Double eccentric two-way sealing butterfly valve

product description:

Butterfly valve has simple structure and small volume. Light weight, low material consumption, small installation size, small driving torque, simple and rapid operation, and also has good flow adjustment function and closing and sealing characteristics. In the application field of large and medium caliber, medium and low pressure, the butterfly valve is Leading valve products. It is widely used in power, metallurgy, chemical, urban water supply, drainage and other pipelines to cut off or adjust the flow of media.


Technical Parameters:

Nominal diameter: DN100~ DN4000mm

Nominal pressure: PN0.6~2 5MPa

Use medium: oil, water, gas, etc.

Operating temperature: normal temperature

Drive mode: worm gear drive, pneumatic drive, electric drive, hydraulic drive

Design standard: Design and manufacturing standard GB/T12238 "Flange and wafer connection elastic sealing butterfly valve", flange connection standard GB/T17241.6 "Integral cast iron flange" or GB/T9113 "Integral steel pipe flange", Structural length standard GB/T12221 "Metal valve structural length", test and inspection standard GB/T13927 "Industrial valve pressure test"


Features:

1. Two-eccentric structure: It has a sealing function that is tighter and tighter as it closes. The sealing pair can be opened and closed instantly, which reduces the friction in the opening and closing process and extends the service life of the valve;

2. Reliable sealing: stainless steel and rubber are selected as the sealing pair material, which has reliable sealing and long service life;

3. New technology of surfacing welding: The sealing surface of valve seat adopts the new technology of surfacing stainless steel alloy, and the sealing surface of valve seat is not worn during use;

4. The sealing ring is fixed and reliable: the rubber sealing ring is fixed on the valve plate through the pressure plate and the screw. The sealing ring adopts a T-shaped round high hardness solid rubber ring, integrally vulcanized, and seam-connected high-quality synthetic rubber. ;

5. Convenient maintenance and replacement: After the rubber seal ring is worn out, the seal compensation can be adjusted by adjusting the adjustment screw on the butterfly plate to achieve any adjustment of its seal specific pressure. When it is really necessary to replace the butterfly plate sealing ring, it is very convenient to directly replace the valve in the pipeline without dismantling the valve (DN≥800).
