Overview:

Curtis Superior Valve Co. Inc. has produced, engineered, manufactured, and tested aircraft valves to exacting standards since 1944. They have many standard valves to solve a wide range of problems.

• Corrosion resistant, stainless-steel springs
• Specially compounded "cure dated" synthetic rubber seals to withstand a wide variety of liquids over a broad temperature range
• Unique wedge seal design prevents leakage.

Maintenance / CMM:

Curtis Superior Valves are designed for installation in a standard NPT port for NPT threaded valves or an AND-10050 style 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.

Specification:
Lycoming Oil Drain Valve

IMPORTANT VALVE INSTRUCTIONS:
Most Curtis Superior Valves do not use O-rings unless noted in description, we use a special flat molded seal, therefore can not be overhauled. If the valve is leaking clean the seal area and recheck for leakage, if the valve continues to leak replace the entire valve per the aircraft maintenance schedule. Curtis valves have a life expectancy of 10 years under normal operating conditions.

We recommend the following thread sealant:
1. Pipe threads: 1/4" Teflon tape, Permatex 80632 Thread Sealant, Loctite 592 PST Pipe Sealant
2. Straight Threads: Lubricating Oil
