Zoloto Ball Valves - Bronze, Forged Brass & Stainless Steel | Screwed & Flanged

Overview

Zoloto ball valves are designed for reliable shut-off service across a wide range of industrial applications. Available in bronze, forged brass, and stainless steel (SS 304/CF8 and SS 316/CF8M) constructions, these valves offer quarter-turn operation with lever handles for quick and easy flow control.

The product range includes two-piece and three-piece designs with screwed (BSP/NPT) or flanged (ASME B16.5 Class-150) end connections. All variants feature PTFE seats and gland packing for leak-tight sealing and compatibility with water, oil, air, steam, and gases. Maximum working temperatures up to 220°C make these valves suitable for process lines in manufacturing plants, utilities, and HVAC systems.

Zoloto, established in 1966, is a well-known Indian valve manufacturer with ISO certification. Their ball valves conform to standards including IS 554, BS 21, ISO 7, and BS EN ISO 17292.
