Valves

Ball, check, gate, globe, butterfly and balancing valves, pressure reducing valves, backflow preventers and vacuum breakers for potable water, hydronic heating, steam and gas.

Body material sets the application. Brass and bronze cover most service; anything on a potable line installed after 2014 must be lead-free under the Safe Drinking Water Act, which is why lead-free forged brass and no-lead brass are called out separately in the listings rather than lumped in with plain brass.

Connections are stocked in FIP, sweat, press and PEX, in 1/2" through 2" with larger sizes available. Pressure ratings run 200 to 600 WOG — that figure is for water, oil and gas at ambient temperature, and the steam rating (WSP) is always lower, so a valve marked 150 WSP / 600 WOG is limited by the 150 on a steam line.

Brands include Jomar, Legend Valve, Milwaukee Valve, Apollo-Conbraco and Resideo.
