Clark Reliance Bronze Water Gage Valve Set is designed and manufactured for demanding applications. Designated as high-grade valves, all models feature valve bodies & packing nuts of ASME Code Bronze. Additional design features include an 18-position gage lever, integral seats & choice of screwed or flanged connections. Valve control is speeded by quadruple stem threads that allow full open/closed with only one-quarter turn.
Chains & handles that indicate open/closed positions are provide, as required by the ASME BOILER CODE. Lower valves employ a 3/8" pipe tap for blowdown. A complete valve set included upper & lower valve, pyrex tubular glass & guard rods (if mounting centers are specified) & two 5ft. chain lengths. Valve model numbers are stamped on the top of upper valve.
NOTE: Power Plus does not recommend tubular glass for use above 250 WSP
