1. **Standards**: These valves adhere to standards such as API 600, API 6D, API 603, API 602, ASME B16.34, and others. For instance, API 603 valves are often made of stainless steel with a body-sealing design, while API 602 covers forged steel valves with various pressure ratings .
2. **Design**: They can be a wedge-type elastic gate structure with a self-sealing mechanism, suitable for high-temperature and corrosive environments. The gate valve's design minimizes pressure drop when fully open and provides a straight path for the fluid flow, which is beneficial for applications like pipeline cleaning .
3. **Materials**: Constructed from a variety of materials including carbon steel, stainless steel (such as CF8, CF3, CF8M, CF3M), and duplex steel, allowing them to be suitable for a wide range of applications and media .
4. **Sizes**: Available in a range of sizes from small diameters up to large diameters suitable for medium and large pipe lines .
5. **Pressure Ratings**: They come in various pressure ratings such as 150Lb, 300Lb, 600Lb, 900Lb, 1500Lb, and 2500Lb, which cater to different pipeline pressures .
6. **Sealing**: The sealing surfaces of the gate and valve seats may be made of Stellite (a cobalt-based hardfacing material) or other alloys for high resistance to wear, corrosion, and temperature .
7. **Actuators**: Gate valves can be actuated manually, by gear, electric, pneumatic, or hydraulic means, allowing for remote operation where necessary .
8. **Applications**: They are used in industries such as oil and gas, chemical, power generation, water treatment, and more, where they are required to control the flow of various fluids .
9. **Connection Types**: Offered with different types of connections like flanged, butt weld, and others, conforming to standards such as ASME B16.5, ASME B16.47, and ASME B16.25 .
10. **Dimensions**: The dimensions of American standard gate valves follow standards like ASME B16.10 for face-to-face and end-to-end dimensions, ensuring compatibility with other pipeline components .
These valves are known for their durability, reliability, and the ability to provide a tight shut-off, making them a preferred choice in many industrial applications. When selecting a gate valve, it is important to consider the specific requirements of the application, including the type of medium, pressure, temperature, and the necessary standards compliance.
