160mm Double Flap Backflow Valve
Double Flap Backflow Prevention Valve to fit 160mm (DN 150) waste/sewage pipe
This valve prevents backflow automatically and meets EN13564-1:2001. The two valves open to the full diameter of the pipe to reduce the possibility of blockage, and the lid can be removed for maintenance if necessary. A closure lever allows the valve to be locked shut if required. This valve is suitable for rainwater overflows, foul and stormwater drainage. It is an effective anti-flooding device when installed on properties susceptible to flooding from rivers or in areas prone to repetitive backflow of sewage.
These valves can be locked closed independently and serviced seperately.
Material : Polypropylene, with stainless steel valve plate and rubber seals
