Zy-Tech DSI API 600 Gate Valve FIG G37XUF 8 Inch Class 150 with BG107 Bevel Gear Operator

The Zy-Tech DSI API 600 Gate Valve FIG G37XUF is a robust cast steel gate valve designed for reliable shut-off in industrial pipelines, particularly in oil, gas, water, and chemical processing applications. This 8-inch Class 150 valve features a flexible wedge disc for tight sealing under varying pressures and temperatures, with outside screw and yoke (OS&Y) design for easy maintenance. Constructed with WCB carbon steel body, CR13 stainless steel disc and stem, and hard-faced (HF) seats (API Trim No. 8), it offers excellent corrosion resistance and durability in harsh environments. The included BG107 bevel gear operator provides high torque (up to 1000 ft-lbs) with a 2.92:1 ratio, enabling manual operation of large valves with minimal effort. Benefits include low pressure drop when fully open, bidirectional sealing, and compliance with ASME B16.34 and API 600 standards for safety and performance. Drawbacks may include higher weight compared to lighter ball valves and the need for more space due to the rising stem. Compared to similar products from brands like Velan or Crane, it offers cost-effective reliability with standard flanged connections. This used unit shows rust and wear, suitable for refurbishment in demanding services up to 285 PSI at 100°F.
