Safety Solutions for Fuel Filling

The Hydrau-Flo® Safety Solutions for fuel Filling is a safer, cleaner and more reliable fuel filling valve arrangement which removes the risk of overfilling, spillage and tank rupture while minimizing safety and environmental hazards associated with fuel transfer.

Using conventional systems, overfilling, spillage and tank rupture can be common occurrences. At 265 gallons per minute, every second of spillage equates to more than 4 gallons of diesel wasted and released into the environment while the cost to repair or replace ruptured fuel tanks is significant in terms of materials, labor and equipment down time.


  • Flows up to 265 gal/min
  • Fully mechanical design integrated with hydraulic principles
  • Eliminates blockage and electronics failure
  • Cannot be over-ridden
  • Reduces costs associated with fuel wastage

Hydrau-Flo® valve system:

  • prevents overfilling
  • prevents fuel spillage and wastage
  • is industry’s current best practice in refueling
  • removes the risk of tank rupture due to pressure build up during and after filling
  • minimizes the risk of fire as a result of fuel spillage
  • reduces costs associated with fuel wastage and equipment damage
  • significantly improves safety and environmental outcomes

The main features of Hydrau-Flo® (HF) compared to the competition:

  • HF is a genuine fast filling valve that delivers higher flow rates than the competition (the competition claim 150 gpm max through the valve, we believe this to be closer to 92 gpm – 105 gpm based on the orifice);
  • HF comes with an 18 month warranty compared with 12 months for the competition;
  • HF has fuel surge protection for machinery on the move- this creates a positive seal against fuel trying to escape to atmosphere. The competitive system does not contain this feature;
  • HF contains roll over protection (same features as fuel anti surge) which in a machine roll over or inclination will stop fuel escaping from the tank. Thecompetitive system does not contain this feature;
  • HF is robust and durable. The competition is made from plastic which does not match the quality offering by CAT;
  • HF is universal- it works with Banlaw, Wiggins and Fast Fill nozzles;
  • HF can be configured for internal or external pilot lines, providing a much broader scope for installation,the competition is only internally piloted;
  • HF does not need a tiny bleed hole to dissipate pilot line fuel once shut off occurs. The competition’s system uses this feature and should that tiny hole become blocked, hydraulic lock will occur meaning the fuel tank cannot be refilled until the system is repaired;
  • HF has a superior surface area for air to vent to atmosphere. The competition uses a diaphragm at the float control valve opposed by a light spring. If the system fails, fuel is easily directed to atmosphere
  • The competition’s system, both the fuel filling valve and float control valves use diaphragms as the piston mechanism. HF uses a stainless steel piston and teflon seal ring- excellent for extreme temperatures;
  • HF uses anti surge tanks on known assets where fuel surge is significant (enough to easily defeat the competition’s system and cause a spill) and the anti surge tanks are integrated with the HF kit design IE 992G;
  • HF can be used with dual filling arrangements, multiple tank configurations and unique installations which the competition cannot easily accommodate due to the internal pilot line limitation.
  • HF’s configurability with internal or external pilot lines comes without added expense.
