6. Front cover and indicator cover

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.
