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.
Based on conductivity probe technology, they are specially designed to meet increasing demand for a reliable, cost effective means of sensing water level in boiler and various other applications.
Probes can be mounted directly to the pressure vessel or column.
HP probes feature brazed welded stainless steel electrode with zirconia insulator for high pressure, high temperature applications.
LP probes feature threaded stainless steel electrode with PTFE insulator for lower pressure and temperature applications.
Custom fittings available with probe adapter.
PED 97/23/EC conformance available.
3. Yarway TSL/TSM Liquid Level Gauges
These level gauges are suitable for use in steam service for boiler drum, feedwater heater and other vessel level indication applications. Series TSL and TSM are especially suited to IP and LP combined cycle HRSGs.
Suitable for indoor or outdoor installation.
For use with low maintenance stuffing box gauge valves (nipple connected models).
Through bolt design allows easy servicing.
Cover enclosed glass resists breakage.
Thermally induced linear expansion absorbed within the stuffing box on nipple connected models or by the expansion loop on flange connected models.
Live loaded cover bolting to withstand cyclic service.
Mica shield protection to prevent gauge glass erosion.
Tempered borosilicate glass for high strength and thermal shock resistance.
Steel Valves in 16 Models for Pressures up to 3000 PSI (200 Bar).
SG800 Series Lever Operated Forged Steel Water Gauge Valves
For Dependable Steam Service to 1500 PSI at 600°F
Available with ¾” Male Pipe Connection or Standard ANSI Flange
SG800 Series valves offer choices in vessel and gauge connections, ball check locations, and union availability. Refer to the Model Selection Guide for individual model features to meet your specific installation requirements.
All SG800 Series valves are of outside screw and yolk design.
