Highlight: Swing Check Valve
Product introduction:
Check valve is also known as back-pressure valve or non-return valve, it is to prevent the pipeline medium flow back.
The opening and closing parts are opened or closed by the medium
flow and force to prevent the medium from flowing back.Swing check valve is a type of check valve, the internal use of
rocker arm swing type structure,This kind of valve is widely used in chemical industry, metallurgy,
pharmaceutical and other fields, generally should be installed
horizontally in the pipeline.

Product features:
1, swing check valve is suitable for the occasion of large
diameter, installation position is not restricted, usually
installed in horizontal pipeline, swing check valve is suitable for
the occasion of large diameter, fluid resistance is generally less
than the lifting check valve,
2. Swing check valve rocker arm and disc connection using spherical
connection structure, so that the disc in the range of 360 degrees
have a certain degree of freedom, there is appropriate trace
position compensation.
3. Swing check valve with built-in rocker arm swing structure, all
valve opening and closing parts are installed in the valve body, do
not penetrate the valve body, in addition to the flange part with
sealing gasket and sealing ring, the overall no leakage point,
eliminate the possibility of valve leakage.
