The ControlAir Type-100M Motorized Air Pressure Regulator is designed to provide precise pneumatic control by use of an electrical signal. This highly accurate device is well suited for pneumatic control of a system from a remote location. Utilizing two tandem synchronous AC Motors, each having it's own set of leads, but operating through a single output shaft, direction of rotation is dependant of which set of leads power is applied to. The motor is coupled to ControlAir's Type-100, which is a high precision, multi-stage air pressure regulator with low power requirements.
OPERATION:
When no electrical power is supplied the regulator maintains a precise set point despite variable supply pressure conditions and flow rates. When power is applied to the motor the regulator pressure output changes intermittently.
