OPERATION AND CHECKOUT

Operation

The V4297S is a normally open valve. The valve closes when
it is energized, and opens when the power is removed. It
provides the vent function in a double block and bleed
application. The V4297S is open when the two Safety Shutoff
Valves (SSOV) are closed, and is closed when the two SSOV
are open.
