What is a butterfly valve and what is it used for
Butterfly valves are valves that can be used for regulating, isolating, stopping, or starting the fluid flow. These valves are mostly used as control valves in applications where the pressure drops required of the valves are relatively low. These valves can be used as either shutoff valves or as ...Read more -
What is a limit switch and how does it work?
A limit switch is a low power switch which, is a snap-action device and it would open or close its contact according to the position of the mechanical part. This switch would operate when there is a motion of the machine parts or it would also operate during the presence of an object. So we can d...Read more -
Comparison between PLC, DCS, and SCADA
What is a PLC control system and how does it operate? The Programmable logic controller is a digitally operated device that has a programmable memory for storing the instructions and also to do, the specified functions. A PLC would do logic, arithmetic, timing, counting, and sequencing functions ...Read more -
Features of Plug valve
Plug valve is a rotary control valve which is used to control flow. Plug valves are simple and often economical. The plug valve is much similar to the globe valve. Construction and working: The simplest form of a plug valve is the petcock. The body of a plug valve is machined to receive the taper...Read more -

How a Valve is controlled using a 4-20mA loop
Valve positioners are used to control the valve actuator position of the control valve. The positioner receives the signal from the controller and correct position by increasing or decreasing the air load pressure on the actuator. Signal conversion: A 3 to 15 PSIG pneumatic signal would be sent f...Read more -
How to do the control valve maintenance?
There are many types of control valves and these valves are used for many industrial purposes. In a piping system, the control valves are inevitable and this valve can be used to start or stop the flow in a pipeline, it can also adjust the amount of flow. So in a piping system, the valve should w...Read more -
What is a control valve positioner and how does it work
What is a control valve positioner and can we use a control valve without positioner Positioners are devices that help the control valve for positioning its actuator with the help of a control signal. Positioners would act according to the input signal it receives and this device would receive th...Read more -
Calibration of control valve positioner
Introduction Positioner is a device put into a valve to ensure that it is at correct position.An open/close operation of control valve also can be done with an I/P converter but the position of the valve can’t be confirmed. calibration of control valve positioner is crucial calibration that shoul...Read more -
What is the Three-way Control Valve
The three-way control valve is widely used to control the process parameters of gases, liquids, steam, and other media. Such as pressure, flow, temperature, levels, and other parameters are maintained at a given value. The three-way control valve is suitable for dividing a fluid into two outflows...Read more
