How to choose electric metal seal butterfly valve

When choosing the electric metal seal butterfly valve, you must pay attention to the properties of each part. If you can't choose a better product, the effect of using it will have a bad effect. When choosing a butterfly valve product, the first thing to look at is the stem diameter. If it is a multi-swing stem valve, it cannot be assembled into a motorized valve during installation. Therefore, some maximum stem diameters cannot be used for the valve stem in this environment. The inner diameter of the hollow output shaft of the motorized device must be larger than the outer diameter of the stem of the open stem valve. For the operating torque of the product, this is the main parameter of the valve motorized device.

　　The effect of electric butterfly valve in its movement process is determined and controlled by the internal stroke, torque and axial thrust. In addition to the correct selection of electric metal-sealed butterfly valves, we should also choose the correct valve motorized device. In order to prevent the operating torque from being higher than the control torque, the correct valve motorized device is critical. Purchasers should know that the most appropriate range of output torque for motorized devices is 1.5 or 1.2 times the maximum working torque of the valve. In addition, for the working thrust of motorized butterfly valves, attention should be paid to the configuration of the thrust plate. If there is no thrust plate, the internal stem nut will be an important power component.
