Electric Control Valve

product-460-553

Working Principle Diagram

Electric single-seat control valve is one of the most widely used valve types. It is mainly composed of an electric actuator and a straight-through single-seat control valve. There is a valve core and a valve seat in the valve body. The valve core has a plunger-type structure and has It has the characteristics of small leakage. According to the signal from the adjustment part, the opening of the valve is automatically controlled to achieve the adjustment of medium flow, pressure and liquid level. The equal percentage characteristics are optimal, with stable adjustment and good adjustment performance.

Since the electric single-seat control valve has only one valve core, it is easy to ensure sealing. The unbalanced thrust caused by the pressure difference on the valve core is large. It is suitable for clean media applications with strict leakage requirements and small pressure difference. It is widely used for precise control of gases, Liquid, steam and other media.

Working Principle

The electric single-seat control valve has an electronic integrated structure and contains a feeding function. It accepts analog signals (4-20mA or 1-5V·DC) from the current or voltage of the control system, and converts the current signals into corresponding linear displacements. , automatically controls the opening of the valve to achieve continuous adjustment of pressure, flow, liquid level, temperature and other process parameters, so as to maintain the controlled process parameters at a given value and achieve remote automatic control. The adjustable range is large, the inherent adjustable ratio is 50, and the flow characteristics include straight line and equal percentage.
