Overview of Bolted Bonnet Gate Valves
Bolted bonnet gate valves are a type of gate valve where the bonnet (the upper part of the valve that houses the stem and actuation mechanism) is attached to the valve body using bolts. This design allows for easy access to the internal components for maintenance and repair. These valves are widely used in applications requiring high pressure and temperature control, such as oil refineries, power plants, and chemical processing facilities.
Comparative Analysis: API 600 vs. ASME B16.34
To better understand the differences between API 600 and ASME B16.34 bolted bonnet gate valves, the following table provides a detailed comparison of their key features, advantages, and disadvantages:
| Feature/Aspect | API 600 | ASME B16.34 |
| Construction | Heavy-duty steel, full-port design | Standard steel, available in various materials |
| Sealing | Enhanced with backseat, lantern ring | Standard sealing, suitable for general applications |
| Maintenance | Easy access, bolted bonnet | Standard maintenance, slightly more frequent |
| Pressure Classes | 150, 300, 600, 900, 1500, 2500 | 150, 300, 600, 900, 1500, 2500 |
| Temperature Range | Up to 850°F (454°C) | Wide range, from cryogenic to high temperatures |
| Cost | Higher due to heavy-duty design | Lower, more cost-effective |
| Installation | Complex due to robust design | Standard, easier integration |
| Weight and Size | Larger and heavier | Standard size and weight |
| Applications | Severe service conditions, high pressure, high temperature | General industrial applications, versatile |
