In 2012, Automation World published an article looking at the decision factors faced when choosing electric or pneumatic actuators. More than a decade later, manufacturing engineers and OEMs still ...

This article examines an urban gas network that experienced pressure fluctuations that manual regulators could not safely control. These issues were compounded by hazardous Zone 0 conditions that made ...

Pilot pressure can be understood as the pneumatic control signal that defines the setpoint of a regulator. This pilot signal is generated by a separate pilot device in pressure control systems that ...

The new Bendix AD-HFi air dryer features the same design as the AD-HF dryer, which was launched in 2019, but incorporates a solenoid-operated valve that replaces the traditional mechanical governor.

PID loops are a central component of modulating boiler control systems with applications ranging from basic steam header pressure control to cascading 3-element drum level control. A modern ...

Feedback-control schemes for linear systems have been around since at least the 17 th century, regulating pressure and distance between millstones and then, famously, to control James Watt’s steam ...
