This NEW ultra-light Jet-Tronics JD-Valve has three additional functions to the normal Double valve.
1. Speed Control Function
IN and OUT speed of the units can be electronically throttled in both directions independently.
This prevents the gear slamming against the fuselage and/or wing.
The throttle action starts strongly at the beginning and reduces at the end of the throttle time.
This causes an even speed mouvement of the gear.
About 90% of air leaks occur between valve and cylinders because this is where the highesterror sources exist. (Junctions, connections between fuselage to wing and cylinders). In unitsthat lock mechanically, there is no need to keep the system pressurised. This reduces the
chance of lost pressure, so full pressure is available for delivering the gear IN or OUT again.
If this option is chosen the valve shuts off the pressure after 15sec, which is enough time for
most units to operate.
3. Manual Operation
Just in case the transmitter is not available it is possible to activate the valve manually.
This valve is attached directly to the receiver to control undercarriages with double acting cylinders
It replaces the mechanical valve AND the servo plus linkage:
-The bottom measurements without connections aren't greater than an usual mechanical valve (L=34mm, B=28mm) in which the room is dropped for servo and linkage. The height is 29mm.
-The connections consist of high-quality metal fast connections for tubes with 3mm of outside diameter.
-The speed of delivering in and out of the undercarriage can be throttled. This happens by using restrictors which are attached at output 3.
-In the off condition both valves are closed while only of the valves is open when operating, dependtly on the position of the transmitter function.
-the remember function prevents that the undercarriage unintentionally works, if the transmitter function should be in an other position as on shutdown.
-The current consumption of 100mA at 5volts is by 50% lower than at the usual 1watt valves.
-Viton sealing make the valve insensitive toward most oil sorts.
-The air throughput is around 40% higher and therefor very well suitable also for big undercarriages.
