O'Keefe Controls Co.

At O'Keefe Controls Co., we provide precision flow and pressure control solutions for customers who need reliable performance in compact, sensitive, and demanding systems. Our company focuses on check valves and pressure switches that regulate movement, protect equipment, and monitor conditions across pneumatic, hydraulic, gas, liquid, analytical, medical, and industrial uses. We support OEMs, engineers, technicians, and buyers with components selected for accuracy, fit, and longer service life.

We build our check valve capabilities around dependable backflow prevention, controlled response, and consistent sealing. Our company understands that a small valve can affect pressure stability, system cleanliness, pump protection, and equipment reliability. We help customers consider cracking pressure, flow rate, seal material, body construction, connection style, media compatibility, and installation space so each check valve fits without unnecessary complexity.

Our pressure switches help customers detect, control, and respond to pressure changes within fluid and gas systems. We support applications where switching accuracy, repeatability, set point selection, electrical compatibility, and environmental durability are essential. Our company assists with matching pressure switches to compressors, pumps, instrumentation, test equipment, automation systems, safety circuits, and process assemblies where monitoring helps prevent failures.

We approach each project with practical engineering support, responsive service, and attention to real-world performance requirements. Our company assists with product selection, replacement matching, application review, and configuration guidance for new designs, repairs, and production. Whether customers need a check valve for reverse-flow protection, a pressure switch for system monitoring, or support for a compact assembly, we provide solutions built for dependable control.
