Bonney Forge 6x4 Inch Class 150 Gate Valve Fig. L-1-RE

The Bonney Forge Fig. L-1-RE is a cast steel gate valve designed for reliable on/off flow control in industrial piping systems. Featuring a reduced bore configuration with 6-inch flanged connections and a 4-inch port, this valve is suitable for applications where full bore is not required, offering cost savings and reduced weight compared to full-bore equivalents. Constructed from ASTM A216 WCB carbon steel body with CR13 trim, it provides good corrosion resistance and durability in moderate temperature and pressure environments. Key features include a bolted bonnet, non-rising stem, and hard-faced seats for enhanced sealing and longevity. It is commonly used in oil and gas, petrochemical, water treatment, and power generation industries for isolating flow in pipelines handling liquids, gases, or slurries. Advantages include low pressure drop when fully open, bidirectional sealing, and ease of maintenance. Drawbacks may include slower operation compared to ball valves and unsuitability for throttling due to potential seat damage. Compared to similar products from competitors like Velan or Crane, Bonney Forge valves are noted for their robust forging heritage, though this cast model emphasizes affordability. Overall, it offers dependable performance in Class 150 systems up to 285 PSI at 100°F.
