Main Valves

The CIa-VaI Model 100-34 Hytrol Valve is the main (or basic) valve on which all of our aviation fueling control valves are based. It is a hydraulically operated, diaphragm-actuated, globe or angle pattern valve.

Pilot systems are installed on the basic valves to add functions such as flow limiting, surge protection, fuel shut-off, level control, back pressure control, pressure reducing.

All of Cla-Val’s basic valves are manufactured from the finest materials available in the marketplace.  For special material requirements, valve castings can be poured in our onsite foundries.

The diverse configurations, extensive range of material options and the quality of the finished product makes Cla-Val Aviation Fueling Control Valves the most specified valves in the industry.
