Webstone, the original designer and builder of The Isolator Uni-Flange Ball Valve was issued a U.S. patent for its Isolator uni-flange ball valve technology on December 3, 2003. Documentation has been filed to include worldwide patent rights for this product. Since its original introduction, the Isolator family of valves has revolutionized the radiant and hydronic industries by providing an easier, faster and lower cost method of installing and servicing circulator pumps. Webstone remains on the technology forefront with more new and innovative products scheduled for release in their 50th anniversary year of 2004.

Designed for residential and commercial use with water or oil. The forged brass body and flange provide strength and versatility for any application where a pipe and flange meet. This approved Webstone valve features a solid hard chrome plated brass ball with reinforced Teflon® seats and a blowout proof stem sealed with Teflon® (PTFE) and an adjustable packing gland. Vinyl coated stamped steel handle. Ideal for use with circulating pumps. The solid brass flange when seated with a rubber gasket eliminates the problem of electrolysis commonly incurred when the use of an iron flange is connected to copper tubing. Additional wing style "T" handle included with mounting nuts and bolts.

The Original is Still the Best!
