Effective Flood Prevention
The Double Flap Backwater Valves (double non-return valves) have numerous advantages to other similar double backflow valves and are ideal in situations where greater protection against backflow is required.
Two independent protecting covers
These are beneficial during flow because the pressure affecting the first flap is not immediately transferred to the other.
To service, the stainless steel screws are simply removed giving access to the flap and gasket.
Fits UK Pipes
The valve comes in standard sizes to fit UK pipes at 110, 160 and 200mm
Meets Regulations
The economically priced valves are EN certified and meet UK regulations.
Protects against rodents
The flap's guard and gasket are designed to protect against damage by rodents and block their entry.
Ensures a smooth flow
They have a smooth interior surface to prevent any sediment collection and to ensure smooth flow.
Independently Lockable Valves
The valves feature a independently lockable levers to manually close the valves in both directions, this allows fast evaluation of the proper operation of both valves.
