Item description from the seller

707 fuel/bleed‑air control module – vintage 1960s Pricing is for one valve assembly. You can choose the exact unit you want from the variation menu - just message me. Each unit is shown individually with its own data plate information. For sale is a rare slide gate shut off valve assembly built by Wm R Whittaker Co Ltd. Each unit dates to the first quarter of 1962 and consists of a WA8000 electric actuator mated to a WE4800 1 1/4E manually operated slide valve. These assemblies were designed for Boeing C 135 series aircraft and early 707 derivatives where they controlled fuel or bleed air flow. The WA8000 actuator operates on 18 to 30 volt DC and each unit has been tested at about 15 volt and cycled the valve smoothly. The valve body features a lever marked OPEN and CLOSED so you can see and manually position the gate when the motor is not powered. The mechanical slide moves freely on all units listed here. These assemblies have been stored as surplus and show normal storage wear. Although they operate on a bench test they are offered as collectibles or cores only and not for installation on a flying aircraft. It is up to the buyer to perform any further functional testing or overhaul. Sale includes the actuator and valve assembly with the original data plates.
