Fits precise pneumatic pressure setting on calibration benches where you need an Ashcroft AVC-1000 (vacuum–1000 psi, 0.00025 psi resolution) or AVC-3000 (vacuum–3000 psi, 0.0005 psi resolution)—piston volume controllers with integral balance valves and 1/8 NPT connections.
Key advantages
- AVC-1000 — Vacuum–1000 psi; 0.00025 psi resolution; 31 turns
- AVC-3000 — Vacuum–3000 psi; 0.0005 psi resolution; 61 turns
- Balance valve — Equalizes and protects piston
- Connection — 1/8 NPT female
- Use — Fine pressure dial-in without hunting regulators
Typical applications
- Calibration bench fine adjust.
- Gauge comparator setups.
- Lab pneumatic pressure set.
Selection guide
- 1000 vs 3000 psi
- Bench bracket
- Reference indicator
Common mistakes
- Hydraulic fluid in pneumatic controller.
- Exceeding proof pressure.
- Balance valve left open in test.
