Product Q&A

Q:How to choose the size? Is it based on diameter? What sizes are available?

Yes, size is determined by nominal diameter (DN). Common sizes: DN25, DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300, DN350, DN400 and larger.

Q:What media is it suitable for? Water, oil, gas, acid and alkali?

Butterfly valves can be used for water, air, oil, weak acid and alkali. Strong corrosive media requires lined or stainless steel types. High-temperature media needs metal-sealed butterfly valves.

Q:How to judge the quality of a butterfly valve?

Heavier weight usually means better material. Smooth casting without pores or cracks. Smooth operation, no jamming. Good sealing performance. Complete nameplate and identification.

Q:Are there national and industrial standards? Is it a regular product?

Yes, the main Chinese standard is GB/T 12238. Regular products have a nameplate, certificate, and marked pressure, diameter and material.

Q:Is installation difficult?

No, installation is simple. Wafer type is clamped between two flanges; flange type is directly bolted to pipes. Just follow the flow direction arrow.
