Branch Valve - Servicing / PRV / Double Check
Part Number: BRV
Product Overview
The Branch Valve has been designed specifically to comply with the new Water Regulations – see below. The assembly consists of a full-bore Servicing Valve and low head-loss Double Check Valve. Flat-faced connectors allow direct connection to the pipe without the need for sealants or additional adapters. Normally Solder Unions – more reliable than compression - are used but connections to any pipe materials system are available.
Flat-faced union connectors with EPDM washers allow valve to be easily installed to new or existing pipes without the need to spring pipes apart. The unions enable the handle to be aligned and the assembly is demountable.
Oversize, high-flow Cartridges provide exceptionally low head-loss characteristics – see model ED132 datasheet.
The Branch Valve can be installed horizontally or vertically. As a modular design, additional components can be added at the factory, such as a Strainer model BRFB (see Filterball data sheet), Pressure Reducing Valve model BRPRV (see PRV536 and PRV1300 data sheet), secondary Water Meter (model BRMV) or Pressure Reducing Valve and secondary Water Meter model BRPMV.
