- Eliminates galvanic corrosion
The Isolator is a uni-flange ball valve that isolates a circulator pump, allowing virtually no air into the system during pump replacement or service. Its innovative design combines multiple components into a single forged brass body that saves time, labor and space. The Isolator has revolutionized the installation of circulator pumps and has evolved into the largest flanged ball valve program in the industry today, featuring patented technology with further patents pending. Designed for use with water, oil, glycol mix in residential or commercial residential plumbing, commercial plumbing, heating systems. Refer to specification sheets for additional technical information. All Webstone products are backed by a limited lifetime warranty.
