8T710B35SA is an electric-driven valve positioner used in the field of industrial automation. Its main function is to convert the input signal of a remote control device into a mechanical displacement, so that the valve is driven to the required opening position. This positioner is suitable for use in high flow and low pressure industrial control systems, such as sewage treatment, steel smelting, and the manufacture of paper products.

The working principle of the 8T710B35SA positioner is relatively simple. It consists of a pneumatic control cylinder, a piston, a spring member, a housing, and a diaphragm assembly. The housing is connected to the valve stem. When an electric signal is sent to the positioner, the piston is powered to move the diaphragm, which in turn, pushes the air in the cylinder. This effect pushes the spring and the housing, thus driving the valve stem to move according to the signal. The more electric signals, the more force that is applied to the stem, which will employ quicker acceleration and greater displacement.

The 8T710B35SA positioner also has several advantages. It is able to detect the actual opening degree of the valve, and the built-in feedback control system can automatically adjust the opening degree. This is helpful for ensuring the accuracy and stability of the valve position. Furthermore, the piston of the positioner is made of wear-resistant material, so that it can reduce the internal friction and improve the valve’s lifetime. Finally, its advanced design reduces vibration noise and increases its operation reliability.

In conclusion, the 8T710B35SA positioner is suitable for use in high flow and low pressure industrial control systems. Its working principle is relatively simple and it has several advantages, such as its feedback control system, wear-resistant piston, and noise reduction. Thus, the 8T710B35SA has become an essential tool for industrial automation.
