Control valve backlash
WebDeadband regions can be used in control systems such as servoamplifiers to prevent oscillation or repeated activation-deactivation cycles (called 'hunting' in proportional control systems). A form of deadband that occurs in mechanical systems, compound machines such as gear trains is backlash . Input and output of the deadband operator.

WebFeb 24, 2024 · Place the feeler gauge in between the valve eccentric and the valve. Now, using the stiff wire or wrench, rotate the valve eccentric til it makes contact with the feeler gauge. You want the feeler gauge to have a slight drag on it when you move it in between the eccentric and the valve.
WebJun 25, 2024 · This is zero lash. To set preload, merely tighten the adjuster nut another half-turn after zero lash. If you are setting the lash on a mechanical lifter camshaft, use the appropriate feeler gauge between the valve tip and the rocker arm and adjust the lash until there is a reasonable tug or pull on the feeler gauge. WebThe dead band from valve backlash and the stick slip from stiction will cause limit cycling in loops with two or more and one or more integrators, respectively. These limit cycles are greatest for large rotary valves and particularly for on-off valves being used as throttling valves. For processes with high process gains (e.g., pH),
