The Branch Valve has been designed to specifically to comply with the Water Regulations. The assembly consists of a full-bore Servicing Valve and low headloss 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 the 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. The Branch valve can be installed horizontally or vertically.


The main supply and distributing pipes serving several dwelling units such as in a block of flats where contaminated water might pass from one flat to another, industrial premises, schools, offices, hospitals.
