ACCELERATOR VALVE: Bonnet of accelerator pilot on discharge slug valve
WATER DRAIN: Bonnet of automatic water drain valve
EXHAUST: Atmospheric drain line
OPERATION
The float of the 800D-MTW is counterweighted so that it will float in water, but sink in fuel. Depending on the water level in the filter separator, the 800D-MTW actuates the other control components in the system as follows:
|
FLOAT POSITION |
DISCHARGE (SLUG) VALVE |
WATER DRAIN VALVE |
|
DOWN (No Water) |
OPEN |
CLOSED |
|
MEDIAN (Rising Water) |
OPEN |
OPEN |
|
UP (High Water) |
CLOSED |
OPEN |
Actuating the manual tester will remove the counterweight from the float arm. This allows the float to rise, confirming the proper operation of the pilot, slug valve, and/or the water drain valve, as well as the integrity of the float ball valve itself.
