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.
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
