ABSTRACT:
In a gate valve which has a pressure equalizing valve located in a chamber formed in its valve member, there is provided a vent passage opening from an expansion compartment which is located above the pressure equalizing valve, through the downstream side of the valve member such that any pressure buildup in the expansion compartment resulting from the opening of the pressure equalizing valve may be vented to the downstream side of the valve member and will not cause the pressure equalizing valve to move to its closed position.
