Auto Re-circulation on a Refueller to control the pumping
pressure of Air Crafts.
Solenoid Override or Pneumatic Override to safeguard the
system. This can be operated remotely to re-circulate full flow.
When installed in Main line, it prevents upstream pressure
dropping below preset value.
When installed on a By-Pass line, it controls main line pressure by
relieving excess pressure in By-Pass/sump.
Ideal for pump by pass to protect the downstream equipments.
Relief pilot (VT16) is normally closed due to spring tension.
With increase in upstream pressure above set value, Pilot (VT-16)
opens which makes Main Valve to open fully.
Spring Range: Standard: 20-200 psig. Optional: 5-30 psig.
