Flexible Rubber Butterfly Valves Replacement of Stainless Steel Butterfly Valves Cost-effective Valve Absorbs Noise/Vibration
Flexible Rubber Butterfly Valves
Description:
Flexible Butterfly Valves (KSFD,KSD), the latest items, have been patented nationally(NO.ZL96112556.X) and acclaimed unanimously after the carefully scientific and technological assessment in the Provincical Administration. Our company enjoys the exclusive patent of them.
Characteristics:
Being heat-proof,acid-proof,alkali-proof,oil-proof, they are able to replace the flexible rubber joints and other types of valves.
Product Advantages:
1)Small in size and light in weight and maintaince. It can be mounted whereever needed.
2)Simple, compact structure, quick 90 degree on-off operation.
3)Disc has two-way bearing, perfect seal, without leakage under the pressure test.
4)Flow curve tending to straight-line. Excellent regulation performance.
5)Various kinds of materials, applicable to different medium.
6)Strong wash and brush resistance and can fit to bad working condition.
7)Center plate structure, small torque of open and close.
8)Long service life. Standing the test of ten thousands opening and closing operation.
9)Can be used in cutting off and regulation medium
KSFD,KSD Flexible Butterfly Valves are widely used in the areas of chemical industry, sanitation, ironing, paper-making, water-supplying, brewing, draining, construction and so on.
