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.
