The PCVM (Pressure Control Valve Main) is an automated pressure control station designed for pressure regulation of the main steam supply line of the corrugator.

The main features of this station include:

• Automatic soft start-up of steam supply
• Automatic closing of steam supply
• Stand-by steam supply at low pressure over night stops
• Pressure regulation of the steam supply to the corrugator (this would make possible, for example, to keep the whole steam supply at low pressure for stand-by conditions).
