Features
- Construction Materials and Design
- The valve consists of a high - pressure forged valve body and an investment - cast bottom guide (valve leg/wing), made from AISI 8620 (20CrNiMo) steel. Customized materials are also an option, providing flexibility to meet different engineering requirements.
- Superior Heat Treatment
- Undergoing world - class heat treatment, the valve attains optimal mechanical properties. This includes excellent tensile strength, yield strength, Charpy impact resistance, and elongation. Moreover, its temperature and corrosion resistance performance exceeds API standards, ensuring an extended service life even in harsh conditions.
- Advanced Manufacturing Technologies
- World - class friction - welded technology, combined with precise machining crafts, results in high - precision machined components. This enables a close - tolerance fit, contributing to the valve's reliable and efficient operation.
- Versatile Bottom - Guide Valve Body
- 4 - Wing, 3 - Wing, and custom - designed bottom - guide valve bodies are available, which can be matched with 4 - web, 3 - web, and full - open valve seats. When pumping abrasive mud liquid, the tapered bottom - guide legs increase the flow area and reduce fluid velocity. This creates a smoother flow, reducing abrasion and extending the valve's service life. The tapered bottom - guide legs design is particularly suitable for high - pumping - speed applications.
- Sealing Performance of the Bottom Guide
- The precisely tapered and balanced design of the bottom guide offers uniform loading characteristics, ensuring better sealing performance. This helps prevent leaks and maintain the integrity of the fluid system.
- Two - Piece Welded Design
- The two - piece welded design not only provides structural stability but also allows for easier manufacturing and potential customization.
- Cost - Effective Replaceable Insert
- A replaceable Snap - On Polyurethane valve insert is used, which reduces operation costs. This is a practical solution as it enables the replacement of only the worn - out insert instead of the entire valve.
- High - Performance Polyurethane
- Imported from the USA, the high - performance polyurethane features:
- High Extrusion/Abrasion Resistance: Extremely perfect, ensuring durability in abrasive environments.
- High Chemical/Corrosion Resistance: Extremely perfect, making it suitable for use in various chemical - laden applications.
- High Pressure Resistance: It can withstand a maximum pressure of 7500 Psi, ensuring reliable performance under high - pressure conditions.
- Temperature - Rated Polyurethane Inserts
- There are two temperature - rated polyurethane valve insert options: 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 operating temperature of their specific application.
- Insert Design for Sealing
- The precisely tapered design of the insert, which matches the seat, provides evenly distributed loading characteristics. This ensures better sealing performance. Additionally, double - angle options of 55°, 45°, or other specified taper designs are available to accommodate 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 allows for 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
- The valve offers a long service life that exceeds API standards, demonstrating its high - quality and reliable performance.
- Polyurethane Material Options
- Customers can choose between domestic high - quality polyurethane and USA high - performance polyurethane. This choice allows for customization based on performance requirements and cost - effectiveness.
- Interchangeability
- The valve is fully interchangeable with major valve types such as Roughneck, FK - N G2, Service Master Drilling, Service Master II Valve, SWND Valve, Cast - N - Place Valve, Mud Max, WM Full Open 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.
- Customized Rubber Option
- Customized replaceable NBR/HNBR rubber is available as an option. This provides further flexibility to meet specific application requirements.
