What is the difference between the Medium (1018) and Heavy (1019) pattern ferrule cocks?

The heavy pattern (1019) is designed for higher pressure service with shell test pressure of 24 kg/cm²g vs. 20 kg/cm²g for medium pattern. Heavy pattern is available in larger sizes (up to 1") and is recommended for applications with higher system pressures or water hammer conditions.

Can these valves be used for steam service?

The ferrule cocks and ball bib cocks listed here are rated for water service only. For steam applications, refer to Zoloto's bronze water level gauges (Models 1047/1048) which are IBR-compliant and rated for steam at 10.55 kg/cm²g working pressure.

What is the advantage of the Model 1019A with rubber seating over metal-seated ferrule cocks?

The Model 1019A features metal-to-rubber (resilient washer) seating per IS 2692, providing improved sealing at lower operating torques and better tolerance to minor debris in the water. It is ideal for applications requiring frequent operation and bubble-tight shut-off.

Are these valves IBR-approved for boiler applications?

The ferrule cocks and ball bib cocks are not IBR-certified. For IBR-compliant boiler accessories, consider the Zoloto bronze water level gauges (Models 1047/1048) which are manufactured to IBR 282 specifications.

What thread standard do these valves use?

All valves feature screwed male ends conforming to IS 554 / BS 21 / ISO 7. Ferrule cocks have BSPT inlet and BSP outlet; ball bib cocks have BSPT threads. This ensures compatibility with standard Indian and British piping systems.

Overview

Zoloto ferrule cocks and ball bib cocks are robust shut-off valves designed for water service in industrial and commercial installations. These valves are manufactured from high-quality bronze (IS 318 Gr. LTB 2) and forged brass (IS 6912 Gr. FLB), ensuring corrosion resistance and long service life in demanding plant environments.

The ferrule cock range includes medium and heavy-duty patterns featuring metal-to-metal or metal-to-rubber seating for reliable shut-off. The forged brass ball bib cocks offer quarter-turn lever operation with hard chrome-plated brass balls and PTFE seats, providing smooth operation and drip-tight sealing.

All valves feature screwed male ends conforming to IS 554 / BS 21 / ISO 7, ensuring compatibility with standard BSP/BSPT piping systems used across Indian manufacturing facilities.
