The sealing performance of the seal is good, but it is not resistant to high temperature, easy to wear, and has poor mechanical properties. Such as: rubber; tetrafluoroethylene, etc. The soft sealing seat is made of non-metallic materials and has certain strength, hardness and temperature resistance. The sealing performance is good, and zero leakage can be achieved, but the service life and temperature adaptability are poor. Hard seal: The two sides of the sealing pair are made of metal materials or other hard materials, which is called "hard seal". This...

As a   Butterfly Valve Supplier , share with you. A butterfly valve is a valve that uses a disc-type opening and closing member to reciprocate about 90° to open, close and adjust the fluid channel.

"Where are the butterfly valves used?" "Butterfly valves are generally used for various water fluids, such as domestic water, fire water, process water, circulating water, chilled water, sewage, etc.. Butterfly valves can also be used for some powder materials. Butterfly valves cannot be used To adjust the flow rate. It can be used for automatic switching valves." "On official roads with large diameters, butterfly valves are generally used to control flow. For example, on DN1000 pipelines, if gate valves or stop valves are used, how big the valve should be Ah. But butterfly valves are rarely us...
