The following valves are commonly used in breweries:
1. Butterfly valves are relatively inexpensive and sanitary valves, mainly suitable for on-off operation. The design of the butterfly valve features a disk that pivots on a center axis and is sealed with a replaceable valve seat of an appropriate electrometric material. This design allows for the complete cleaning of all product contact surfaces in a CIP operation when fully opened. Valves of this type are notre commended for incremental flow control, because they generate high shear in the product. Butterfly valves can be specified with lockout features .
2. Ball valves contain a rotating ball with a holeformed through the center to control flow. They are especially prevalent in gasdistribution and water-piping applications. They are not considered sanitary indesign for product use; salespersons claiming them as such should be questioned.These valves are generally inexpensive, long lived, and suitable forhigh-pressure applications. They are very good for on-off functions but not forregulating flow.
3. Globe valves are excellent atcontrolling flow. Operationally, a sealing disk controls the restriction of theflow path. Globe valves are often found in steam and water applications and aregenerally non-sanitary in design.
4. Solenoid valves are on-off valves thatare actuated by energizing a small electromagnetic coil. When activated, thecoil allows a diaphragm to move, thus permitting fluid flow. They are oftenused for glycol control and small pneumatic control duties.
5. Diaphragm valves are used for sanitary, manual flow control, As a flexible diaphragm is raised, increasing flow is permitted.
6. Angle-seat valves are structurally similar to globe valves but are pneumatically actuated for on-off operation. They are used in kegging equipment and for similar applications.
