Features
- Valve Body and Bottom Guide Structure & Materials
- The valve consists of a high - pressure forged valve body and an investment - cast bottom guide (valve leg/wing). It is made from AISI 8620(20CrNiMo) or AISI 8620H(20CrNiMoH). Custom materials are also available upon request, providing flexibility to meet various engineering demands.
- Heat Treatment and Carburizing Technology
- World - class heat treatment and carburizing technology are implemented. This ensures optimal mechanical properties such as tensile strength, yield strength, Charpy impact strength, elongation, etc., with a surface hardness of 60 - 65 HRC. The temperature and corrosion resistance performance exceeds API standards, significantly extending the valve's service life. This not only makes the valve more durable but also suitable for harsh working environments.
- Friction Welding and Precision Machining
- World - top - class friction - welded technology and precise machining crafts are utilized. High - precision components with a close - tolerance fit are produced, guaranteeing the valve's reliable operation, reducing wear and tear, and enhancing its overall performance.
- Outstanding Performance and Applications
- HNA valves meet the API standard for cementing and fracturing media like sand and man - made resin - coated sand proppants. They demonstrate unparalleled performance under extreme conditions. For example, when pumping high - strength ceramic proppants or sintered bauxite proppants at pressures over 15,000 psi and pump rates exceeding 1,000 SPM, the valves perform exceptionally well. Additionally, multiple elastomers are available for customized applications, enabling the valves to adapt to specific project requirements.
- Bottom Guide Design
- 4 - wing, 3 - wing, and custom - designed bottom - guide valve bodies can be paired with full - open valve seats. When pumping abrasive mud liquid, the tapered bottom - guide legs increase the flow area and reduce fluid velocity, creating a smoother flow. This effectively reduces abrasion and extends the valve's service life. The design with tapered bottom - guide legs is especially suitable for high - speed pumping, ensuring stable and efficient operation.
- The precisely tapered and balanced design of the bottom guide provides uniform loading characteristics, thereby ensuring better sealing performance. This design feature not only prevents leakage but also enhances the valve's overall efficiency.
- Two - Piece Welded Design
- The two - piece welded design is a unique feature of this valve. It offers specific advantages in terms of structure and performance, potentially enhancing the valve's strength and adaptability to different operating conditions.
- Replaceable Snap - On Polyurethane Valve Insert
- The use of a replaceable snap - on polyurethane valve insert significantly reduces operation costs. Instead of replacing the entire valve when the insert wears out, only the insert needs to be changed, making maintenance more cost - effective.
- High - Performance Polyurethane
- The high - performance polyurethane imported from the USA has the following excellent properties:
- Exceptional Extrusion/Abrasion Resistance: It shows extremely perfect high extrusion/abrasion resistance, enabling it to withstand the harsh abrasive forces 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 resist 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 choose the most appropriate insert according to the actual operating temperature of their applications.
- Sealing Design
- The precisely tapered design of the insert, which matches the seat, provides evenly distributed loading characteristics, ensuring better sealing performance. Double - angle designs of 55°, 45°, or other specified tapers are available to meet different valve types, pump types, and applications. This adaptability ensures that the valve can achieve optimal sealing 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 more options in system configuration.
- 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 needed.
- Long Service Life
- The valve offers a long service life that exceeds API standards. This long - lasting performance reflects the high - quality construction and advanced manufacturing processes, reducing the frequency of replacements and maintenance costs.
- Polyurethane Material Options
- Customers can 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 the most suitable choice for their projects.
- Interchangeability
- The valve is fully interchangeable with major valve types such as Service Master Drilling, Service Master II Valve, Cast - N - Place Valve, etc. 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 upgrade, offering convenience to users.
- Customized Replaceable NBR/HNBR Rubber Option
- Customized replaceable NBR/HNBR rubber is available as an option. This allows for further customization to meet specific application requirements, such as enhanced chemical resistance or better sealing performance in certain environments.
