Webstone H-81417WHV is a 2" lead free isolator for high velocity pumps: a full port forged brass Uni-Flange ball valve with a press connection, a detachable rotating flange and a multi-function hi-flow hose drain.
It isolates the pump for easy replacement and helps prevent electrolysis and galvanic corrosion. A snug-fit snap-ring secures the rotating flange, giving more control over positioning during installation, and the flange has a conical inlet to minimize turbulence. The multi-function drain lets the isolator drain from either side of the pump. It has a blowout-proof stem and an adjustable packing gland, comes with nuts and bolts, and is certified to NSF/ANSI/CAN 61 and 372 and NSF/ANSI 14.
Webstone says it fits virtually any standard circulator pump. Before ordering, confirm the pump flange matches, that the piping is 2" for a press connection, and that you have suitable press tools. It is rated to 250 PSI CWP and 250°F.
