Flanged Cast Iron Butterfly Type Buffer Check Valve OEM Support

Butterfly Type Buffer Check Valve Product Overview

Butterfly buffer check valve is mainly used at the outlet of water pumps in industrial water supply and sewage treatment plants to prevent medium backflow in the pipe network. It automatically eliminates destructive water hammer to ensure that the water pump and pipeline are not damaged. The valve is mainly composed of valve body, valve disc, buffer device and micro-adjusting valve. The product has the characteristics of novel structure, small size, small fluid resistance, stable operation, reliable sealing, wear resistance, good buffering performance, etc. It is the best product for industrial water and urban sewage discharge.

Materials of main parts

The working principle of the butterfly check valve

When the medium flows through the valve body channel, the medium pressure is greater than the spring force, pushing the two butterfly plates open, the valve opens, and the medium flows; when the medium stops flowing, due to the spring force, the two butterfly plates are forced to reset, the valve closes, and the medium is prevented from flowing back. Butterfly check valve structure diagram Butterfly check valve is also called double-flap double-flap check valve. Its sealing surface can be welded with wear-resistant materials or lined with rubber. It has a wide range of applications and reliable sealing. Butterfly check valve is an automatic valve and does not require manual operation. This valve is usually used in pure pipelines, as well as industrial, environmental protection, water treatment, and high-rise building water supply and drainage pipelines to prevent medium backflow. Prevent medium from flowing in reverse.
