ZOLOTO Cast Steel Globe Steam Stop Valve ( Flanged)
Zoloto 1071 Cast Steel Globe Steam Stop Valve (Flanged)
The Zoloto 1071 Cast Steel Globe Steam Stop Valve is a high-performance, IBR-certified straight-pattern industrial valve built for rigorous high-pressure and high-temperature service. Designed with a bolted bonnet, outside screw and yoke (OS&Y) structure, and rising stem, it provides positive isolation and throttling control for steam, water, oil, and thermic fluid applications.
Key Product Features
- High-Pressure Rating: Engineered to meet DIN 2545 PN 40 flanged connection standards for demanding industrial environments.
- Thermic Fluid Compatible: Built to perform reliably with thermic fluids, high-temperature water, steam, and oil media up to 425°C → 425 degrees Celsius.
- Robust SS 410 Trim: Renewable 13% Chromium Stainless Steel working parts ensure extended operational service life under high erosion.
- Streamlined Flow Path: Contoured internal body design reduces media turbulence and minimizes systemic pressure drops.
- Under-Pressure Repacking: Backseat bush mechanism permits safe gland packing repacking while under system pressure.
