ZOLOTO Bronze Auxiliary Steam Stop Valve Straight Pattern (Flanged)

The Zoloto Bronze Globe Steam Stop Valve (Art No. 1042 / Flanged) is a high-performance industrial flow-control valve engineered specifically for high-pressure steam distribution and hot water management. Certified under Indian Boiler Regulations (IBR), this heavy-duty valve offers long-term durability in severe thermal environments.

Key Engineering & Architectural Features

• Straight-Pattern Flow Path: Built with a straight-through body design to maintain efficient fluid dynamics while offering precise throttling and shut-off capability.
• Flanged Connection Ends: Designed with flanged ends conforming strictly to BS 10 Table 'H' for robust pipe connection in high-stress systems.
• Renewable Stainless Steel Trim: Equipped with heat-treated 13% Chromium Stainless Steel (SS 410) internal working parts (body seat ring, disc, and stem) to resist wear, erosion, and thermal distortion.
• Pressure Re-packing Capability: Engineered with an inside screw and rising stem mechanism that allows for online gland re-packing while the system remains under active pressure.
• Lubricated Gland Packing: Utilizes premium lubricated asbestos gland packing (IS 4687) to reduce stem friction and prevent operational leaks.

Technical Specifications & Test Ratings

• Available Sizes: Manufactured in nominal bore sizes from 15 mm (1/2") to 50 mm (2").
• Hydrostatic Shell Test Pressure: 35 kg/cm²g (500 psig).
• Maximum Steam Working Pressure: 17.5 kg/cm²g (250 psig) .
• Maximum Working Temperature: Rated for high-temperature service up to 225°C.
