The front cover of P5 is secured to the pneumatic unit with four captured screws and sealed
with an O-ring 1. The O-ring can be looped over notches 2 in the front cover to allow for
drainage. There are eight locations on the front cover where the O-ring can be looped. This
O-ring system is common to the Pneumatic unit , I/P unit and Feedback unit in the PMV
Valve Control System P5. This unique sealing system allows for complete sealing or draining
of the units by changing the position of the O-ring.
The indicator cover 3 is O-ring sealed and secured by a bayonet coupling. The indicator
cover is also used to secure the identification cover 4.
To remove the indicator cover turn it slightly counterclockwise until it loosens. Identification
cover and O-ring 5 are now removable.
When installing indicator cover and identification cover make sure that the O-ring is properly
engaged.
