For reliability, efficiency and proven long life, CECO’s high-efficiency scavenging poppet valves are unmatched. For added quality and durability, the seat and mating parts are fully machined on CNC tools which provide position accuracy to .0005 in. All sealing surfaces are ground flat to prevent leakage between mating parts. Our fasteners are captured by design so that all components are fully retained.

For increased efficiency, the flow area through the poppet valve is increased over the original valve. Our designers have matched poppets, spring loads and lift to provide maximum flow through the valves. The initial installation of CECO scavenging poppet valves ran for over 35,000 hours without maintenance and were still in excellent condition when inspected, and are still running. For over ten years, these valves have been trouble free.
