50417HV 2" High Velocity Sweat Isolator with Drain

Simplify circulator pump installation and maintenance with the Webstone 50417HV High Velocity Isolator Uni-Flange Ball Valve with Drain. Engineered for hydronic heating and cooling systems, this innovative valve combines multiple components into a single compact assembly, reducing installation time, minimizing potential leak points, and improving system serviceability.

Constructed from heavy-duty forged brass, the 50417HV features a full-port ball valve design for maximum flow capacity and minimal pressure loss. Its integrated high-flow drain allows fast purging and draining from either side of the pump, while the high-velocity uni-flange connection accommodates standard and high-velocity circulator pumps. A conical inlet design helps reduce turbulence and optimize system performance.

The Webstone 50417HV is designed to isolate pumps quickly for maintenance or replacement without draining the entire system, saving labor and downtime. Additional features include a blowout-proof stem, adjustable packing gland, PTFE seats and seals for dependable operation, and corrosion-resistant construction that helps prevent galvanic corrosion and electrolysis.
