Expansion butterfly valve, butterfly valve

Features:

1. Novel design, reasonable, unique structure, light weight, convenient operation, rapid opening and closing; 2. In addition to regulating and intercepting the function of intercepting the flow, it also contains the function of thermal expansion and contraction caused by the temperature difference of the compensation pipeline; 3. The design provides convenience for installation, replacement and maintenance;

4. Expandable seat can reduce the wear of valve plate and seat;

5. It has ultra-low torque demand, low actuator energy demand, large sealing contact area, and long valve life.

6. Proven superiority for corrosive materials and dry bulk solids.

Application；

Expansion butterfly valves are widely used in industries such as petroleum, chemical engineering, metallurgy, power generation, and water treatment. In the petroleum industry, expansion butterfly valves are used to control the flow and pressure in oil and gas pipelines; in the chemical industry, they are used to control the flow of various chemical media; in the power industry, they are used to control the steam flow of steam turbines; in the water treatment industry, they are used to control the flow and pressure of water supply pipelines. In summary, expansion butterfly valves, as a common type of pipeline control valve, play an important role in industrial production.
