The INVALCO Model CDM is a diaphragm-operated Pressure Switch for pneumatic or hydraulic control. The unit is equipped with one or two snap-acting three-way Micro Valves® to provide on/off output to one or more controlled circuits. Since the Micro Valves® are completely isolated from the diaphragm, and also isolated from each other, various control output pressures and media may be used in the same CDM pilot.
