Low Pressure Electronically Controlled Valve

Reference#: P01554


A low-pressure valve enabling precise control of a fluid flow rate through the valve during cyclical operation of the valve. The valve is useful for controlling air delivery to a patient as part of a portable ventilator. The valve comprises a housing having an inlet 16 and two outlets 18 and 20. A wiper plate 22 and an orifice plate 24 are disposed inside of the housing. Transverse movement of the wiper plate 22 relative to the orifice plate 24, powered for example by a servomotor 34, simultaneously and alternatively covers and uncovers various openings 26 in the orifice plate 24. The total flow through the valve is thereby divided between the two outlets 78 and 20.
