Curtis Superior Valve is experienced in valve design and can help solve your valve problems. In most cases a standard Curtis Superior Valve will do the job. Or possibly a slight modification of a production unit will answer a specific problem. We will be glad to give you any assistance you may require with your Quick Drain Valve application.
MAINTENANCE / CMM
Curtis Superior Valves are designed for installation in a standard NPT port for NPT threaded valves or an AND-10050 stlye port for UNF threaded valves. Use a sealant on NPT threaded valves or a fuel resistant o-ring of the proper size for UNF threaded valves. Refer to aircraft manufacturers torque specifications for the aircraft in which it is being used. Curtis Superior Valves require no special maintenance. Keep them reasonably clean and replace according to the prescribed synthetic rubber maintenance schedule for the aircraft in which they are used or 10 year usable life per Curtis Superior Valve whichever occurs first. Curtis Superior Valves cannot be OVERHAULED. Replace the entire valve per the maintenance schedule of the aircraft in which it is used or usable life per Curtis Superior Valve should it begin to leak.
Due to the low replacement cost of Curtis Quick Drain Valves versus the cost of replacement seals, breakage of seals in overhaul installations and labor costs, it is not recommended they be overhauled. Replace the entire valve in accordance with the instructions in MAINTENANCE above or should they begin to leak.

Q: Regarding the Curtis Oil Drain Valve for Rotax: Can you go past the recommended 60 to 70 inch/pounds when installing it to make a seal, and if you do are you putting the valve in jeopardy of failing? Had to go to 90 to make a seal
If you went past the recommended torque value I would say you have an issue with a dirty surface area. I would remove and clean all sealing surfaces and retry. Going to 90 in/lb won't hurt the valve.
Q: Will this Curtis Oil Drain valve for Rotax work with both early and late model Rotax engines? Other brands require an adapter for late model engines.
No, this will work with early model Rotax, but late models need adapter CCA-2474 to be used.
Q: Will this Curtis oil drain valve for Rotax fit in a 2010 912 ULS? Or is adapter needed?
Yes, it will fit if the engine is pre-2015. If it is newer, then you will need the adapter 05-03539.
