Non Return Isolating Ball Valves with Strainer

Non Return Isolating Ball Valves With Stainer by AVG

The NRI's from AVG is the perfect twin function valve widely used when installing appliances. The non-return & isolating valve provides two important functions;

  1. It is an isolating valve isolating the incoming mains water from the appliance, a typical usage would be the installation of a hot water tank allowing easy service of the hot water heater without isolating the properties water supply completely.
  2. It is a non-return valve prevents water returning back up the supply line.
  3. The NRIBVS range of non return isolating valves incorporate a line strainer which is designed to protect any down stream valves and or equipment. The removable strainer prevents grit and debris from entering the line.
