How do you install a dual plate check valve?
Dual Plate Check Valves must be installed with the arrow in the direction of the normal flow. This must be checked carefully before installing the valve. Placing a check valve in the opposite direction to the flow will prevent the disc from operating in the intended manner.

1. Small in size, light in weight, compact in structure, easy in maintenance.
2. Two torsion springs are used excreting on each of the pair valve plates. Which close the plates quickly and automatically.
3. The quick-close action prevents the medium from flowing back and eliminates water-hammer effect.
4. This valve is short in length, so that it is rigid and easy to mount.
5. It is easy to install on pipeline which is laid horizontally or vertically.
6. This valve is tightly sealed without leakage under the pressure water test.
7. Safe and reliable in operation, high interference-resistance.
8. The face to face dimensions are in accordance with API 6D.
The stem of the valve should be perpendicular to the horizontal level when the valve is mounted on horizontal pipeline. For vertical installation the direction of flow should be downward.
