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 stainless steel, anodized aluminum, brass, and cadmium or nickel plated brass. Most seals are made of a specially compounded “cure dated” synthetic rubber to withstand a wide variety of liquids over a broad temperature range. Our valves use a wedge seal design which help to prevent leakage and improve seal life.
Typically used on some Cessna 172, 177, 182 (R/RG), 206, 207, 210 and Cirrus aircraft models, among other aircraft using valves with the same valve length & thread size. (Applicability varies), For questions regarding applicability, please don’t hesitate to contact us!
