Zhejiang Daye Flange Co., Ltd. is one of the leading manufacturers and suppliers of ss wafer butterfly valve flange in China. With abundant experience, we are committed to providing high quality flanges made in China with competitive price. We warmly welcome you to buy durable ss wafer butterfly valve flange in stock here from our factory. Also, quotation is available.
Flanges for wafer butterfly valves are specially designed to match wafer butterfly valves. Their structure is somewhat similar to slip-on flanges and lap joint flanges, yet there are subtle differences in specific dimensions.
During installation, place the wafer butterfly valve between two flanges and fasten them with bolts.
The SS SS Wafer Butterfly Valve Flange is one of the popular options thanks to its corrosion resistance and wide material availability.Our ss flanges for wafer butterfly valves are manufactured from premium raw materials such as 304 and 316L, produced in accordance with standards specified by customers.

FAQ
Q: What standards apply to flanges for wafer butterfly valves?
A: Dimensions can be produced according to customer requirements. Commonly adopted standards include ASME B16.5 and EN 1092-1. These flanges share the same outer diameter and bolt circle diameter as standard flanges, while only the bore is a non-standard industry size manufactured as requested by clients.
Q: Can standard slip-on flanges be directly matched with wafer butterfly valves?
A: Not recommended. The bore of standard slip-on flanges is larger than that of dedicated butterfly flanges. The standard slip-on flange cannot achieve full sealing effect when used.
Q: Can they be disassembled and reused multiple times?
A: Generally reusable. However, it is recommended to inspect the flanges and sealing gaskets after each disassembly to confirm reusability.
Q: Should ss wafer butterfly valve flanges be matched with metal-seated or resilient-seated valves?
A: SS wafer butterfly valve flanges are recommended for resilient-seated valves. The inner shoulder of the flange can fully compress the rubber seat to achieve excellent tightness.
Q: What is the MOQ?
A: We don't have MOQ,but the more quantity,the price lower.
Q: What are your payment terms?
A: Perfer TT,L/C also acceptable.
Q: What surface finish do you provide?
A: 125-150AARH/,we can also customize accoding to your requirements.
