This basic control theory tutorial looks at on/off and continuous control modes. It introduces proportional, integral and derivative control actions and explains some of the terminology. Courtesy of Spirax Sarco and MSEC. Topics Include: On/off control Continuous...
Understanding industrial control valve design and operation is very important if you work as a process engineer, a plant maintenance person, or if you design process control loops. Control valves are used extensively in power plants, pulp and paper mills, chemical...
The manufacturers of valves and other fluid control components for the processing industries have never been shy about tweaking designs to deliver better performance for a particular set of operating conditions. The available basic valve designs, along with their...
Spirax-Sarco is a globally recognized manufacturer of valves, traps, and a host of other steam system specialties. Their Spira-Trol line of globe valves can be employed throughout steam of other process fluid systems to provide accurate flow regulation. The valves are...
A solenoid is an electric output device that converts electrical energy input to a linear mechanical force. At the basic level, a solenoid is an electromagnetic coil and a metallic rod or arm. Electrical current flow through the coil produces a magnetic field, the...
Fluid processes will employ control valves to regulate flow or pressure in between the extremes of fully open and fully closed. Their function and design are specifically different from shutoff valves, which are designed and intended for the isolation of segments of a...
