Answer Posted / ajith294

here more answers reagrading positioner

maximum of the answers are 'YES' especially Answer number
10,
then i have a doubt that how control a valve at 50% open,
with out a positioner.

if there is not a positioner, how we can control the valve
( control the pnumatic pressure is applied the
actuator)?????

if a valve it using fully open of fully close condtion
throgh Solenoid Valve ( bypass the air to actuator) is on
off valve.

Without a positioner we cannot control the valve through a
controller.
