What are the Types of Test signals?

For many practical control processes, the input drives are unknown in advance, unlike electrical circuits and communication systems. In many cases, the actual inputs to a control system generally can vary randomly with respect to time. A designer faces a challenge since it is difficult to design a control process that works satisfactorily with any… Read More What are the Types of Test signals?

Types of wear to which a Control Valve is exposed

In the study of control valve failure analysis, it is necessary to have a detailed knowledge of the wear mechanisms since the detachment of material from a mechanical component can vary remarkably, from very intense to insignificant. It means a total loss of efficiency or complete utility of the item. The wear mechanisms that affect… Read More Types of wear to which a Control Valve is exposed

What is Rotameter? Principle, Classification, Advantages, and Disadvantages.

Description of Rotameter Rotameter is also called a variable area flowmeter. It is a type of flowmeter that measures flow rate or volumetric flow rate. It is defined as the amount of flow per unit of time that circulates through a section of a tube. The rotameter is a conical tube, usually made of glass,… Read More What is Rotameter? Principle, Classification, Advantages, and Disadvantages.

How does a Solenoid Valve work? Operating Principle, Types

We can define a solenoid valve as a device that has the purpose of controlling the flow of liquids or gases that is electrically actuated and can also be installed in remote or difficult-to-access places. The solenoid valves can be subjected to hostile working conditions. It can be controlled by simple electrical switches. It can… Read More How does a Solenoid Valve work? Operating Principle, Types

Directional Control Valves, Difference between Monostable and Bistable Valves

Directional control valves are those which change the flow of compressed air that goes to the cylinders, pneumatic valve actuators, etc., By switching, opening, or closing their internal connections, they control compressed air passage. It allows control of the inlet and outlet of a cylinder, the opening or closing of a pneumatic clamp, or the… Read More Directional Control Valves, Difference between Monostable and Bistable Valves
