Working principle and purpose of the product:

The electronic electric top guide regulating valve consists of a PS series or 3610 series linear electric actuator and a low flow resistance straight through single seat valve. (It can also be paired with other brands of direct travel actuators). The electric actuator is an electronic integrated structure with a servo amplifier inside. By inputting control signals (4-20mADC or 1-5VDC) and power supply, the valve opening can be controlled to adjust working parameters such as pressure, flow rate, liquid level, and temperature. It has the characteristics of sensitive action, simple connection, large flow rate, small volume, and high adjustment accuracy. The control accuracy and performance are significantly improved compared to the DKZ type.

Single seat valves are suitable for situations with strict requirements for leakage, low pressure difference before and after the valve, and a certain viscosity. Applied in industries such as power, metallurgy, chemical, petroleum, environmental protection, light industry, equipment, etc.

Product Structure Features:

1. The valve body is designed according to the principles of fluid mechanics, with a low flow resistance flow channel of equal cross-section, and the rated flow coefficient is increased by 30%.

2. The adjustable range is large, with an inherent adjustable ratio of 50, and the flow characteristics include straight lines and equal percentages.

3. The electric sleeve regulating valve plug is equipped with upper and lower pressure equalization holes, which have low unbalanced force, good valve stability, strong sleeve interchangeability, and large pressure difference during use.

4. The regulating cut-off type adopts a soft sealing structure valve core, which meets the VI level leakage standard (zero leakage).

5. The servo amplifier adopts deep dynamic negative feedback, which can improve the accuracy of automatic adjustment.

6. There are various forms of electric operators that can be applied to 4-20mA. DC or 0~10mA DC。

7. Electronic electric control valves can be directly controlled by current signals to regulate valve opening, without the need for servo amplifiers.

8. The bellows sealed regulating valve forms a complete seal on the moving valve stem, blocking fluid leakage
