VAT PL-3 Adaptive Pressure Controller

The VAT PL-3 Adaptive Pressure Controller is a precision pressure regulation unit engineered for vacuum applications requiring dynamic response to changing process conditions. Operating exclusively with VAT Series 61 control butterfly valves, the PL-3 delivers stable, accurate pressure control through integrated learning algorithms that automatically optimize system performance for speed, conductance, and stability.

– Technical Specifications

• Mains Voltage: 100-240 VAC (±10%), 50/60 Hz
• Operating Temperature: 0 – 50 °C
• Sensor Input Signal: 0-10 VDC maximum
• Control Modes: Pressure Mode (PRES) and Position Mode (POS)
