Product Overview

FLH77X type clip check valve produced by our factory is composed of valve body, valve valve, valve stem and spring. Because the valve closes are short and the propare has spring loading, the water hammer can be significantly reduced. The valve is mainly applied to the network of water supply and drainage pipe in urban, industrial and high-rise buildings. Because of its structure length, the short check valve is most suitable for the installation where the installation position is limited.

Wafer Check Valve Design:

1. Body: Ductile iron, Cast iron, Carbon steel, Stainless steel
2. Disc: stainless steel, Ductile iron
3. Stem: Stainless steel
4. Seat: EPDM, NBR, VITON
5. Face to face dimension:Standard

Features:
1. Small in size, light in weight, compact in structure, easy in fix.
2. Two torsional springs are installed on each of dual valve plates, result in close the plates quickly and automatically.
3. The quick-close action prevents the medium from flowing back and eliminates water-hammer effectively.
4. Safe and reliable in operation, high capability of resisting interference.
5. It is easy to install on pipeline which is laid horizontally or vertically.

Note: 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.
