DUAL PLATE WAFER TYPE CDP5


• Most compact in width; needs minimal space between 2 flanges.
• Lighter in weight – so can be easier to use between plastic flanges.
• Water hammer effect is minimized as closure of valves is not dependent on back pressure or flow.
• Dual Spring on each flap ensures that the valve opens and closes at minimal pressure.

SPRING LOADED CHECK VALVE CSP3


• Low weight plastic disc helps reduce the pressure drop and needs minimal pressure to actuate it.
• Suitable for both horizontal and vertical lines.

SWING (FLAP) TYPE CSW2


• Maximized bore area to minimize the pressure drop.
• Nitrile seal on flap to give drop tight seal even at low reverse pressure.
