A butterfly valve is used to open, close, and regulate flow in pipelines.
Compared with other valves, it is compact, lightweight, cost-effective, and operates quickly (90° rotation to fully open/close). It is widely used for large-diameter pipelines.
2. 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.
3. 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.
4. 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
5. 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.
6. 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.
7. How to choose cast iron, cast steel, stainless steel?
Cast iron: For water, air, normal temperature and pressure, low cost
Cast steel: For steam, high temperature, medium and high pressure
Stainless steel (304/316): For corrosive media, food, pharmaceutical applications
