Features
- High - Pressure Forged One - Piece Integral Valve Body
- Constructed with a central guide stem, the one - piece integral valve body is forged from AISI 8620 (20CrNiMo) steel. Customized materials are also available upon request to meet diverse engineering demands.
- Exceptional Heat Treatment
- Undergoes world - class heat treatment, ensuring optimal mechanical properties such as high tensile strength, yield strength, excellent Charpy impact resistance, and good elongation. Additionally, its temperature and corrosion resistance performance far exceeds API standards, enabling an extended service life even in the most challenging environments.
- Precision Machining
- World - top - class precise machining crafts are utilized to produce high - precision components with a close - tolerance fit. This results in smooth operation, reduced wear, and enhanced overall performance of the valve.
- Design for Harsh Environments
- Based on an extreme - pressure well - service valve design, the one - piece forged valve body can meet the requirements of the most hostile drilling environments around the world. The tough integral structure with a central guide stem significantly increases the structural strength of the valve body, featuring very high tensile strength for a longer operation life. It also allows for a much larger flow area, effectively reducing abrasion. This design offers superior strength, longer run - times, and cost - savings.
- Central Stem Guide Design Advantages
- The central - stem - guide - designed valve body can be paired with 4 - web, 3 - web, and 2 - web valve seats. The hardened surface of the central stem guide provides high anti - abrasion performance, extending its service life. It ensures precisely balanced guiding and the proper landing of the valve on the seat, resulting in better sealing performance and shock absorption when the valve closes. Moreover, it has a much larger flow area than bottom - guided valves, is lighter in weight, and is more suitable for high - speed, large - flow - rate pumping applications.
- Plate Type/Locknut Design Benefits
- The plate type/locknut design enables precise control of insert loading through a removable flat - ground insert retaining plate/locknut and split retainers. This design allows for easier and quicker insert replacement in the field, minimizing downtime.
- Cost - Effective Replaceable Insert
- A replaceable polyurethane valve insert is used, which effectively reduces operation costs. When the insert is worn out, only it needs to be replaced instead of the entire valve.
- High - Performance Polyurethane
- Imported from the USA, the high - performance polyurethane has the following outstanding features:
- High Extrusion/Abrasion Resistance: Extremely perfect, ensuring long - lasting performance in abrasive environments.
- High Chemical/Corrosion Resistance: Extremely perfect, making it suitable for use in various 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 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. This allows users to choose the most suitable insert based on the operating temperature of their applications.
- 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 the needs of 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 used 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. This ensures that the product remains in good condition until it is put into use.
- Long Service Life
- It offers an extremely long service life that far exceeds API standards, demonstrating its high - quality construction and reliable performance.
- Polyurethane Material Options
- Customers can choose between domestic high - quality polyurethane and USA high - performance polyurethane, depending on their performance requirements and cost - effectiveness considerations.
- Interchangeability
- It is fully interchangeable with major valve types such as FK - 1 Valve, Silver Top Valve, Standard Plate Type Valve, and GD Locknut Valve. Available in API 3# through API 9# sizes, as well as Non - API Modified Type & Sizes, it simplifies maintenance and replacement processes.
- Customized Rubber Option
- Customized replaceable NBR/HNBR rubber is available as an option, providing more flexibility to meet specific application requirements.
- Customized Valve Body Option
- Customized 4 - Wing/3 - Wing Bottom Guide Plate/Locknut Valve Bodies are available, catering to different design and application needs.
