Spirax Sarco ABV21i/ABV40i Pneumatic Boiler Blowdown Ball Valves
Pneumatic boiler bottom blowdown ball valves with PN40 and Class 300 flange connections.

Spirax Sarco fixed discharge temperature steam traps use the thermostatic liquid-expansion principle. An oil-filled element automatically discharges condensate at a preset fixed temperature, with the discharge temperature adjustable on site. These products are primarily used in systems such as steam tracing lines where subcooling and leak prevention must be controlled. Key selection considerations include the pipe connection type, the pressure rating and material of the valve body, and the precise operating temperature range required by the process.
