Centric Construction Butterfly Valve
Centric Construction Butterfly Valve
Centric Construction Butterfly Valve is a kind of valve for controlling fluid switch and regulating flow, its valve plate rotates in the center of pipeline, and the sealing surface is arranged symmetrically with the center of valve body. It is simple in structure, small in size and light in weight, and is suitable for low pressure and large diameter occasions.

Features And Benefits
The steering center of the butterfly plate is on the centerline of the valve body and the sealing area of the butterfly plate. when closing, the outer cut sealing surface of the butterfly plate will squeeze out the synthetic rubber seat, and produce elastic deformation on the seat to ensure the sealing of the butterfly valve from the surface.
Compact And Light
Butterfly valve assembly space is small, light weight, easy to install and maintain, suitable for working conditions with limited space.
Good Sealing And Long Service Life
Good sealing effect, long service life, adapt to a variety of fluid control occasions.
Lightweight And Low Torque
Light structure design, low operating torque, reduce operating costs and energy consumption.
Soft Seal
Soft sealing design ensures high sealing performance, adapting to various working conditions.
