Features
1. Construction and Materials
- Valve Body and Bottom Guide: The valve consists of a high - pressure forged valve body and an investment - cast bottom guide (referred to as valve leg/wing). The base material is AISI 8620 (20CrNiMo), a steel grade renowned for its mechanical properties. However, customized materials can be provided, enabling adaptation to specific engineering requirements. This flexibility in material selection allows for tailoring the valve's performance to different operating conditions, whether it's resistance to high pressures, corrosion, or other environmental factors.
- Heat Treatment: World - class heat treatment is applied to the valve components. This treatment ensures optimal mechanical properties such as high tensile strength, enabling the valve to withstand substantial forces; good yield strength for predictable deformation under load; excellent Charpy impact resistance to endure sudden impacts; and sufficient elongation for flexibility. Additionally, the heat treatment endows the valve with temperature and corrosion resistance performance that exceeds API standards. This not only extends the valve's service life but also makes it suitable for use in the harshest drilling environments, where high temperatures, corrosive substances, and mechanical stress are common.
- Precision Machining: Precise machining crafts are utilized to manufacture high - precision components. This results in a close - tolerance fit between parts, which is crucial for the valve's performance. A tight fit reduces leakage, enhances the valve's overall efficiency, and minimizes wear and tear, ensuring smooth operation over an extended period.
2. Design for Abrasive Environments
- Bottom - Guide Valve Body Configurations: The availability of 4 - wing, 3 - wing, and custom - designed bottom - guide valve bodies provides versatility. These can be matched with 4 - web, 3 - web, and full - open valve seats, allowing for optimal configuration based on the specific requirements of the pumping system. When pumping abrasive mud liquid, the tapered bottom - guide legs play a vital role. They increase the flow area and reduce the fluid velocity, creating a smoother flow. This, in turn, reduces abrasion on the valve components and extends the valve's service life. The design with tapered bottom - guide legs is particularly well - suited for high - pumping - speed applications, as it can handle the increased flow rate without excessive wear.
- Bottom - Guide Sealing Design: The precisely tapered and balanced design of the bottom guide ensures uniform loading characteristics. This is essential for achieving better sealing performance. When the valve is closed, the uniform loading helps prevent leaks, maintaining the integrity of the fluid system and ensuring efficient operation.
3. Unique Assembled Rotary Valve Body Design
- Automatic Alignment and Stabilization: The assembled rotary valve body type features a unique design with small rolling steel balls evenly spread inside the valve body. This design enables an automatic valve alignment adjusting function. As the valve operates, the rolling balls help the valve self - align, providing an automatic valve - stabilizing feature. This not only improves the valve's sealing performance but also reduces stress on the valve components, potentially extending the valve's lifespan.
4. Cost - Effective Replaceable Insert
- Polyurethane Insert: A replaceable polyurethane valve insert is used, which offers significant cost - savings. Instead of replacing the entire valve when the insert wears out, only the insert needs to be changed. Polyurethane inserts are generally more cost - effective to produce and replace compared to the entire valve assembly. This reduces operational costs, making the valve a more economical choice for long - term use.
5. High - Performance Polyurethane
- Imported from the USA: The high - performance polyurethane imported from the USA exhibits outstanding properties. It has extremely perfect high extrusion/abrasion resistance, which is crucial for withstanding 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. Additionally, it can resist high pressures, with a maximum rating of 7,500 Psi, ensuring reliable performance under the high - pressure conditions typically encountered in drilling operations.
- Temperature - Rated Options: 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.
6. 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.
7. 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.
8. 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.
9. Extended Service Life
- Exceeding Standards: The valve offers a long service life that exceeds API standards. This is a testament to its high - quality construction, from the choice of materials to the manufacturing processes. The extended service life reduces the frequency of valve replacements, which in turn reduces maintenance costs and downtime.
10. 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.
11. Interchangeability
- Compatibility with Major Valve Types: The valve is fully interchangeable with major valve types such as the BOMCO Rotary 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.
12. 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.
