Global Exporter-Air volume tanks
Air Volume Tanks for Pneumatic Valve Backup, Oil & Gas & Instrument Air Systems
In critical process industries, compressed air is not just a utility — it is a safety-critical medium.
Air Volume Tanks play a vital role in:
-
Ensuring fail-safe operation of pneumatically actuated valves
-
Maintaining instrument air system stability
-
Supporting continuous operation in Oil & Gas and process plants
At KRR Engineering, we design and manufacture ASME-certified Air Volume Tanks engineered specifically for backup storage, pressure stabilization, and critical process reliability.
Pneumatic Valve Backup Systems (CORE USP) Fail-Safe Air Storage for Pneumatically Operated Valves

Real-World Use Case – Refinery ESD System
A refinery uses pneumatically actuated emergency shutdown valves.
• Compressor stops during power failure
• Air pressure drops rapidly
Without Air Volume Tank:
❌ Valves fail to actuate
With KRR Air Volume Tank:
✔ Stored air ensures valve closure
✔ Safe shutdown achieved
✔ Risk minimized
