Features
1. Robust Construction
- Material: The valve body is a high - pressure forged one - piece integral structure equipped with a central guide stem. It is made from AISI 8620 (20CrNiMo) steel, known for its excellent mechanical properties. Alternatively, customized materials can be provided to meet specific project requirements. This flexibility in material selection allows for tailoring the valve's performance to different operating conditions.
- Heat Treatment: Subjected to world - class heat treatment, the valve attains top - notch mechanical properties. It exhibits high tensile strength, enabling it to endure the extreme pressures encountered in well - service applications. The yield strength ensures predictable deformation under load, while the high Charpy impact resistance guards against sudden impacts. Good elongation provides some flexibility to the valve body. Moreover, its temperature and corrosion resistance performance surpasses API standards. This not only extends the valve's service life but also makes it suitable for the most hostile drilling environments, where high temperatures, corrosive substances, and mechanical stress are common.
- Machining: World - top - class precise machining crafts are employed to manufacture high - precision components. The resulting close - tolerance fit between components enhances the valve's performance, reduces wear and tear, and ensures smooth and reliable operation over an extended period.
2. Design for Harsh Environments
- Overall Structure: The one - piece forged valve body is designed for extreme - pressure well - service applications. It is engineered to meet the demands of the most challenging drilling environments across the globe. The combination of a tough integral structure and a central guide stem significantly enhances the valve body's structural strength. The high tensile strength of the valve body allows it to operate for a longer time without failure. Additionally, the design provides a much larger flow area, which helps in reducing abrasion caused by high - velocity fluids. This leads to superior strength, longer run - times between maintenance intervals, and cost - savings in the long run.
- Central Stem Guide Design: The valve body with a central stem guide design can be paired with 4 - web, 3 - web, and 2 - web valve seats, offering versatility in system design. The hardened surface of the central stem guide provides excellent anti - abrasion performance. This not only extends the guide's service life but also ensures precise and balanced guiding of the valve onto the seat. As a result, when the valve closes, it achieves better sealing performance, preventing leaks, and effectively absorbs shock, reducing mechanical stress on the valve components. Compared to bottom - guided valves, the central stem guide design offers a larger flow area, making it more suitable for large - flow - rate applications. Its lighter weight is an added advantage, especially for high - speed pumping operations where energy efficiency is crucial.
3. Nut - Type Insert Management
- Design for Easy Insert Replacement: The nut - type design features a removable screwed - on nut retainer plate with hammer lugs. This design allows for precise control of insert loading. In the field, the insert can be replaced more easily and quickly, minimizing downtime. The hammer lugs provide a convenient way to tighten or loosen the nut, facilitating the replacement process even in less - than - ideal working conditions. This is highly beneficial in drilling operations, where any downtime can result in significant costs.
4. Cost - Effective Replaceable Insert
- Polyurethane Insert: A replaceable polyurethane valve insert is used, which is a cost - effective solution. Instead of replacing the entire valve when the insert wears out, only the insert needs to be changed. This reduces operational costs, as polyurethane inserts are generally more affordable to produce and replace compared to the entire valve assembly.
5. High - Performance Polyurethane
- Imported from the USA: The high - performance polyurethane offers outstanding properties. It has extremely high extrusion/abrasion resistance, enabling it to withstand the abrasive forces of drilling fluids. Its high chemical/corrosion resistance makes it suitable for use in environments where the fluids may contain corrosive substances. It can also resist high pressures, with a maximum rating of 7,500 Psi, ensuring reliable performance under the high - pressure conditions often encountered in drilling operations.
6. Temperature - Rated Polyurethane Inserts
- Options for Different Temperatures: Two temperature - rated polyurethane valve inserts are available. The regular - temperature 220°F (105°C) (yellow) insert is suitable for applications where the operating temperature remains within this range. The high - temperature 300°F (150°C) (white) insert is designed for more extreme heat conditions. This allows users to select the most appropriate insert based on the specific temperature requirements of their drilling operations.
7. Insert Design for Sealing
- Precise Tapered Design: The precisely tapered design of the insert, which is carefully matched to the seat, provides evenly distributed loading characteristics. This is essential for ensuring better sealing performance. To accommodate different valve types, pump types, and applications, double - angle designs such as 55°, 45°, or other specified tapers are available. This adaptability ensures that the valve can be optimized for various operating conditions.
8. Valve Seat Compatibility
- Versatile Compatibility: The valve is compatible with both API - standard valve seats and non - API modified valve seats. When paired with the HNA valve seat, the large metal - to - metal bearing area on the valve - seat surface allows for maximum fluid flow. This also contributes to a longer service life, as the increased contact area distributes stress more evenly, reducing wear and tear.
9. Shelf Life
- Long - Lasting Storage: Under proper storage conditions, the valve has a perfect shelf life of less than 36 months. This means that the valve can be stored for up to this period without significant degradation in its performance. Proper storage conditions ensure that the valve remains in a ready - to - use state until it is installed in the drilling operation.
10. Extended Service Life
- Exceeding Standards: The valve offers an extremely long service life that far exceeds API standards. This is a testament to its high - quality construction, from the choice of materials to the manufacturing processes. The long service life reduces the frequency of valve replacements, which in turn reduces maintenance costs and downtime.
11. Polyurethane Material Options
- Customizable Selection: Customers have the option to choose between domestic high - quality polyurethane and USA - imported high - performance polyurethane. This allows for customization based on performance requirements, cost - effectiveness, and specific project needs. For example, domestic polyurethane may be a more cost - effective option for less demanding applications, while the USA - imported high - performance polyurethane may be preferred for extreme conditions.
12. Interchangeability
- Compatibility with Major Valve Types: The valve is fully interchangeable with major valve types such as Supreme Valve, Mud King Valve, and SWU Valve. It is available in API 3# through API 9# sizes, as well as non - API modified types and sizes. This interchangeability simplifies the process of replacing valves in existing systems. It also provides users with more options when choosing components for their drilling operations, as they can select from a range of compatible valve types.
13. Customized Rubber Option
- Tailored Sealing Solution: Customized replaceable NBR/HNBR rubber is available as an option. This provides an additional level of flexibility to meet specific application requirements. NBR/HNBR rubber may offer different properties, such as better resistance to certain chemicals or improved sealing characteristics, depending on the nature of the drilling fluid and the operating conditions.
14. Customized Valve Body Option
- Flexible Valve Body Design: Customized 4 - Wing/3 - Wing Bottom Guide Nut Valve Bodies are available. This allows for further customization of the valve body to meet specific design and performance requirements. For example, the number of wings and the type of bottom guide can be selected based on the flow characteristics and mechanical requirements of the drilling system.
