备注：R 气开式D 气闭式                                                                                    Remarks; R for air to opne D for air to close

H栏尺寸不包含手轮、定位器、加大执行器尺寸                                                       he dimension of H does not contain a hand wheel,positioner,enlarged acutor

  此阀设有一个改善套筒周围流体平衡流动的导流翼，是控制高压流体的阀门，是一种压力平衡式调节阀。有压降小，流量大，可调范围广，流量特性精度高的特点。执行器可采用气动薄膜式、电子式电动执行机构，出厂时已经将零点程调试完毕，用户接通气源输入信号即可运转使用。

1.接线简单，操作简易。

2.调节性能优异，流量系数精确。

3.通道呈S型号，压力损失小，流通能力强。

4.有一定黏度和少量纤维的介质也可以选用。

The valve has a trning vane improving the sleeve surrounding fluid flow balance, and is a high pressure fluid control valve, and is a kind of pressure balance type regulator. It has the characteristics of small pressure drop,large flow, wide adjustable range, and flow characteristic of high precision. Actuator can adopt pneumatic diaphragm and 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 coeffcient 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.

备注

1. 最大允许压差不超过最大工力。

2. 同一格内，’’/’’前方数字表示阀常开允许压差，后方数字表示阀全关允许压差。

3. 以上允许压差均采用标准执行机构，当压差不满足时，也可增大执行机构。

Note

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 actuator.
