API 6A 4-1/16 15000psi Fls-R Ball Screw Operation Gate ...

Ball screw gate valves are designed for large caliber, high pressure manual valves. The valve combines the tail balance lever and the unique ball ball principle to make its operation light, low torque, easy to operate. Its diameters range from 3 1/16 "to 9" and its pressures range from 10,000 psi to 20,000 psi.

Product features:

1. Two-way downstream sealing structure, which improves the service life;

2. Fixed metal seal (between gate and seat and seat and body);

3. Simple and reliable gate and seat design can reduce field service;

4. Sealing ring between seat and body helps seal at low pressure. They also prevent granular contaminants from entering the body chamber and sealing area;

5. Stem seal design covers all pressure classes, temperature ranges, and all fluid conditions encountered in wellhead and manifold environments;

6. Metal seal between bonnet and valve body, up to psi working pressure;

7. Reverse stem seal structure allows valve to replace stem seal under pressure drive;

8. To ensure safety, grease injection device can be placed on the stem after inverted seal. The device can be placed on the bonnet to eliminate body leakage.

9. Ball screw can effectively improve the switching efficiency and reduce the switching torque, which is more conducive to opening and closing the valve easily and quickly.

Key Aspects of the API 6A Standards

The API 6A standards are essential for ensuring the reliability and safety of equipment used in oil and gas drilling and production operations. Compliance with these standards ensures that products like the ball screw gate valves are able to withstand the rigorous demands of high-pressure environments. The 4-1/16 15000psi designation refers to the nominal diameter and working pressure, indicating the valve's compatibility with extreme conditions and its robustness.

Why Choose a Ball Screw Gate Valve?

Ball screw gate valves, with their unique design, offer several advantages over traditional gate valves. The integration of a ball screw mechanism reduces the effort required to operate the valve, making it more efficient and easier to handle. This feature is particularly useful in applications where frequent operation is necessary, or where installation areas are challenging.

Applications Across Various Industries

These valves are indispensable in industries such as:

• Oil and Gas Production: Managing flow rates and ensuring safety in high-pressure environments.
• Chemical Processing: Handling corrosive fluids with their robust sealing mechanisms.
• Power Generation: Controlling steam and other high-pressure fluids efficiently.

Nominal Diameter Details

The nominal diameters for these valves range from 2-1/16 to 7-1/16 inches, providing flexibility for various industrial applications. The exact diameters include:

2-1/16, 2-9/16, 3-1/16(3-1/8), 4-1/16, 5-1/8, 7-1/16

Working Pressure Specifications

The valves can withstand pressures ranging from 10,000 psi to over 20,000 psi, making them suitable for challenging environments where high pressure is a constant factor.

Material and Performance Levels

These valves conform to various specification levels (PSL1 to PSL4) and performance levels (PR1, PR2). The material levels include grades like AA, BB, CC, DD, EE, FF, and HH, ensuring compatibility with a range of working mediums and environmental conditions.

Temperature Levels and Working Mediums

The temperature levels span from K to V, ensuring the valves function correctly in a variety of temperature conditions. They can handle different working mediums such as oil, natural gas, mud, and gas containing H2S or CO2.
