BI-METAL LINER & Seat & Spare Parts – Buyer FAQs
What is a 4-Web Valve & Seat?
A 4-Web Valve & Seat is a heavy-duty valve system engineered for extreme-pressure mud pumping applications. Its unique four-support-web design provides superior structural stability and alignment under high cyclic loads, while the integrated seat ensures leak-free sealing in high-temperature drilling environments (up to 350°F/177°C).
Why choose 4-Web over other valve designs?
- Enhanced Durability: 4-web geometry distributes stress evenly, reducing cracking/peeling.
- Thermal Stability: Optimized for sustained performance in high-temperature wells (e.g., geothermal, deep drilling).
- Reduced Turbulence: Streamlined flow path minimizes erosion from abrasive mud.
- Easy Maintenance: Snap-in seat design allows quick replacement without disassembling the pump.
What materials handle high temperatures?
Component | Material | Temperature Limit |
---|---|---|
Valve Body | Forged AISI 4140/4130 Steel | 350°F (177°C) |
Sealing Surface | Stellite 6® or Tungsten Carbide | 400°F (204°C) |
Seat Insert | Nitrided Steel + Ceramic Coating | 350°F (177°C) |
How does the 4-Web design improve valve life?
- Stress Reduction: 25% lower peak stress vs. 3-web designs (FEA-verified).
- Thermal Expansion Control: Web slots accommodate thermal growth without distortion.
- Debris Resistance: Self-cleaning groove design prevents particle jamming.
What applications suit 4-Web High-Temperature valves?
- Ultra-Deep Drilling (>15,000 ft)
- HTHP (High-Temperature High-Pressure) Wells
- Geothermal Drilling
- SAGD (Steam-Assisted Gravity Drainage) Operations
