160mm Drainage Non Return Valve (double flap)

Model:  PTE627D

160mm Drainage Non Return Valve (double flap)

-The device has two independent covers, which is beneficial during reverse flow because the pressure acting on the first cover is not transferred to the second one.

-The Non Return Valve is equipped with a manual closing lever. Moving the lever from an upright position to flat/flush against the product completely stops the reverse flow of sewage.

-The interior of the device has a smooth surface and is properly profiled, preventing the accumulation of sediments and ensures full, undisturbed flow of sewage
