Uni-Flange Ball Valve
August 1, 2002
Webstone Co.'s ISOLATOR Uni-Flange Ball Valve features a solid brass body and incorporates a flange connection on one end that fits most circulating pumps in use today. This valve eliminates the need for a set of flanges, pipe nipples and ball valves, and prevents electrolysis and galvanic corrosion by isolating the pump from the piping system.
