800D-MTW Interface Float Pilot-Side Mounted

  • Ballasted manual tester verifies integrity of the float ball
  • Side-mount flange fits most brands of filter separator
  • 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 (no red metals)
  • Factory tested

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

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-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
(if equipped)

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.

MAXIMUM PRESSURE: 300 psi (20.7 bar)

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

MAXIMUM FUEL SPECI FIC GRAVITY: 0.85
