Product Q&A

Q:Worm gear wafer vs worm gear flange butterfly valve

Wafer: Clamped between pipeline flanges, light, cheap, compact, cannot be buried; Flange: Integral valve flanges, high rigidity, anti-vibration, fit buried pipelines and frequent disassembly maintenance.

Q:Worm gear vs straight lever wafer butterfly valve

Straight lever only fits DN50-DN100 small calibers with low torque; worm gear reducer is required for DN150 and above to reduce operation force and improve safety.

Q:Installation requirements

Two pipeline flanges must be parallel and concentric, bolt tightening force uniform to prevent valve body deformation and seal leakage; worm gear box should be placed above horizontal pipeline, inverted installation forbidden.
