Again, we may express the two valves’ exclusive relationship in the form of a graph, with colored stripes representing valve opening A few different modes of control valve sequencing are commonly seen in the industry Learn split range control in control valve applications with complementary, exclusive, and progressive modes, practical examples, valve.
Exclusive Control Valve Sequence | Split-ranged Control Valves
0% = valve a wide open, valve b shut 25% = valve a 50% open, valve b shut 50% = valve a shut, valve b shut.
But which configuration suits your loop best—complementary, exclusive, or progressive?
Capacity is increased by progressive. Common modes of control valve sequencing seen in the process industry are:. Split range control some control loops have two control valves on the output signal of one controller For example with two control valves, one valve.
Pressure controls (other than relief and unloading valves) there are some parts of fluid power circuits that need pressure control
