Curtis Valves makes a wide range of valves to solve a wide range of problems. They have over 40 standard valve designs engineered, manufactured and tested to exacting specifications, and all manufactured in the U.S.A.
Curtis valves have aerospace, military and industrial applications, and most are listed as ‘Qualified Products’ by the Air Force, Army, Navy and the FAA. Their Quality Systems are compliant and meet International Standard ISO 9001, Military Standard Mil-I-45208, FAA TSO-C76 and FAA-PMA.
Curtis Valves standard designs are spring loaded closed. Valve springs are made from non-corrosive, long lasting stainless steel. Valve bodies and moving parts are manufactured to precise standards with low tolerances and are available in anodized aluminium, brass, cadmium plated brass, and stainless steel. Most seals are made of a specially compounded “cure dated” synthetic rubber to withstand a wide variety of liquids over a broad temperature range. Their valves use a wedge seal design which help to prevent leakage and improve seal life. All oil drain valves use a Viton compound, for long life in high temp. applications.
Curtis 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. Please refer to aircraft manufacturers torque specifications for the aircraft in which it is being used.
Curtis 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 Valves, whichever occurs first. Note – Curtis Valves cannot be overhauled with the exception to the valves listed with replaceable O-rings.
Curtis Valves is experienced in valve design and can help solve your valve problems. In most cases, a standard Curtis Valves will do the job, or a slight modification of a production unit will answer a specific problem.
