DN300-1800（12”-36”）
Product description :
DESN Processing and conveying butterfly valves are widely used in the production of fluid, once the sealing ring caused by leakage, all of the butterfly valve can be in the pipeline directly to the sealing epoxy resin injection repair, without disassembly.
Characteristic ：
- Minimum coating thickness 250 u M.
- No porosity (300W pool spark test).
- With high precision metal (minimum 12N/mm -).
- Sealing material EPDM maximum use temperature of 121 degrees C (250 degrees F).
- E-Lok sealing ring design, will not affect the seal due to impurities, rubber does not require pressure; a unified nature to ensure a long life, fully credible adjustability or replacement.
- In many cases, the sealing ring can be replaced directly in the pipeline. Rubber sealing surface mirror in the butterfly plate, thereby reducing the corrosion of the pipeline caused by the valve performance.
- Valve in accordance with the AWWA505 standard life cycle test, providing more than 500 thousand reliable life requirements.
- DN1000 more than the flange butterfly valve with the circulation design, improve the strength of the butterfly plate to reduce the weight of the board, so as to reduce the loss of customers and save energy.
