O’Keefe Controls Co. versatile Ball Type Check Valves are used across a wide variety of smaller industrial applications to effectively prevent reverse flow.

Some examples include use with expansion valves for pressure relief applications, in multi-line dispensing and fill operations, and in industrial spray-nozzle applications to minimize dripping. They can also be used to prevent reverse flow through solenoid valves, especially in higher-pressure applications.   

These durable check valves feature all-metal bodies in brass or stainless steel, with a choice of 303 SS or elastomeric balls. Many configurations are offered for easy installation into most systems. Connections include NPT, 10-32 UNF and compression tube, in a variety of sizes. Offered with or without springs, many cracking pressure options are also available.
