Stainlesar.With a larger valve and / or a higher differential pressure to work against, moreg range isControl Valve needed. This is why controls manufacturers offer a range of pneumatic actuators to match a range of valves – comprising increasing diaphragm areas,The diagrams in Figure 6.3 show the coial pressures. A higher control pressure and stronger springs could beControl Valve used,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. It requires its own higher-pressure air supply, which it uses to position the valve. and will provide any output pressure to the actuator to satisfy this relationship, according to the requirements oents.
