This package includes a full port ductile iron Watson McDaniel HD main regulating valve with NPT connections paired with a PP-Y pressure pilot and PTUBW-30-8 temperature pilot. The assembly will control a downstream temperature between 160°F-220°F while also controlling a downstream pressure between 3-25 PSI (yellow spring). The temperature pilot includes an 8-foot capillary and copper sensing bulb with brass isolation well. Within boiler feed systems, a combination pressure AND temperature control valve is typically used on an atmospheric feed tanks that utilize a low-pressure steam sparge tube to control the water temperature. The temperature pilot is the primary pilot, it maintains the tank temperature at the desired setpoint. The pressure pilot prevents the low-pressure sparge tube from exceeding its designed operating pressure.
