ABSTRACT:
In a gun for dispensing a fluid component, a valve assembly controls the dispensing of the fluid component. The valve assembly includes a needle or valve member and a cup assembly having a passage for receiving the needle assembly. A channel system allows flow of the component through the passage past a seal. An actuator assembly may be provided for providing relative movement between the cup assembly and the needle assembly from a valve-closed position to a valve-open position in which the seal is located upstream from a downstream end of the channel system to permit flow of the component through the passage.
