Valves control the product flow, so are called the on and off switch in the brewery. The mechanical parts control the direction of the liquid, gas, and mixture. Valves to be applied in the distilling process depend on the media and the processing phase. It is good to get familiar with the design and differences to be considered to ensure that proper beer flow is controlled without affecting its taste.
Sanitary valves for brewing beer can be ordered from a reliable source like Flowtrend. You will need to choose different quantities of mediums with varying temperatures to transfer or mix between tanks, fermenters, and kettles. Some types of valves can be advantageous but some need to be avoided.
Main types of brewery valves
The butterfly valve has a good hygiene design with tight seals and can be cleaned easily. It is unsuitable for high pressure because it has an internal stem that rotates the wafer or disc that can hinder the flow. Great for blow-off arm, CIP line, bottom bow or racking arm.
The electromagnetic field gets created with an electric coil that pressurizes the plunger to open the flow and closes when power is cut off. The response is very quick but is not good for highly viscous flow. For safety reasons implemented for glycol or gas lines or automated bottling process.
A rotary ball rotates to open and close the valve. The flow is unobstructed and there is no concern about leakage. Due to contact from the floating ball, there is the possibility of a hygiene issue. Implantation for thick mediums, gas lines, water lines, or carbonation stone.
A needle-point plunger movement controls the flow precisely and can be applied for water and gas lines to get the strike temperature.
A gate moves perpendicularly up and down in the piping to close and open it. It allows the media to flow without any hindrance. Gate valve is great for water faucets but cannot handle high-pressure applications because flow cannot be controlled precisely.
The diaphragm and stem are moved down to seal against valve body and so is a hygienic solution for controlling the flow. A great option for heat exchangers.
The plunger and stem move up and down to close and open, thus flow gets better regulated in comparison to the gate valve. It can be applied in mixing or water faucets.
The valve design has to be either manual or automatic. The preferred material is stainless steel as it can deal with a harsh cleaning agent and is tough. The end product taste does not get affected. For cooling, circuit or water lines use brass housing. The seal is EPDM that can handle 130 °C. For high-temperature Teflon is recommended. Common valve connections are tri-clamp, thread, and flange for a brewery.
