Abstract
For precision dispensing of fluids particularly for medical applications, a face valve has a valve member mounted for linear sliding movement across the face of a valve body, which has fluid passages therethrough, between positions in which respectively the valve member seals the ends of the fluid passages at the valve body face and a channel in the valve member connects the ends of the fluid passages. The valve body is of a hard corrosion resistant metal and the valve member is of bearing plastic material, both materials being inert to the fluids being dispensed. The valve is pressed against the face of the valve body by a spring which is oriented in a particular way to optimize valve life.
