THE ISOLATOR Uni-Flange Ball Valve is now available from Webstone Co. It features a solid brass body and incorporates a flange connection on one end that fits most circulator pumps. The other end has either threaded or sweat connections available in a multitude of sizes. This valve eliminates the need for a set of flanges, pipe nipples and valves by incorporating an all-in-one design. It also prevents electrolysis and galvanic corrosion by isolating the pump from the piping system and keeping dissimilar metals from contacting each other. www.webstonevalves.comWebstone Company.
