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.

OVERHAUL

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.

Reviews

Curtis holds PMA on the CCB-37000 Drain Valve for certain Lycoming engines. See their website. Slightly shorter than the one it replaced. Looks like a quality product. Would appreciate recommended thread sealants.

Great quality and the spring tension is MUCH BETTER than the blue aluminum ones. My blue one leaks like a 99 dodge truck. That’s why I purchased this one.

This fit my Comanche 250 perfectly. The only disadvantage is that there was no allowance for safety wiring the unit in place.

The Curtis quick-drain valve looks like an excellent piece of engineering, and would likely be an excellent investment, however, it will not fit in a Cessna 210. There is insufficient clearance for the valve and the retracted nose wheel.
