BI-METAL LINER & Seat & Spare Parts – Buyer FAQs
1. What is the structural feature of the 4-Web Valve & Seat?
The 4-Web Valve & Seat is a center-guided valve system characterized by its 4-web design, which enhances stability during high-pressure operation. It typically includes a replaceable snap-in insert (available in standard and high-temperature versions) and is oxide-coated to prevent corrosion during storage. The valve body and seat are often made of forged steel or 20CrMnTi material for durability, ensuring compatibility with API standards for seamless integration with mud pump systems
2. What temperature and pressure ranges does the 4-Web Valve & Seat support?
This valve system is engineered to handle extreme drilling conditions, with standard versions suitable for temperatures up to 121°C (250°F) and high-temperature variants rated for higher thresholds (specifics may vary by manufacturer). Pressure resistance typically aligns with high-pressure mud pump requirements, ranging from 5,000 to 7,500 psi (34.5 to 51.7 MPa), making it ideal for oil & gas, mining, and construction applications involving high-solids mud
3. How to maintain and replace the 4-Web Valve & Seat?
Maintenance involves regular inspection of the valve insert, seat, and coating for wear or corrosion. The replaceable snap-in insert allows for quick更换 without disassembling the entire valve body, reducing downtime. Ensure proper torque when reinstalling to prevent leaks, and use manufacturer-recommended lubricants for threaded connections. Storage in dry conditions is advised to preserve the oxide coating’s corrosion resistance
4. What applications are 4-Web Valves suitable for?
They are ideal for hostile drilling environments including:
5. How to select the right 4-Web Valve for a mud pump?
- Pressure/Temperature Ratings: Choose standard (ambient) or high-temperature (HT) inserts based on well conditions.
- API Compliance: Ensure compatibility with API-standard valve seats.
- Pump Model: Match dimensions to specific pump models (e.g., F-1600, 16P160).
- Material Selection: Urethane inserts for abrasion resistance; metal alloys for extreme pressure
