Wafer Type Soft Seal Butterfly Valve DN65 Price, Water Supply Pipeline
Factors Affecting the Price of Wafer Type Soft Seal Butterfly Valve DN65
Currently, the price of a wafer type soft seal butterfly valve DN65 generally ranges from RMB 180 to RMB 550. The specific price is influenced by the following factors:
Valve Body Material: Cast iron costs approximately RMB 180-280, ductile iron (QT450) costs RMB 260-380, and stainless steel (304) costs RMB 450-550.
Disc Material: Ordinary galvanized plate costs RMB 180-250; stainless steel disc (304/316) offers better corrosion resistance and is 40%-60% higher in price.
Seal Material: EPDM is the standard seal for water supply, offering excellent aging resistance; NBR is suitable for oily media, with a similar price.
Connection Standard: The wafer type structure itself is low in cost, but different flange standards (PN10/PN16) may affect the cost of matching accessories.The main Butterfly Valve product names of China Butterfly Valve Network include:Electric Soft-sealed Wafer Butterfly Valve,Fire Signal Butterfly Valve,Flange Soft-sealed Butterfly Valve,High Temperature Butterfly Valve,Pneumatic High Vacuum Butterfly Valve,Quick-installed Sanitary Butterfly Valve,Three Eccentric Multi-level Metal Hard-sealed Wafer Butterfly Valve,Worm Gear Soft-sealed Flange Butterfly Valve.
Advantages for Water Supply Pipeline Applications
The wafer type soft seal butterfly valve is optimized for water supply conditions and offers the following significant advantages:
Bidirectional Sealing: The soft seal seat achieves bubble-tight zero leakage, ensuring no water leakage or contamination.
Low Flow Resistance: The disc has a smooth flow path, resulting in almost no pressure loss when fully open, suitable for long-distance water transmission.
Corrosion Resistance: The EPDM seal and epoxy resin coating on the valve body effectively resist residual chlorine corrosion in tap water.
Easy Installation: The wafer type structure requires no flanges on both ends; it can be fixed simply by inserting bolts through the wafer holes, saving installation space and time.
Purchasing Suggestions
It is recommended that users select the valve body and disc materials based on the working pressure (PN10/PN16), pipeline layout, and opening/closing frequency. For water supply applications, the combination of ductile iron valve body + stainless steel disc + EPDM seal is recommended. When purchasing, confirm that the valve complies with GB/T 12238 standards and check that the internal and external coatings of the valve body are uniform and free of pinholes. It is advisable to request quotes from at least three professional valve manufacturers for comparison, and prioritize products with a drinking water hygiene safety product license.
