When system parameters for process control are well known, engineers and OEMs commonly turn to O'Keefe Controls Co. Tamperproof Flow Controls. Rather than having any adjustable screws or knobs, their tamperproof construction makes them an ideal choice for keeping processes running perfectly at their optimum settings. The result is consistent, unalterable, and worry-free process control during operation. 

Within a single construction, each of O'Keefe Controls Co.’s flow controlling devices consists of an active component, such as a check valve, and a passive component, such as a precision orifice. How they are connected in relation to each other is what determines their performance characteristics. Three types of Flow Controls are manufactured by O’Keefe Controls Co.:

• Checked Orifices
• Fixed Flow Controls
• Bidirectional Fixed Flow Controls

This convenient suite of flow control types can serve a broad array of industrial applications, from fuel line metering with no reverse flow, to air cylinder speed controls and timing circuits, to 3-way valve dampening.
