Ground fueling product
Controls is the largest domestic producer of fueling components for hydrant service vehicles, refuelers, and over-the-road tankers.

Products include:
• Underwing fueling nozzles and disconnects
• Hydrant valves and couplers
• Self-sealing quick disconnects
• Bottom loading components
• Fuel level sensors

Quick disconnects
Controls' Zero-Aire® quick disconnects and fluid couplings provide the capability to connect and disconnect fluid transfer lines without leakage, spillage, or air inclusion. The division's quick disconnects feature ground and lapped mating faces and a unique, patented valve-cartridge design that prevents leakage after disconnection. Both high and low-pressure designs include fast-acting ball lock, threaded or rack and panel configurations.

Industrial products

Valves

Controls sells a line of high-speed fuel control and shutoff valves that operate in less than 100 milliseconds. These designs feature either hydraulic or electric actuation, can handle discharge temperatures of 1100°F and pressures up to 1000 psi.

The division provides complete electro-hydraulic or all-electric fuel skids for natural gas and liquid fuel powered aero-derivative engines used in power generation and pipeline pumping installations. These systems are certified to Canadian Standards Association ("CSA"), Comité Européen de Normalisation Electrotechnique ("CENELEC") and United Laboratories ("UL") Zone 1 explosion-proof levels.

Additionally, Controls is approved on base and DLE (Design Low Emissions) versions of the Rolls Royce RB211 and General Electric LM-2500, 2500 plus, and LM1600 engines.
