ABSTRACT:
A gas valve device includes an integral drip leg and filter, positioned upstream from valve means contained therein, for collecting and removing liquid and solid impurities from a gas stream. The drip leg and filter includes a fine-mesh screen of significantly larger cross-sectional area than an inlet opening through which the gas stream enters the gas valve device. The screen is positioned at an angle to cause solid particles to be deflected away from the screen. Clean-out means is located between the inlet opening and the screen for collecting and removing the accumulated liquid and solid impurities. In a preferred embodiment, a detachable cover can be removed to enable cleaning or replacing the screen.
