• Emergency Stop Valve: Automatically switches from regulated to line pressure during stops or power failures.
• Ideal for Large Rolls of Thin Material: Eliminates difficulties in matching torque, tension, and stop requirements.
• Automatic or Manual Version: Offers automated system or manual control of cylinders on multiple range brakes.
• Maximum Application Compatibility: Suitable for both load cell or dancer controlled systems.
• Analog Readout Gauge: Provides easy and convenient pressure monitoring.
• Complete Pneumatic System: Includes MAF-3 air filter, MPC-4 I/P converter, pressure gauge, valves or switches, and quick disconnect terminals.

The Montalvo P-3000-HD Automatic Range Expander allows for a wide range of roll sizes and tensions to operate effectively on various unwind applications. It works in conjunction with a Montalvo multi-range brake and tension controllers like the X-3400-HD-U, D-3400-HD, or DTI-3400-HD to maintain precise tension control. The system facilitates controlled starts and stops, reduces tension-related web breaks, minimizes downtime, and maximizes production, especially effective during rapid deceleration of dancer controlled sheeters.
