Audco IBR Energy Miser Ball Valves
Audco IBR Energy Miser Ball Valves (manufactured under L&T Valves / Audco) are specialized, high-performance 3-piece ball valves engineered specifically for steam applications, boiler installations, and thermal energy recovery systems. Approved under the Indian Boiler Regulations (IBR), these valves provide tight shut-off and minimize energy loss caused by steam leakage across process piping.

Material Options
- Body & End Pieces: ASTM A216 WCB (Carbon Steel), ASTM A105 (Forged CS), ASTM A351 CF8M (SS 316)
- Ball & Stem: Stainless Steel AISI 316 / ASTM A479 TP316 mirror-finished solid ball
- Seat Ring Materials: Virgin PTFE, Carbon-Filled PTFE, or Glass-Filled PTFE (engineered for high steam pressures)
- Gland Packing: Flexible graphite / PTFE for high-temperature stem sealing
Key Features & Applications
- Energy Savings: Built with specialized seat geometries to ensure zero-leakage shut-off, reducing steam waste and operational energy costs.
- Swing-Out Design: The 3-piece construction allows the body to swing out for inline maintenance and seat replacement without dismantling line pipework.
- Safety Features: Integrated blow-out proof stem, antistatic device, and high-integrity stem sealing prevent steam fugitive emissions.
- Common Applications: IBR steam piping networks, boiler feed lines, condensate recovery, steam headers, sterilization equipment, and process heating systems in textile, paper, and chemical plants.
