-Resilient or metal seated.
- Retainer or Retainer Less Design
- Round, Full Lug or Double Flange
-Light-weight & compact design.
-Optional plug disc.

SPRING SELECTION GUIDE
-Standard Spring Suitable for the line pressure of 0.298MPa through 0.89MPa without any pressure loss and the upward flow direction of vertical installation.
-Low Coil Spring Ideal for gas with the line pressure of 0.1MPa and under.
-High Coil Spring Suitable for the line pressure of 0.88MPa.

THE SEAT DESIGN OF DUAL PLATE CHECK VALVE
-No leak, no distortion seals Seat design can be furnished with the resilient seal materials that provide tight seals without leakage and metal seals with minimum leakage.

Advantage
-Face-to-face dimensions for Dual Plate Wafer Check Valves are about one fourth of a Swing Check Valve.
-Weight is as little as about 20% of the corresponding Swing Check Valve due to the compact design.
-Dual Plate Wafer Check Valves have a spring design to close valves more efficiently when the back flow occurs to reduce the water hammer.
-These valves have the lower pressure drop than Swing Check Valves because of little friction resistance.
-Dual Plate Wafer Check Valves are less expensive than Swing Check Valves because of the lightness and compact design. These valves are also easier and less expensive to install and maintain because of fewer piping supports and easy handling for installation.
-Because Dual Plate Wafer Check Valves are flangeless, they are installed between flanges.
-Normal installation method for horizontal flow is with the hinge pin in vertical position.
-Installation is available for both horizontal and vertical piping.
