How Does It Work?
Condensate lifts the disc and is discharged. When steam arrives, velocity under the disc increases, pressure drops and the pressure in the control chamber closes the disc.
Applications
- Irons and ironing presses
- Steam tracing lines
- Drying units
- Pressing units
- Steam-jacketed pipes
