Explain Split Range Control In Control Valve Briefly.

Answer Posted / nilesh karpe

In addition wt ANS.1-
in split range control the control signal is split in two
ranges according to the application .for eg,4-20MA.signal
can be used as 4-12 MA. FOR VALVE A OPEN i.e.50%.& 12-20MA
for vlv b open.vice-versa.
