Butterfly valves are sanitary valves and mainly suitable for on-off operation. The price of butterfly valve is relatively inexpensive.The design features of the butterfly valves are that pivots on a center axis like a disk and is sealed with a replaceable valve seat of an appropriate electrometric material. This design allows for complete cleaning of all beer brewing equipment contact surfaces in a CIP operation when fully opened.
What are some valves commonly used in beer brewing breweries?

a. Butterfly valves are sanitary valves and mainly suitable for on-off operation. The price of butterfly valve is relatively inexpensive. The design features of the butterfly valves are that pivots on a center axis like a disk and is sealed with a replaceable valve seat of an appropriate electrometric material. This design allows for complete cleaning of all beer brewing equipment contact surfaces in a CIP operation when fully opened. Valves of this type are not recommended for incremental flow control, because they generate high shear in the product. Butterfly valves can be with lockout features.


b. Ball valves contain a rotating ball with a hole formed through the center to control flow.They are not considered sanitary in design for product use; salespersons claiming them as such should be questioned. The features of ball valves are generally inexpensive, long service life, suitable for high-pressure applications, and good for on-off functions. But they are not recommended for regulating flow.

c. Globe valves are excellent at controlling flow. Operationally, a sealing disk controls the restriction of the flow path. Globe valves are especially prevalent in  steam and water applications and generally non-sanitary in design.

d. Gate valves interrupt flow by moving a rigid gate across the liquor flow. Gate valve should be used only for on-off, inexpensive and non-sanitary applications rather than flow control. Large models are used for spent grain applications in beer brewing breweries.  

e. Solenoid valves are on-off valves that are actuated by energizing a small electromagnetic coil. When activated, the coil allows a diaphragm to move, thus permitting fluid flow. They are commonly used for glycol jacket control and small pneumatic control duties.

f. Diaphragm valves are used for sanitary, manual flow control. As a flexible diaphragm is raised,the flow increasing is allowed.

g. Mix-proof matrix valves are both very sanitary and very expensive and are commonly used in large scale breweries. They are generally installed in a matrix of piping and, when closed, act as a block -and -bleed set, so that if a single seal were to fail, liquor would leak to the valve exterior, not into the connecting pipe.

h. Plug valves are an older style of valve still in use in sample cocks in many beer brewing breweries. Disassembly is required for CIP. 

i. Angle-seat valves are structurally similar to globe valves but are pneumatically actuated for on-off operation. They are used in brewing beer equipment commonly.
