile, paper, water and electricity, ship, water supply and drainage and other corrosive, non-corrosive medium pipeline, as closure and throttling, more suitable for the high sediment content of the Yellow River drainage pumping station pipeline.
- The unique design of three-way eccentricity makes the sealing face free of friction transmission and prolongs the service life of the valve.
- Elastic seal produced by torque
- Clever wedge design makes the valve more and more closed and tight automatic sealing function, sealing surface between the compensatory, zero leakage
- Small size, light weight, light operation, easy to install
- Pneumatic and electric devices can be configured according to the requirement of users to meet the needs of remote control and program control
- Replacement parts material can be applied to various media, and lining anti-corrosion (lining f46 gxpp poetc.)
- Diversification of continuous structures: butt welding, flange
The butterfly plate of the sand-proof flange butterfly valve is installed in the diameter direction of the pipe. Within the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When rotating to 90°, the valve plate isfully open
