- Size Range: 2" to 48" (DN50 - DN1200).
- Pressure Ratings: Class 150, 300, 600, 900, 1500, 2500.
- End Connections: Flanged (RF, RTJ), Butt-weld (BW).
- Operation: Manual (Handwheel/Gear), Electric Actuator, Pneumatic.
Key Technical Advantages of FYL ANSI Gate Valve
1. Superior Sealing Technology
The sealing surfaces of our ANSI Gate Valve are inlaid with high-strength hard alloys (such as Stellite). This ensures the valve is wear-resistant and maintains tight sealing even after thousands of cycles. The wedge-type structure allows for "self-cleaning" during operation, preventing debris buildup.
2. Adaptive Elastic Wedge Design
We utilize an elastic wedge structure that automatically compensates for valve body deformation caused by abnormal loads or temperature fluctuations. This prevents the "wedge-stick" phenomenon common in inferior products, ensuring the ANSI Gate Valve operates smoothly every time.
3. Extended Service Life & Maintenance
The valve seat is designed to be replaceable, allowing for easy onsite maintenance without replacing the entire unit. Our ANSI Gate Valve uses high-quality packing materials to prevent stem leakage, meeting the strictest environmental fugative emission standards.
