| FAQ
1. Key Differences: Butterfly Handle Ball Valve vs. Two-Piece Wire Ball Valve"
| Main distinction | 2PC threaded ball valve | 2PC threaded butterfly handle ball valve |
| Structure design | Two parts valve body Suitable for small-diameter vallve Low cost | Two-piece structure Short size, low torque, space saving 90 degree rotation operation |
| Operation mode | The pressure resistance of sealing ring material must be considered, and the ball may deviate under high pressure. | Excellent selaing and flow capacity Small flow resistance |
| Application | home decoration and construction, or small pipelines such as steam pipes | Engineering pipeline system |
| Sealing performance | Elastic sealing | Sealed PTFE mostly |
| Maintenance & cost | Anti-static, fireproof structure design but complex maintenance | Easy to disassemble |
2. Will a butterfly handle ball valve deflect under high pressure?
1. Floating Ball Design: The floating ball in butterfly handle ball valves displaces under pressure, sealing tightly against the outlet end, preventing deviation.
2. Stem Bearing: High-performance valves feature sturdy stem bearings that resist deflection from temperature and mechanical loads, reducing pressure-induced deviation.
3. Stem Design: A one-piece, high-strength stem design ensures actuator compatibility and stem stability, minimizing high-pressure deflection.
4. Pressure Resistance: Some models are rated for 720 psi (49.6 Bar) and maintain zero leakage after extensive testing, indicating robust high-pressure performance without deflection.
