Features
- Valve Body Structure and Materials
- The valve body is a high - pressure forged one - piece integral structure with a bottom guide (valve leg/wing). It is made from AISI 8620(20CrNiMo) or AISI 8620H(20CrNiMoH). Customized materials are also available upon request.
- Advanced Heat Treatment and Carburizing Technology
- World - class heat treatment and carburizing technology are applied. This ensures optimal mechanical properties including tensile strength, yield strength, Charpy impact strength, elongation, etc., with a surface hardness of 60 - 65 HRC. The temperature and corrosion resistance performance exceed API standards, resulting in an extended service life.
- Precision Machining
- World - top - class precise machining crafts are used to produce high - precision components with a close - tolerance fit.
- Superior Performance in Demanding Applications
- HNA valves meet the API standard for cementing and fracturing media such as sand and man - made resin - coated sand proppants. They offer unparalleled performance under extreme conditions. For instance, 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 custom - fitting specific applications.
- Design Advantages
- The one - piece forged valve body, based on an extreme - pressure well - service valve design, can meet the requirements of the harshest drilling environments globally. The tough integral valve body with a tapered leg guide enhances the structural strength of the valve body due to its very high tensile strength, thus extending the operation life. It also increases the flow area, reduces abrasion, and decreases fluid velocity. This design provides superior strength, longer run - times, and cost - savings.
- The 4 - wing, 3 - wing, and custom - designed bottom - guide valve bodies can be matched 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 reduces abrasion and extends the valve's service life. The design with tapered bottom - guide legs is more suitable for high - speed pumping.
- The precisely tapered and balanced design of the bottom guide ensures uniform loading characteristics, which in turn guarantees better sealing performance.
- Cost - Effective Replaceable Insert
- A replaceable snap - on polyurethane valve insert is used, which reduces operation costs.
- High - Performance Polyurethane
- Imported from the USA, the high - performance polyurethane has the following excellent properties:
- High Extrusion/Abrasion Resistance: Extremely perfect.
- High Chemical/Corrosion Resistance: Extremely perfect.
- High Pressure Resistance: Maximum 15000 Psi.
- Temperature - Rated Polyurethane Inserts
- There are two options for polyurethane valve inserts: a regular - temperature 220°F (105°C) (yellow) insert and a high - temperature 300°F (150°C) (white) insert.
- Insert Design for Sealing
- 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.
- 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.
- Shelf Life
- Under proper storage conditions, the valve has a perfect shelf life of less than 36 months.
- Long Service Life
- The valve offers an extremely long service life that far exceeds API standards.
- Polyurethane Material Options
- Customers can choose between domestic high - quality polyurethane and USA high - performance polyurethane.
- 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.
- Customized Rubber Option
- Customized replaceable NBR/HNBR rubber is available as an option.
