YES, ABSOLUTELYU. WE CAN USE CONTROL VALVE W/O POSSITIONER.
BASICALLY POSSITIONER IS USED FOR QUICK OPERATION OF
CONTROL VALVE. FOR AN EXAMPLE: IF CONTROL VALVE OPERATING
RANGE IS 0.6 TO 2.6 KG/CM2, AT THAT TIME POSSIOTIONER IS
USED FOR AMPLIFICATION FOR THE HIGH PRESSURE CONTROL VALVE
EVEN IF INPUT PRESSURE IS 0.2 TO 1.0 KG/CM2.
