Product Q&A

Q:Flange vs wafer butterfly valve

Wafer butterfly valve is clamped between two pipeline flanges, light weight and low cost, suitable for short-distance light-load pipelines; flange butterfly valve has independent flanges at both ends, high stability, fit buried pipelines, high vibration environments and pipelines requiring frequent disassembly.

Q:Can it run long-term throttling?

Short-time partial opening adjustment is allowed; long-term small opening will cause high-speed medium friction to accelerate rubber aging and metal seal abrasion, priority application is full open/full close isolation.

Q:Pressure temperature limit

Standard ductile iron EPDM model stable at PN10/PN16, 0-80; triple eccentric metal hard seal can reach PN100, 600 high temperature.
