Pneumatic diaphragm valves use a pneumatic actuator to control the opening and closing of the valve diaphragm. They can be optionally equipped with intelligent controllers such as the C-TOP, positioners like the IL-TOP, and position feedback devices such as the F-TOP, thereby meeting a wide range of automated control requirements.
