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.


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.

Exact product as removed from aircraft. No problems. If you need it quick don’t use postal service!

Shipped and arrived quickly...unfortunately, Curtis no longer makes replacement rubber rings for the drain, for safety reasons, so finding the complete drain and getting it in hand quickly was a real plus...

Q: What is the proper o-ring to use with CCA-3400? I cannot find the one listed in the Beechcraft parts manual anywhere.

The orings are not replaceable, you would need to replace the whole valve if it is leaking.
