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.

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.
