• Mechanical rotation is directly proportional to volume change due to piston travel
• The integral balance valve equalizes pressure and acts as a pressure-relief valve
• Do not require a compressed air source

The Ashcroft® AVC-3000 pressure volume controllers provide a means to precisely set pressures within a closed pneumatic system. Providing quick-and-easy operation, models are paired with test instruments, creating a reliable standard for calibration and test purposes.
