The efficient design of O'Keefe Controls Co. Bidirectional Fixed Flow Controls features a checked orifice and a precision orifice in parallel within a single construction.

This arrangement offers advantages in applications which require precision flow metering in both directions, where otherwise two flow controls would be needed.

A common example can be found in controlling the speed of single acting, spring-return cylinders in automated machinery. Use of a single Fixed Flow Control can cause excessive speed in the free flow direction which could lead to unwanted slamming. Rather than add a second Fixed Flow Control to eliminate this, the Bidirectional Fixed Flow Control offers a simplified method of providing optimum actuation rates. 

Another benefit to automated processes is the Tamperproof feature of these Bidirectional Fixed Flow Controls. Constructed with two fixed precision orifices, they are not subject to unwanted adjustments. Their flow characteristics will remain consistent and repeatable — meaning processes set to optimum flow rates will continue to operate at those precise settings.
