These valves have high functional reliability because the rubber lined disc ensures tight closure, no rotating parts, and no extension through the valve body wall.
ince all wetted parts are rubber lined, they have high corrosion resistance and wear resistance.
Swing check valves are fluid controlled. This means that their functions cannot be manipulated from the outside. At low flow rates - which may occur when operating variable speed pumps - the valve disc remains stable in its position and does not vibrate.
The valve adopts full diameter linear streamline design, and its flow resistance is 45% lower than that of different types of check valves. Generally, the key factor supporting these swing check valves is the short fluid stability distance required. The distance between a nominal size upstream and downstream of the valve is sufficient for reliable operation.
The valve can be installed in horizontal or vertical position. Valve bodies made of ductile iron are available in nominal sizes from 25 to 300 and are designed for a nominal pressure of 16 bar.
