Anti-Backflow Drain Valve – Vertical

Anti-Backflow Drain Valve – Vertical Technical Data Sheet: download-pdf

The Vertical Anti Backflow Drain Valve is designed to sit inside the bottom outlet pipe of a drain outlet, and close off the pipe to prevent waste water returning into a gully, and more importantly into the room.

A neoprene rubber gasket is sandwiched inbetween the top plate of the valve and the lower plate creating a water tight seal. The lower plate is fully welded onto the outlet pipe prior to bolting on the valve.

The vertical valve has a ∅70mm hollow polypropylene ball, which is floats up and down according to the water flow. If a backflow of liquid arises, the ball get forced upwards closing off the pipe.

The stainless steel material of the valve is bead blasted for a smooth, corrosion resistant surface finish.

The valve is available in 2 outlet sizes to accommodate the outlet pipe sizes; ∅110mm and ∅160mm.
