China Electric Operated Butterfly Valve Manufacturers, Suppliers, Factory

Cryogenic gate valve is suitable for methane, liquid natural gas, ethylene, carbon dioxide, liquid ammonia, liquid oxygen, liquid nitrogen, liquid hydrogen and other low temperature media.

Non return butterfly check valve is a one-way valve, is also an automatic valve, non return butterfly check valve only allows media to flow in one direction, and prevent media backflow. Non return butterfly check valve works automatically. Under the action of medium pressure flowing in one direction, the valve disc opens and the medium passes through; When the medium flows in the opposite direction, under the action of medium pressure and the self weight of the valve disc, the valve disc closes, thus cutting off the medium flow.

1. The double flow direction can bear pressure to realize the installation mode without flow direction restriction. 2. The design of all metal seal, the seat and sealing ring adopt steli alloy surfacing technology to solve the problem of poor sealing performance of butterfly valve under severe working conditions such as high temperature, high pressure and low temperature. triple eccentric butterfly valve can withstand pressure up to 2500 pounds, and the temperature resistance is as low as -196 ℃ to 850 ℃, the seal reaches 0 leakage and the control ratio is up to 100:1. 3.The triple eccentric butterfly valve seat and valve body are designed separately, and the valve plate and sealing ring are designed separately. The products can be matched and interchanged. The whole valve will not be scrapped because of the seal wear problem. triple eccentric butterfly valve can be used normally only by replacing the valve seat and sealing ring, thus reducing the use cost.

Stainless steel butterfly valve, also known as stainless steel flap valve, adopts three eccentric multi-layer metal hard seal structure; Stainless steel butterfly valve is widely used in metallurgy, electric power, petrochemical, water supply and drainage and municipal construction industries where the medium temperature is ≤425℃ On the pipeline, it is used for adjusting the flow rate and carrying and breaking the fluid. The stainless steel butterfly valve adopts a triple eccentric structure. The valve seat and the sealing surface of the disc plate are made of different hardness and stainless steel, which has good corrosion resistance and long service life.

Butterfly control valve is a simple regulating valve that can be used for switching control of low-pressure pipeline media; it can be used to control air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. It mainly plays the role of cutting off and throttling on the pipeline.
