Features
- A rugged, reliable and accurate 3-way vacuum control valve that improves forming table operation, providing precise control, atmospheric vacuum break and increased flexibility.
- The Accu-Vac design minimizes maintenance cost associated with typical vacuum control valves and provides for simple operation.
- Valve controls allows for integration with existing mill-wide control systems or stand-alone closed-loop systems.
- Accu-Vac's unique actuator, along with three-step algorithmic range control, provides the user with a responsive, positive and powerful vacuum control valve that eliminates sticking.
