The Ashcroft^® AVC-1000 and 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 gauges, creating a reliable standard for calibration and test purposes.

Features:

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