Features
- Pioneering in Polyurethane - Bonded Valves Since 2009, HNA has been the trailblazer in China, being the first manufacturer to design and fabricate polyurethane - bonded valves for American customers. This long - standing commitment to innovation showcases HNA's dedication to meeting international market demands and technological leadership.
- Construction and Materials
- The valve features a high - pressure forged valve body and an investment - cast bottom guide (valve leg/wing), crafted from AISI 8620 (20CrNiMo) steel. Customized materials are available, providing flexibility to adapt to diverse engineering requirements.
- World - Class Heat Treatment
- Subjected to top - notch heat treatment, the valve attains optimal mechanical properties. This includes excellent tensile strength, yield strength, Charpy impact resistance, and elongation. Additionally, its temperature and corrosion resistance performance surpasses API standards, ensuring a significantly extended service life even in harsh operating conditions.
- Advanced Manufacturing Technologies
- The combination of world - class friction - welded technology and precise machining crafts results in high - precision components with a close - tolerance fit. This not only enhances the valve's performance but also its reliability in various applications.
- Versatile Bottom - Guide Valve Body Configurations
- 4 - Wing, 3 - Wing, and custom - designed bottom - guide valve bodies are available, enabling seamless matching with 4 - web, 3 - web, and full - open valve seats. When pumping abrasive mud liquid, the tapered bottom - guide legs play a crucial role. They increase the flow area and reduce fluid velocity, promoting smoother flow. This, in turn, reduces abrasion and extends the valve's service life. The design with tapered bottom - guide legs is especially well - suited for high - pumping - speed operations.
- Sealing Performance of the Bottom Guide
- The precisely tapered and balanced design of the bottom guide ensures uniform loading characteristics, which is essential for superior sealing performance. This design feature effectively prevents leaks and maintains the integrity of the fluid system.
- Two - Piece Welded Design
- The two - piece welded design offers several advantages. It provides enhanced structural stability while also allowing for more efficient manufacturing processes and potential customization options.
- Benefits of Bonded Valve Type
- Enhanced Structural Strength: The bonded valve type exhibits very high tensile strength, significantly increasing the structural integrity and thereby extending the operation life.
- Improved Shock Absorption: It effectively minimizes shock during valve closure, reducing mechanical stress on the valve components and enhancing their durability.
- Superior Sealing Capabilities: By reducing the likelihood of fluid penetration between the polyurethane insert and the valve body, it effectively prevents sealing failures and ensures reliable operation.
- High - Performance Polyurethane
- Imported from the USA, the high - performance polyurethane offers exceptional properties:
- High Extrusion/Abrasion Resistance: Demonstrates extremely perfect resistance, ensuring long - lasting performance in abrasive environments.
- High Chemical/Corrosion Resistance: Shows outstanding resistance to chemical corrosion, making it suitable for a wide range of applications involving corrosive substances.
- High Pressure Resistance: Can withstand a maximum pressure of 7,500 Psi, ensuring reliable operation under high - pressure conditions.
- Temperature - Rated Polyurethane Inserts
- Two temperature - rated polyurethane valve insert options are available: a regular - temperature 220°F (105°C) (yellow) and a high - temperature 300°F (150°C) (white) insert. This allows users to select the most appropriate insert based on the specific operating temperature requirements of their applications.
- Insert Design for Optimal Sealing
- The precisely tapered design of the insert, carefully matched to the seat, provides evenly distributed loading characteristics. This ensures optimal sealing performance. Additionally, double - angle options such as 55°, 45°, or other specified taper designs are available to accommodate different valve types, pump types, and application 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 offers users greater flexibility in system integration.
- Shelf Life
- Under proper storage conditions, the valve has a perfect shelf life of less than 36 months. This ensures that the product remains in excellent condition until it is ready for use, minimizing the risk of degradation over time.
- Extraordinary Long Service Life
- The valve offers an extremely long service life that exceeds API standards. This is a testament to its high - quality construction and superior performance, making it a reliable choice for demanding applications.
- Polyurethane Material Choices
- Customers can choose between domestic high - quality polyurethane and USA high - performance polyurethane. This allows for customization based on performance requirements, cost - effectiveness, and specific application needs.
- Interchangeability
- The valve is fully interchangeable with major valve types such as Roughneck and SWND Bonded Valve. It is available in API 3# through API 9# sizes, as well as Non - API Modified Type & Sizes. This interchangeability simplifies maintenance and replacement processes, reducing downtime and associated costs.
- Customized Rubber Option
- Customized bonded NBR/HNBR rubber is available as an option. This provides an additional level of flexibility to meet the specific requirements of different applications, allowing for tailored solutions.
