Color-Port gauges provide continuous indication of boiler water levels as required by the ASME Boiler and Pressure Code PG-60. A complete Color-Port system includes the gauge, a water column or tie bar, two gauge valves and an illuminator/display. Welbloc L200V gauge valves offered with circulating tie bar is designed to be used with flanged end high pressure gauges for working pressure up to 3000 psi (207 bar) with a stellite disc and an integral stellite seat feature. Internals are completely accessible with the valve connected in the line. This compact design with tie bar reduces installation space, provides greater rigidity and assures minimum temperature differential by allowing more direct flow between drum and gauge.
