Iron Casting ANSI End Flange Water Non Return Disc Swing Check Valve
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.
1. Short in length, installed easily.
2 .Small and light, tightly sealed, easy in maintenance.
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.
