Better vacuum control for better forming consistency.
How the V-1000 works
The valve is set by a pneumatic pilot which positions the two pistons to expose the correct slot height to produce proper vacuum. When box vacuum levels drop, the pistons automatically move upward, uncovering more vacuum slot area to increase vacuum supply. During vacuum surges, the pistons move downward, covering vacuum slots and exposing air slots to reduce box vacuum levels.
Features/Benefits
- Automatically maintains set vacuum level - "Set-and-forget" operational simplicity - while providing faster, more accurate response to fluctuations in stock and vacuum supply than is possible with manual controls
- High precision - setpoints are maintained to + .5" H2O (12 mm HC) for more consistent drainage and formation
- Low and high-vacuum capability - allows use of graduated vacuum and high-vacuum, high-efficiency dewatering technologies
- Standard pneumatic or optional electronic controls - easily integrated into existing vacuum controls - and mill-wide DCS systems
- Simplicity - a single, compact V-1000 valve provides the same level of vacuum control as a multiple butterfly valve system
- Heavy-duty construction - developed specifically for paper mill environments to minimize plugging and maintenance
- Valve is remotely controlled - operators don't have to climb on machine to change valve settings
- Compatible with standard vacuum headers - valve can be easily retrofitted onto existing vacuum supply systems
