An insertable, integrally molded, one-piece valve assembly for use in the intake bore of the pump of a liquid dispensing device has a body portion and a top portion which is spaced from the body portion by resilient links. The body portion is pressed into the bore a distance determined by an external stop area, and has a flow passage in which a valve seat is located. The top portion is formed to fit loosely in the bore and abuts against an internal stop area which prevents further inward movement. A compression member extends between the top portion and the body portion and has a valve plug molded on the end which engages the valve seat in normally closed valve relation. The assembly is molded of thermoplastic materials such as polypropylene, polyethylene and mixtures thereof, which plastics are tough and resilient and have excellent 'memory' qualities, and is dimensioned for a press fit in the bore under a controlled compressive stress which is taken up mostly by the connecting links and to a lesser extent by the compression member which biases the valve plug against the valve seat.
