主要特點及用途

       單座調節閥的閥芯采用上導向結構,通道呈S型,有壓降小,流量大,可調范圍廣,流量特性精度高的特點,執行器可采用氣動薄膜式、電子式電動執行機構,出廠時已經將零點量程調試完畢,用戶接通氣源輸入信號即可運轉使用。

 

1.接線簡單,操作簡易。

2.調節性能優異,流量系數精確。

3.通道呈S型號,壓力損失小,流通能力強。

4.有一定黏度和少量纖維的介質也可以選用

 

valve core of single seat control valve adopts up guide structure,and the channel is Stype. It has the characteristics of small pressure drop,large flow,wide adjustable range,and flow characteristics of high precision.Actuator can adopt pneumatic diaphragm and electronic electeic actuator.When delivery,zero range has pneumatic diaphragm and electronic electric actuator. When delivery,zero range has been debugged. After the user switches on air input signal,it can operated and be used.

 

1.Wiring is simple,easy to operate.

2.Regulation performance is excellent, flow coefficient is accurate.

3.The channel is S type. Pressure loss is low,circulation ability is strong.

4.It can be applied to medium with viscosity and a small amount of fiber.

技術參數

備注

1.最大允許壓差不超過最大工力。

2.同一格內,‘’/‘’前方數字表示閥常開允許誤差,后方數字表示閥全關允許壓差。

3.以上允許壓差均采用標準執行機構,當壓差不滿足時,也可增大執行機構。

 Note

1. 1.The maximum allowable differntial pressure does not exceed the maximum pressure.

2.The number in the front of 7' indicates the allowable differntial pressure for valve  totally opened, the rear numerals indicates the allowable

   differntial pressure for valve totally closed.

3.The above allowable differntial pressure under standard actuator, If the differntial  pressure is not enough then can use enlarged 3. actuator.
