Carbon Steel Flange Butterfly Valve DN250 Price, Water Treatment Engineering Procurement
Carbon Steel Flange Butterfly Valve DN250 Price Reference
Currently, the market price of a carbon steel flange butterfly valve DN250 generally ranges from 600 to 1,500 CNY per unit (excluding tax and freight). The specific price is influenced by the following factors:
Body Material: Ordinary carbon steel (Q235) is more economical. If an anti-corrosion lining (e.g., epoxy resin, PTFE) is required, the price increases by approximately 20%–30%.The main Butterfly Valve product names of China Butterfly Valve Network include:Accumulator(Emergency Off) Quick Off Butterfly Valve,Anti-sediment Butterfly Valve,Flange Soft-sealed Butterfly Valve,Flange Ceramic Hard-sealed Butterfly Valve,High Temperature Butterfly Valve,Groove Butterfly Valve,Fire Signal Butterfly Valve,Telescopic Butterfly Valve.

Brand & Certification: Manufacturers with ISO9001 or water supply product certification charge higher prices but offer better quality assurance.
It is recommended to request at least three quotations and clearly specify parameters such as seat material, flange standard (e.g., GB/T 9119), and pressure rating (PN10/PN16).
Key Considerations for Water Treatment Engineering Procurement
Match Working Conditions: For sewage or particle-laden media, a wafer type hard seal or double-offset butterfly valve is recommended to extend service life.
Quantity & Invoicing: Bulk purchases (10 units or more) may qualify for a 5%–10% discount. Always confirm whether the price includes 13% VAT special invoice.
After-Sales Service: Prioritize manufacturers offering at least 18 months of warranty and having service points nearby.
Summary
The carbon steel flange butterfly valve DN250 price primarily falls within the range of 600–1,500 CNY. For water treatment engineering procurement, comprehensive consideration should be given to seat material, actuation type, and manufacturer qualifications. It is advisable to compare prices through online platforms or directly contact original manufacturers for real-time quotes, balancing initial costs with whole-lifecycle maintenance expenses.
