Features
The Blow-down valves are specially design for blowing down steam boilers with compressed air. When opened for a short period by pneumatic actuator or manually operated with a lever, they form an eddy of water that entrains sludge from the boiler and. Corrosion is effectively prevented.
The flow always approaches a blow-down valve in closing direction. The closing force
Of the springs is supported by the medium pressure.
