Aircraft fuel shut off valve. Three basic Types of aircraft fuel valves are hand-operated valve cone-type valve and the poppet type valve. Fuel valves used in light general aviation aircraft as fuel selector valves. Gate valves use on transport category aircraft as shutoff valves.
Plug valve consists of machined valve housing. Selector valves are also commonly the poppet type. Aircraft Fuel Shut Off Gate Valve.
With the addition of a computerized flow-control system our aircraft fuel systems shop repairs all types of aircraft carburetors aircraft. Another common flow control valve in aircraft hydraulic systems is the check valve. A check valve allows fluid to flow unimpeded in one direction but prevents or restricts fluid flow in the opposite direction.
A check valve may be an independent component situated in-line somewhere in the hydraulic system or it may be built-in to a component. ALLEN PREMIUM FUEL SHUT-OFF VALVES These premium fuel valves are recommended by Rutan Aircraft as the best fuel valves they have seen. From a pilot perspective you are simply turning the fuel selector on and off which happens to be connected to the fuel shutoff valve.
The pilot doesnt even need to know about the valve so they placard it from the operational perspective in the cockpit and say whether the fuel is on or off. The original pushpull shut off control. This valve is a sig-nificant improvement over the orig nal brass style fuel valve.
The new valve has a stainless steel ball seated in an inert composite seat. This improved design elimi-nates the stiff operation and leaking around. Fuel shutoff valves are a hold over from the days of float style carburetors and necessary on any float style carb system.
With a float style carb when the fuel is on the bowl will fill up until the float floats up and shuts the flow off. The extended handle for the fuel shutoff valve was fabricated from square aluminum tubing and is supported by a bracket attached to the cockpit floor. Note the aluminum tubing connected to the brass T fitting ahead of the rudder pedals.
There is no difference between shutting down the turbine with the throttle and trim or shutting off the manual valve via the transmitter. Once fuel flow is stopped via the solenoid which is an ecu shutdown pump manual valve or blowing a fuel line there is. VACCOs fuel system components include the following.

A distinctive positive snap feel and the highest quality possible. There are two entries and one exit which is tapped. Solenoid-Operated Refuel Shutoff Valve.
When the aircraft is connected to a ground refueling source the fuel management system commands the refuel shutoff valve to close when the selected fuel quantity is reached in conjunction with the refuel control solenoid or pilot-operated float valve. Solenoid Operated Valves provide remote shut-off and draining functions in aircraft fuel hydraulic and water systems. Valves can be normally open or normally closed in the de-energized mode.
WEATHERHEAD FUEL SHUT-OFF VALVE These 3-way Weatherhead valves with 14 female pipe ports feature a Delrin-spool design for smooth operation. Handle mounted on 1-14 inch long shaft. Fuel Shutt Off Valve on a Citabria.
I have a 1969 Citabria 7KCAB and the fuel valve leaks when moved and the handle is directly on the valve. Which my mechanic told me is not legal. I have a rod and u joint to install but found out the tip of the stem on the fuel valve is cracked were to pin goes through it to hold the u joint on.
Check valves can be used as a vacuum breaker low-pressure relief valve or for minimum pressure drop. They are designed with two or four flappers can be manufactured with different materials and range from 1-7 inches. Sleeve valves are different than other aircraft systems in that the valve and actuator can be one and the same.
They can be manufactured for shut-off only or full shut-off configuration. The refuel shutoff valve is designed to operate in conjunction with a refuel control solenoid or pilot-operated float valve. When the aircraft is connected to a ground refueling source refuel pressure and flow are routed to the inlet of the valve allowing the fuel tanks to be filled.
When the selected aircraft fuel quantity is reached the fuel. Valve and the main fuel shut off valve to insure that both valves are open prior to every flight. It requires the manual operation and verification of proper operation of both the wing tank fuel shut off valve and the main fuel shut off valve at every 100 hourannual inspection.
