Features
- Industry - First Innovation Since 2009, HNA has been the pioneer in China to design and fabricate polyurethane - bonded valves for American clients. This achievement not only showcases HNA's technological prowess but also its commitment to meeting international market demands.
- High - Pressure Forged One - Piece Integral Valve Body Constructed with a bottom guide (valve leg/wing), the valve body is made of AISI 8620 (20CrNiMo) steel. This material choice ensures high - strength performance under extreme conditions. Additionally, customized materials are available upon request, providing flexibility to meet diverse application requirements.
- World - Class Heat Treatment Subjected to top - tier heat treatment processes, the valve body attains optimal mechanical properties. These include outstanding tensile strength, yield strength, Charpy impact resistance, and elongation. Moreover, its temperature and corrosion resistance performance far exceeds API standards, guaranteeing an extended service life even in the harshest environments.
- Precision Machining Crafts Employing world - leading precise machining techniques, HNA produces high - precision components. The close - tolerance fit achieved through these crafts ensures smooth operation, reduced wear, and enhanced overall performance of the valve.
- Design for Harsh Environments The one - piece forged valve body is engineered based on extreme - pressure well service valve designs, making it suitable for the most challenging drilling environments globally. The tough integral structure, combined with a tapered leg guide, significantly enhances the structural strength of the valve body. This results in very high tensile strength, prolonging the operation life. Meanwhile, it allows for a larger flow area, effectively reducing abrasion and fluid velocity. This design not only offers superior strength and longer run - times but also contributes to cost - effectiveness.
- Versatile Bottom - Guide Valve Body Options Available in 4 - Wing, 3 - Wing, and custom - designed configurations, the bottom - guide valve body can be seamlessly matched with 4 - web, 3 - web, and full - open valve seats. When dealing with abrasive mud liquids, the tapered bottom - guide legs play a crucial role. They increase the flow area and decrease the 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 applications.
- Sealing Performance of the Bottom Guide The precisely tapered and balanced design of the bottom guide is a key factor in ensuring excellent sealing performance. It provides uniform loading characteristics, preventing leakage and maintaining the integrity of the valve system.
- Advantages of Bonded Valve Type
- Enhanced Structural Strength: Boasting very high tensile strength, the bonded valve type significantly increases the structural integrity, leading to a longer operation life.
- Improved Shock Absorption: Minimizes shock during valve closure, reducing mechanical stress and potential damage to the valve components.
- Superior Sealing Capabilities: Reduces the likelihood of fluid penetration between the polyurethane insert and the valve body, effectively preventing sealing failures and ensuring reliable operation.
- USA - Imported High - Performance Polyurethane
- Exceptional Extrusion/Abrasion Resistance: Demonstrates extremely perfect resistance to extrusion and abrasion, ensuring long - lasting performance even in abrasive environments.
- Outstanding Chemical/Corrosion Resistance: Exhibits remarkable resistance to chemical corrosion, making it suitable for use in a wide range of chemical - laden applications.
- High Pressure Resistance: Can withstand a maximum pressure of 7,500 Psi, providing reliable performance under high - pressure conditions.
- Temperature - Rated Polyurethane Valve Inserts Two options are available: a regular - temperature 220°F (105°C) (yellow) polyurethane valve insert and a high - temperature 300°F (150°C) (white) polyurethane valve insert. This allows users to select the most suitable insert based on the operating temperature requirements of their specific applications.
- Insert Design for Optimal Sealing The precisely tapered design of the insert is carefully crafted to match the seat perfectly. This design provides evenly distributed loading characteristics, ensuring optimal sealing performance. Additionally, double - angle options of 55°, 45°, or other specified taper designs are available to accommodate different valve types, pump types, and application scenarios.
- Compatibility with Valve Seats 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 feature provides users with more 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 optimal condition until it is ready for use, minimizing the risk of degradation over time.
- Extraordinary Long Service Life The HNA Bottom Guide Valve Body, featuring a one - piece forged construction with bonded polyurethane, is the ultimate choice for the toughest well - service environments. It offers an extremely long service life of over 600 hours, outperforming many other products in the market.
- Polyurethane Material Choices Customers have the option to choose between domestic high - quality polyurethane and USA high - performance polyurethane. This choice allows for customization based on specific performance requirements and cost - effectiveness considerations.
- Interchangeability Fully interchangeable with major valve types such as Roughneck Bonded Valve and SWND Bonded Valve, the HNA valve is available in API 3# through API 9# sizes, as well as Non - API Modified Type & Sizes. This interchangeability feature simplifies maintenance and replacement processes, reducing downtime and costs.
- Customized Rubber Option Customized bonded NBR/HNBR rubber is available as an option, providing further flexibility to meet specific application requirements. This allows users to tailor the valve to their unique operating conditions.
