steam boilers and waste- heat boilers. Thanks to the pneumatic actuation, the valves are suitable for supervision-free or controlled supervision service in installations with automatically controlled boiler blowdown process.CONSTRUCTION:
The blowdown valve comprises two main functional units:
- valve body,
- pneumatic actuation ODM2, hand lever ODM1.
