Handle flanged butterfly valve

about butterfly valve:

Butterfly valve, is a simple structure of the control valve, it can be used to control the flow of air, water, steam, corrosive media, mud, oil, and other types of fluid. It is mainly used for cutting and throttling in pipelines. Butterfly valve opening and closing parts is a disc shaped disc, in the valve body around its own axis rotation, so as to achieve the purpose of opening and closing or regulation.

Flanged butterfly valves are free from fluid leakage. They can be installed where space is limited, unlike other large-sized valves. These valves are used in shut-off and throttling fluid flow applications. These valves operate by making a quarter turn which makes their operations very fast.

Product advantages:
        1. 1.Heavy body,the thickness of valve body meets the requirements of GB26640 to ensure bearing strength.
        2. 2.epoxy coating, spray thickness up to 250um.Strong adhesion.
        3. 3.import EPDM rubber material. 50 percent rubber content, Stable and small torque, zero leakage after open and close more than 10000 times .
        4. 4.Wider rubber seat,wider contact surface with flange.better sealing performance.
        5. 5.Each valve will be wasted by ultrasonic cleaner before packing, Remove dirt and granularities from valve body. Prevent the valve itself from coordinating the media in pipes.
