PATENT PENDING
Designed for residential and commercial use to isolate, test andmaintain tankless andon-demandhot water heaters. The
approved heavy duty forged brass body allows for a full flow throughout the valve and drain & fill connection. Additionally,
it meets all requirements set forth in NSF 61-9 for potable water. Both balls are hard chrome plated solid
brass and are sealed with reinforced Teflon® seats. These approved Webstone Isolator® EXPTM valves are
actuated by blowout proof stems with Teflon® seals that feature adjustable packing glands. A vinyl coated
304 stainless steel handle and an epoxy protected aluminum handle allow for outdoor use. This valve set comes
with a hot and cold valve which is depicted by the colored insulator rings on the union connection. The hot water
valve features an outlet for a pressure relief valve that will keep the water heater and system protected at all times.
Packaged pressure relief valves can be included in the set by adding the appropriate suffix to the item number.
