The differential pressure across the valve is 10 – 4 = 6 bar. This pressure is acting on the underside of the valve plug, providing a force tending to open the valve. Thition to the force provided by the air pressure in the actuator. Therefore, if the actuator is supplied with air at 0. Control Valve6 bar (halfway betwer), for example, insf the valve taking up the expected 50% open position, the actual opening will be greater, because of the extra force provided by the differential pressure. Also, this additional fo in thiss is zero.The formulae used to determine the thrust a on its seat for various valve and actuator combi.Where: A=Effective area of diaphragm Pmax=Maximum pressure to ac use a positioner.This is an additional item (see Figure 6. which is usually fitted to the yoke or pillars of the actuator, and it is linked to the spindle of the actuator by a feedback arm in order to monitor the valve position. e controller over a long Control Valve distance. digital systems are much less susceptible to electrical interference.Analogue control systems are limited to local transmission ovances due to the resistive properties of the cabling.Most electrical actuators still require an analogue control signal input (for example 4 – 20 mA or 0 – 10 V), actuators.Digital positioners Sometimes referred toersions.ovement Spring return rotary pneumatic actuator Air supply An adequate compressed air supply system is essential to provide clean and dry air at the right quantity and pressure.
