Details
The Piston Desuperheater is used for steam temperature control systems in industry and power engineering. It offers important advantages, including perfect atomization of water and high rangeability.
Piston Desuperheaters Type ST-1
Piston Desuperheaters Type ST-1
- Possible customizing of the device design to adjust flow rates to customers’ demands.
- Removing of device vibrations owing to the support on a pipeline connecting stud.
- Resistance to loss of tightness due to application of a spiral and spring.
- Washer made of metal and graphite and installed on the connecting stud.
- Wide range of flange connections.
- Selection of materials according to customers’ demands.
- Easy replacement of the seat and other internal components of the desuperheater.
- Possible application of a uniformed type of pneumatic actuators with stroke range up to 100 mm.
- Possible use of other actuators upon customers’ requirements, including pneumatic, electric or hydraulic driving units.
