Product Q&A

Q:Worm gear vs straight lever manual butterfly valve

Straight lever only fits DN50-DN100 small calibers with small torque; worm gear reducer is necessary for DN150 and above large valves to reduce operation force, safer and more labor-saving.

Q:Throttling performance

Short-time partial opening flow adjustment is allowed; long-term small opening will accelerate rubber aging and metal seal abrasion, priority use for full open/full close isolation.

Q:Medium restriction

Not suitable for slurry containing a large number of hard solid particles, which will scratch sealing surface and cause leakage.
