Manual Dual-Valve With Speed Control Function and Air-failsafe function
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 movement of the gear.
2. Air-Failsafe-Function About 90% of air leaks occur between valve and cylinders because this is where the highest error sources exist. (Junctions, connections between fuselage to wing and cylinders). In units that 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.
