What is the most suitable valve for flow control? A diaphragm valve is ideal for flow control, as the aperture control is linear. If the valve is half closed, the flow will be reduced to half. Can this type of diaphragm valve be installed in an automatic control application? Yes, a diaphragm valve can be installed in automatic control applications by using a pneumatic actuator with a 3 to 15psi flow. Using a Programmable Logic Controller (PLC) also allows the flow to be controlled.
