Iron Casting ANSI End Flange Water Non Return Disc Swing Check
Valve
Application
Swing Check valves are used in pipes under pressures between
PN1.6~16.0Mpa (class150 ~ 2500lb), working temperature -196℃~ 60℃.
They are used in industries include oil, chemistry, pharmaceutical,
fertilizer, and power generation to prevent the backward flux of
the media.
Swing Check Valve is used to prevent back flow in the line. Flow is
in a straight line through the valve resulting in minimal pressure
drop. The disc swings into the open position as the media flows
through the line. Back pressure in the line holds the disc in the
closed position. Swing check valves may be installed in horizontal
or vertical lines, but must be installed in proper relation to the
media flow as indicated by the flow direction arrow marked on the
body.
Features

3. Two torsion spring are used excreting on each of thee pair valve
plates. Which close the plates quickly and automatically.
4. The quick - close action prevent the medium from flowing back
and reduce water hammer pressure.
5. Can be installed both horizontally and vertical descending on
pipeline.
6. Safe and reliable in operation, high interference - resistance.
