The specific situation is that the valve is used in a winery that processes distiller's grains, and the fluid has certain abrasiveness and corrosiveness.
Operating temperature: 82°C.
Vacuum: 0.47 kg/cm2.
Fluid: 9 to 12% distillers grains solids.
Soda: 10 to 14.
The customer had previously purchased a ductile iron EPDM sealed double flanged butterfly valve, saying that the valve had many quality problems and did not achieve the expected durability.
Therefore, customers need Bundor Valve to make valve selection recommendations for them. The body of the valve is stainless steel and the seat is made of a more durable material than EPDM (as currently installed). The diameter is DN600 and DN900, and the pressure is PN10/16.
Answer: When using valves in wineries containing wine tanks, it is recommended to use stainless steel hard seals. Because if a soft seal is used, the wine tank will get stuck on the sealing surface, which will cause damage to the sealing surface. Therefore, it is recommended to use a double eccentric stainless steel butterfly valve, and the sealing surface can be made of surfacing hard alloy, which is more wear-resistant. In addition, it is also possible to use stainless steel triple eccentric hard sealing butterfly valve.
