Webstone Pump Flange Valves

Webstone Isolator Flange Valves are the most convenient, fast and effective way to isolate circulator pumps. Each flange valve is a universal pump flange and a ball valve in 1 piece. Some models also include a hi-flow drain valve on the side with garden (drain) hose connection. Compatible with all standard circulator pump flange sizes (including the Taco "00" series). Manufactured from forged brass for longer life and greater durability. Webstone Isolators are available in a large variety of connection types and sizes, with or without drain valves. Flange valves are sold in pairs and include a set of (4) bolts, (4) nuts and (2) optional T-shaped handles for installation in areas with limited access.

For heating applications only.
