Product Q&A

Q:Flange worm gear vs wafer worm gear butterfly valve

Flange type has self-contained flanges, high compression resistance, can be buried, stable for high-vibration main pipelines, higher cost and larger axial size; wafer type is clamped between pipeline flanges, light, cheap, compact, only for above-ground exposed pipelines, not allowed for buried backfill.

Q:Seal material selection rules

EPDM: Tap water, fire water, neutral sewage; NBR: oily wastewater; FKM: high-temperature hot water, weak acid/alkali liquid; multi-layer metal composite: steam, flue gas, heat transfer oil with tiny ash impurities.

Q:Installation specification

Horizontal installation with worm gear box upward; pipeline flanges must be parallel and concentric, bolt tightening force uniform to avoid valve body deformation and seal gap leakage.
