Ball check valves for heavily contaminated water 65mm

The 508 check valve consists of a self-cleaning ball that is lifted by the liquid and guided to a side seat, completely out of the way.
This system provides a full flow, even with loaded liquids, without risk of blockage.

– Vertical and horizontal operation (position of the ball above the axis of the pipe)
– Quiet, robust
– Non-corrosive material
– Sealing ensured by an elastomer seal attached to the seat

Can be mounted vertically or horizontally, when horizontal there is almost 0mm opening pressure.

Opening pressure in mm for vertical mounting different sizes
25mm is the height 25mm
32mm is the height 30mm
40mm is the height 160mm
50mm is the height 160mm
65mm is the height 170mm

When mounted horizontally, there is almost 0mm opening pressure.
