Note: The differential pressure of throttle in the flow valve includes two types such as 0.02MPa and 0.05MPa, which shall be selected according to the actual situations. The differentia l pressure before and after the valve shall be higher than that of the throttle.

Working principle

After the controlled medium enters the valve, the before-valve pressure P1 is input into the lower diaphragm chamber through the control pipeline, and the pressure Ps after throttling by the throttle valve is input into the upper diaphragm mchamber. The difference between P1 and Ps â–³Ps=P1-Ps is called effective pressure. The difference between the thrust producedon the diaphragm by P1 and the thrust produced on the diaphragm by Ps determines relative positions of the plug and seat and determines the flow that passes through the valve. When the flow that passes through the valve increases, i.e. â–³Ps increases, P1 and Ps respectively acts on the lower diaphragm chamber and upper diaphragm chamber to make the plug move towards the seat,

so that the flow area between the plug and seat is changed and Ps is increased . The thrustacted on the diaphragm by the increased Ps, the reacting force of the spring and the thrust acted on the diaphragm by P1reaches balance at the new position to realize the purpose of controlling f low, and vice versa. The flow of the controlled medium is determined through adjusting relative positions of the throttle valve and seat.     

Calibration chart: To set the flow more accurately and quickly, the following calibration charts are offered for you reference (please measure the flow with a flow meter if you need to set the flow more precisely or set the flow

for valves with DN150-250).

The calibration chart is only applicable to water, and serves as a reference for other media, whose flow shall be properly adjusted in the actual process..

Working principle

when the temperature of the controlled object is higher than the set temperature ,the liquid in the temperature controller will swell ,the force on the push of the actuator increases ,and the pulg makes the valve open under the action of the temperature controller ,the flow of water ,

or other cooling media is enhanced ,so that the temperature of the controlled object decreases ,the valve will be closed when the temperature of the controlled object decrease to the set value.after the valve is closed ,the temperature of the controlled object decreases  and the valve is opened again .the cooling media enter the heat exchanger and the temperature decreased again ,so as to make the temperature of the controlled object be a constant.the opening of the valve is related to the difference between the actual temperature of the controlled object and the set temperature.

Difference between actuator T06 and T17

The T06 model temperature sensor is isolated from the controlled medium through the temperature sensor sleeve, i.e., it does not contact the medium and it is easy to maintain. But the response is slow. It is suitable for controlling liquid media. The T17 model temperature sensor directly contacts the controlled medium, and the temperature sensing area is large. Therefore the response is fast. But it is not easy to maintain. It is suitable for controlling gas temperature and liquid temperature.

Working principle

When the temperature of the controlled object is lower than the set temperature, the liquid in the temperature sensor will contract, the force acted on the push rod of the actuator decreases, and the plug makes the valve open under the action of the spring force. The flow of steam, hot oil and other heating media is enhanced, so that the temperature of the controlled object rises. The valve will be closed when the temperature of the controlled object rises to the set value. After the valve is closed, the temperature of the controlled object falls and the valve is opened again. The heating media enter the heat exchanger and the temperature rises again, so as to make the temperature of the controlled object be a constant. The opening of the valve is related to the difference between the actual temperature of the controlled object and the set temperature.

Working principle

After throttling by the plug and seat, the before-valve pressure P1 of the process medium is changed into the after-valve pressure P2. Through the control pipeline, P1 is input to the upper diaphragm chamber of the actuator and acts on the top disc. The acting force produced balances the reacting force of the spring, determining relative positions of the plug and seat and controlling the before-valve pressure. W hen the before-valve pressure P1 increases, the acting force of P1 that acts on the top disc will increase accordingly. At the time, the acting force on the top disc is higher than the reacting force of the spring to make the plug move away from the seat, until the acting force on the top disc balances the reacting force of the spring. At the time, the flow area between the plug and seat is increased, the flow resistance becomes lower and P1 is reduced to the set value. Likewise, when the before-valve pressure P1 decreases, the acting direction is reverse to the above. This is the working principle during the control of before-valve pressure. When it is necessary to change the set value of before-valve pressure P1, please adjust the adjusting nut.

Working principle

After throttling by the plug and seat, the before-valve pressure P1 of the process medium is changed into the after-valve pressure P2. Through the control pipeline, P1 is input to the upper diaphragm chamber of the actuator and acts on the top disc.

The acting force produced balances the reacting force of the spring, determining relative positions of the plug and seat and controlling the before-valve pressure. W hen the before-valve pressure P1 increases, the acting force of P1 that acts on the top disc will increase accordingly.

At the time, the acting force on the top disc is higher than the reacting force of the spring to make the plug move away from the seat, until the acting force on the top disc balances the reacting force of the spring. At the time, the flow area between the plug and seat is increased, the flow resistance becomes lower and P1 is reduced to the set value. Likewise, when the before-valve pressure P1 decreases, the acting direction is reverse to the above. This is the working principle during the control of before-valve pressure.

When it is necessary to change the set value of before-valve pressure P1, please adjust the adjusting nut.

Working principle

After throttling by the plug and seat, the before-valve pressure P1 of the process medium is changed into the after-valve pressure P2. Through the control pipeline, P1 is input to the upper diaphragm chamber of the actuator and acts on the top disc.

The acting force produced balances the reacting force of the spring, determining relative positions of the plug and seat and controlling the before-valve pressure. W hen the before-valve pressure P1 increases, the acting force of P1 that acts on the top disc will increase accordingly.

At the time, the acting force on the top disc is higher than the reacting force of the spring to make the plug move away from the seat, until the acting force on the top disc balances the reacting force of the spring. At the time, the flow area between the plug and seat is increased, the flow resistance becomes lower and P1 is reduced to the set value. Likewise, when the before-valve pressure P1 decreases, the acting direction is reverse to the above. This is the working principle during the control of before-valve pressure.

When it is necessary to change the set value of before-valve pressure P1, please adjust the adjusting nut.

Working principle

After throttling by the plug and seat, the before-valve pressure P1 of the process medium is changed into the after-valve pressure P2. Through the control pipeline, P1 is input to the upper diaphragm chamber of the actuator and acts on the top disc.

The acting force produced balances the reacting force of the spring, determining relative positions of the plug and seat and controlling the before-valve pressure. W hen the before-valve pressure P1 increases, the acting force of P1 that acts on the top disc will increase accordingly.

At the time, the acting force on the top disc is higher than the reacting force of the spring to make the plug move away from the seat, until the acting force on the top disc balances the reacting force of the spring. At the time, the flow area between the plug and seat is increased, the flow resistance becomes lower and P1 is reduced to the set value. Likewise, when the before-valve pressure P1 decreases, the acting direction is reverse to the above. This is the working principle during the control of before-valve pressure.

When it is necessary to change the set value of before-valve pressure P1, please adjust the adjusting nut.
