Features
- Pioneering Position in the Industry
- Since 2009, HNA has been the trailblazer in China, being the first manufacturer to design and fabricate polyurethane - bonded valves for American customers. This early - mover advantage not only showcases HNA's technical expertise but also its ability to meet the stringent demands of international markets.
- Valve Body and Bottom Guide Composition
- The valve is constructed with a high - pressure forged valve body and an investment - cast bottom guide (referred to as valve leg/wing). The materials used are AISI 8620(20CrNiMo) or AISI 8620H(20CrNiMoH). Additionally, customized materials can be provided, offering flexibility to address diverse engineering requirements.
- Advanced Heat Treatment and Carburizing Techniques
- World - class heat treatment and carburizing technology are employed. This ensures the valve attains optimal mechanical properties including high tensile strength, yield strength, Charpy impact strength, and elongation. With a surface hardness of 60 - 65 HRC, the valve also exhibits temperature and corrosion resistance performance that surpasses API standards. This results in an extended service life, making it suitable for the harshest operating conditions.
- Cutting - Edge Friction Welding and Precision Machining
- Harnessing world - top - class friction - welded technology and precise machining crafts, high - precision components with a close - tolerance fit are produced. This meticulous manufacturing process guarantees the valve's reliable operation, reduces wear and tear, and enhances its overall performance and durability.
- Superior Performance in Demanding Applications
- HNA valves adhere to the API standard for cementing and fracturing media such as sand and man - made resin - coated sand proppants. Under extreme conditions, like pumping high - strength ceramic proppants or sintered bauxite proppants at pressures exceeding 15,000 psi and pump rates above 1,000 SPM, these valves deliver unparalleled performance. Moreover, multiple elastomers are available, enabling customization to fit specific applications precisely.
- Bottom Guide Design for Optimal Flow and Durability
- The valve body comes with 4 - wing, 3 - wing, and custom - designed bottom guides that can be paired with full - open valve seats. When pumping abrasive mud liquid, the tapered bottom - guide legs increase the flow area and decrease the fluid velocity, facilitating a smoother flow. This design not only reduces abrasion but also extends the valve's service life. The tapered bottom - guide legs design is particularly well - suited for high - speed pumping, ensuring efficient and stable operation.
- Precise Bottom Guide Design for Enhanced Sealing
- The precisely tapered and balanced design of the bottom guide ensures uniform loading characteristics. This, in turn, guarantees better sealing performance, preventing leaks and maintaining the integrity of the fluid system.
- Two - Piece Welded Design
- The two - piece welded design is a distinct feature of this valve. It offers unique advantages in terms of structural integrity and adaptability to different operational requirements, potentially enhancing the valve's overall strength and performance.
- Benefits of the Bonded Valve Type
- Increased Structural Strength: The bonded valve type significantly increases the structural strength with its very high tensile strength, thereby extending the valve's operational lifespan. This is crucial for withstanding the harsh conditions in well - service applications.
- Improved Shock Absorption: It effectively improves shock absorption and minimizes the shock when the valve closes. This not only protects the valve components but also reduces the impact on the entire system, ensuring smooth operation.
- Enhanced Sealing Capabilities: By reducing the likelihood of fluids penetrating between the polyurethane insert and the valve body, it enhances the sealing capabilities and prevents sealing failures. This is vital for maintaining the efficiency of the fluid system.
- High - Performance Polyurethane Imported from the USA
- The high - performance polyurethane imported from the USA exhibits outstanding properties:
- Exceptional Extrusion/Abrasion Resistance: It demonstrates extremely perfect high extrusion/abrasion resistance, enabling it to endure the abrasive forces encountered in drilling operations.
- Superior Chemical/Corrosion Resistance: Its high chemical/corrosion resistance is extremely perfect, making it suitable for use in environments with corrosive substances.
- High Pressure Resistance: It can withstand a maximum pressure of 15,000 Psi, ensuring reliable performance under high - pressure conditions.
- Temperature - Rated Polyurethane Insert Options
- There are two temperature - rated polyurethane valve insert options available: a regular - temperature 220°F (105°C) (yellow) insert and a high - temperature 300°F (150°C) (white) insert. This allows users to select the most appropriate insert based on the operating temperature of their specific applications.
- Precise Insert Design for Optimal Sealing
- 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. Double - angle designs of 55°, 45°, or other specified tapers are available to accommodate different valve types, pump types, and applications, optimizing the valve's performance in various scenarios.
- Valve Seat Compatibility
- The valve is compatible with both API 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 enables maximum fluid flow and a longer service life. This compatibility provides users with flexibility in system configuration and enhances the overall performance of the valve system.
- Shelf Life
- Under proper storage conditions, the valve has a perfect shelf life of less than 36 months. This ensures that the valve remains in good condition and ready for use when required, maintaining its quality and performance over time.
- Exceptionally Long Service Life
- The valve offers an extremely long service life that exceeds the API standard. This long - lasting performance is a testament to the high - quality materials, advanced manufacturing techniques, and meticulous design, reducing the need for frequent replacements and lowering maintenance costs.
- Polyurethane Material Options
- Customers have the option to choose between domestic high - quality polyurethane and USA high - performance polyurethane. This provides flexibility in terms of performance requirements and cost - effectiveness, allowing users to make an informed decision based on their project's specific needs.
- Interchangeability
- The valve is fully interchangeable with SPM 2.0 Valve and other major bonded valve types. 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 valve replacement and system upgrades, offering convenience to users and enabling seamless integration into different systems.
- Customized Bonded NBR/HNBR Rubber Option
- Customized bonded NBR/HNBR rubber is available as an option. This allows for further customization to meet specific application requirements, such as enhanced chemical resistance, improved sealing performance, or better adaptability to certain operating conditions.
