Blowdown valves for boilers

November 2014 Valves, Actuators & Pump Control

Blowdown valves are a popular category of pipe valve, used in a wide variety of applications, in particular in the sugar industry. They are used to control a continuous flow of steam/fluid under high differential pressure. The outstanding features of this type of valve are that it can maintain fluid tightness and is easily operated without the help of any wedging action.

Mitech’s automated Globe Blowdown valves are a recognised standard in the sugar industry as they eliminate the need for the operator to manually blowdown the boiler, typically on mud drum blowdown applications. Valves are typically built with a stellite plug and seat, an oversized actuator and extended mounting bars, and can be either on/off or used in modulating control mode.

Mud drum blowdown valves are used on boilers to clean the drum of soluble and insoluble solids that collect at the bottom during normal operation. Applications vary from boiler to boiler as each one is designed for specific pressures and temperatures.
