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
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.
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.
