The following valves arecommonly used in breweries:

1. Butterfly valves are relativelyinexpensive and sanitary valves, mainly suitable for on-off operation. Thedesign of the butterfly valve fea­tures a disk that pivots on a center axis andis sealed with a replaceable valve seat of an appropriate electrometricmaterial. This design allows for the complete cleaning of all product contactsurfaces in a CIP operation when fully opened. Valves of this type are notrecommended for incre­mental flow control, because they generate high shear inthe 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. Diaphragmvalves areused for sanitary, manual flow control, As a flexible diaphragm israised, increasing flow is permitted.

6. Angle-seatvalves arestructurally similar to globe valves but are pneumatically actuated for on-offoperation. They are used in kegging equipment and for similar applications.
