Abstract
A gas and vacuum system is disclosed, and, in particular, an area valve service unit configured to provide local isolation of individual parts of a gas and vacuum system that may be required for installation, maintenance, or in the event of an emergency. The area valve service unit can have one or more shutoff valves, each of which has an associated access panel with a movable access panel door.
Claims20
An area service valve unit for a gas and vacuum system, the area service valve unit comprising:
- a cabinet defining an interior volume, the cabinet including a first access panel coupled to the cabinet, the first access panel being movable between an opened position and a closed position relative to the cabinet, the first access panel having an opening formed therein;
- a first shutoff valve being in fluid communication with the gas and vacuum system, the first shutoff valve being located in the interior volume and behind the first access panel, the first shutoff valve having a first handwheel that can be manipulated to open and close the first shutoff valve, the first handwheel being aligned with the opening of the first access panel;
- a first access panel door mounted to the first access panel and covering the opening formed in the first access panel, the first access panel door being movable between a closed position and an opened position;
- and
- a first cover plate located between the first handwheel and the first shutoff valve, wherein the first cover plate is bendable to facilitate a user to access a component behind the first cover plate without removing the first handwheel or the first cover plate after the first access panel door is opened.
