Manley® Valve

Since its introduction in 1971, the Cook Manley valve has set standards that have revolutionized the compressor valve industry. The Manley valve uses radiused, concentric discs to provide more efficient gas flow, and thermoplastic material to improve sealing. The design is particularly well-suited for high-pressure applications and can resist damage from foreign debris for durability in harsh conditions. Learn more at
