Hydraulic slow-closing butterfly check valve is mainly used in the pump outlet of industrial water supply and sewage treatment plants to prevent the backflow of media in the pipe network, automatically eliminate destructive water hammer and ensure that the pump and pipeline are not damaged. Hydraulic slow-closing butterfly check valve is mainly composed of valve body, valve flap, buffer device and miniature adjustment valve. Hydraulic slow-closing butterfly check valve has novel structure, small volume, low fluid resistance, smooth operation, reliable sealing, wear resistance and good buffer performance. It is the best product for industrial water and urban sewage discharge.
PTFE seat Stainless Steel Lug butterfly valve Widely used in metallurgy, chemical industry, building materials, power station, glass and other industries in the ventilation, environmental protection engineering of dust-containing cold air or hot air gas pipeline, as a gas medium to regulate the flow or cut off device usually by the angle-stroke electric actuator (0 ~ 90 ° part of the rotary) and butterfly valve as a whole through mechanical connection, after installation and commissioning together.
1.Valve seat over 50% rubber content, extended durability by 1-2 years； 2. International standard design, special products for International important projects；
