800D Interface Pilot-Side Mounted

  • Side-mount flange fits most brands of filter separators
  • Pilot float “rides” the interface between water and fuel
  • Four-way control to actuate discharge slug valve and/or automatic water drain valve
  • Uses time-proven 800 pilot block (see Model Sheet 800)
  • Stainless Steel pilot and float assembly
  • Manual tester standard
  • Factory tested

The Model 800D is a side-mounted filter separator float that allows only the discharge of clean, water-free fuel from the filter separator.   The three models are as follows:

PILOT BLOCK PORT CONNECTIONS (All ports 1/8” NPT)

POWER: Filter separator vessel pressure

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 is counter-weighted so that it will float in water, but sink in fuel.   Depending on the water level in the filter separator, the 800D actuates the other control components in the system as follows:

FLOAT POSITION

DISCHARGE (SLUG)
VALVE

WATER DRAIN VALVE
(if equipped)

DOWN (No Water)

OPEN

CLOSED

MEDIAN (Rising Water)

OPEN

OPEN

UP (High Water)

CLOSED

Actuating the manual tester will raise the float to the median or up positions, confirming the proper operation of the pilot, slug valve, and/or the water drain valve.

MAXIMUM PRESSURE: 300 psi (20.7 bar)

OPERATING TEMPERATURE: 32°-120°F (0°-49°C)

MAXIMUM FUEL SPECIFIC GRAVITY: 0.85
