Zeron Fastners
Industrial Valves & FastenersCast Steel Gate Valves
Cast Steel Gate Valves conforming to API 600 and BS 1414 are heavy-duty industrial valves designed for on/off isolation of high-volume fluids, steam, and gases in industrial processing pipelines. Employing a cast flexible wedge that compensates for thermal pipe stress and slight body seat deformation under fluctuating temperature cycles, cast steel gate valves deliver dependable bidirectional sealing with minimum head loss when fully open.
Zeron Fastners produces precision API 600 Cast Steel Gate Valves in sizes from 2" to 48" in ASTM A216 WCB, A352 LCC, and Stainless Steel (CF8/CF8M). Designed with Outside Screw & Yoke (OS&Y), rising stem, renewable threaded or welded body seat rings, and bolted bonnets. Suitable for continuous duty in oil refineries, petrochemical complexes, thermal power generation, and water supply grids.
