Constant Pressure Modulating Valves
Alfa Laval Constant Pressure Modulating (CPM) valves are pneumatic regulating valves that maintain a constant inlet or outlet pressure in hygienic process lines. Thanks to a quick response diaphragm, these compact valves immediately react to any change in product pressure, adjusting position to keep the pressure at preset values.
CPM valves feature a self-draining design and crevice-free, bowl-shaped valve body with welded valve seat to enable thorough cleaning, thus eliminating potential entrapment areas. The unique diaphragm with PTFE on the lower diaphragm also contributes to excellent cleanability.
Alfa Laval offers three types of CPM valves. Modular design enables the use of different plug sizes and different flow rates between 0.5 and 110 m3/h provide great operational flexibility.
Upon request, some CPM valves can be provided as ATEX-approved valves (group 2 category 3 D&G applications) for use in potentially explosive areas.
