Abstract
A dispensing valve is disclosed which requires only a minimal force exerted on the valve actuator to maintain the valve in an open position. A resilient valve actuator having the characteristics of a nonlinear spring is provided at an actuator end of the valve body and operatively connected to a plunger, with the opposite end of the plunger mounting a resilient valve seal which serves to open and close a plurality of port openings. The valve is configured so as to allow it to be sterilized through high levels of radiation and through high temperature steam and chemical sterilization processes without degrading the valve structure or operation.
