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...

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

Basics of Butterfly valves

The butterfly valve is a rotary control valve. Standard butterfly valves are dampers that are shaped from discs which rotate in the flow path to regulate the rate of flow. Working and Construction: Butterfly valves are quite simple to understand: the “butterfly” element is a disk that rotates per... Read More

Valve stem packing replacement method

VALVE STEM PACKING The purpose of valve packing is to prevent leakage.  In a typical valve, the gland follower is tightened until there is no leakage.  The valve is then test-operated to make sure that the packing is not compressed so tightly that the valve does not turn easily. Types of Packing ... Read More

Control Valve – How it works ? Components of Control Valve

Control Valve Basics A control valve is simply a variable orifice that is used to regulate the flow of a process fluid according to the requirement of the process. They can throttle flow over a range of fully open to fully closed. The control valve is normally used with an electric,pneumatic or h... Read More
