Power Station Globe Valve

The power station globe valve is built for the high pressures and temperatures of boiler feed, main steam and drain lines in thermal power plants. A disc seating onto a hardfaced horizontal seat gives the fine throttling control needed to regulate steam flow, while chromium-molybdenum alloy steel retains strength at elevated temperatures. A pressure-seal or bolted bonnet contains high-energy steam safely, and Stellite-faced trim resists erosion from wet and superheated steam. The globe pattern accepts a higher pressure drop than a gate valve in return for the precise regulation that power-cycle control demands.
