Liquip offer the latest innovation in 3 & 4 inch inline air reference pressure operated control valves. 

These valves utilize a direct operating design concept with a control module added to the basic valve. This control module is mounted to the main valve body with one bolt. The new control module gives the unit finer control and eliminates exterior tubing from the valve.

The same control module is used on both the 3 & 4 inch valves. Most of the seals in the main body of the 3 & 4 inch valves are the same, thus minimizing the spares required for any type of maintenance. The control module incorporates a unique bleeder that requires no tools to facilitate bleeding, and it has a vent to prevent fuel from entering the air system, a problem found in several competitors’ valves.

  • Offer up to 16% greater flow rate than competing units, allowing the refuelling of aircraft in a shorter time.
  • Standard 150 lb ANSI inlet and outlet flanges.
  • Victaulic adapters available.
  • Bleeder on module block facilitates simple bleeding of air from the valve — no venting is required once proper bleeding is accomplished.
  • No expensive servos to adjust.
  • Spare parts required for maintenance kept to a minimum due to lack of complicated servos. Many parts are common to bypass valves of same size.
  • Many spares common to Carter brand couplers.
