Abstract
A dispensing valve for fluids is disclosed which provides for ease of use by requiring 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 that serves to pen and close a plurality of port openings. The valve may be manufactured with a variety of port configurations to provide for the dispensing of fluids of varying viscosities. The valve body and actuator are formed to allow the dispensing valve to be sterilized through high levels of radiation and through high temperature steam and chemical sterilization processes without degrading the valve structure or operation.
