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.
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.
