Introduction to OKE Electric Control Valves

Electric control valves are essential industrial automation process control execution unit instruments. They operate by receiving signals (e.g., 4~20mA) from industrial automation control systems to drive the valve, altering the cross-sectional area between the valve core and seat. This controls process parameters such as flow rate, temperature, and pressure of the pipeline medium, enabling automated regulation.

Applications of OKE Electric Control Valves

Electric control valves are widely used in various industrial production sectors, including power, chemical, metallurgy, environmental protection, water treatment, light industry, building materials, and other industrial automation systems. In water systems, electric control valves serve as key auxiliary equipment for regulating boiler feedwater flow. They can accept 4-20mA DC current signals from automatic control systems to adjust the valve opening, thereby changing the flow rate of the controlled medium.

Features of OKE Electric Control Valves

Compared to traditional pneumatic control valves, electric control valves offer the following advantages: energy efficiency (consuming electricity only during operation), environmental friendliness (no carbon emissions), and quick, convenient installation (no complex pneumatic pipelines or air pump stations required). Additionally, electric control valves feature self-diagnostic capabilities; in the event of a malfunction, indicator lights on the controller immediately signal an alert.

How to Choose an Electric Control Valve

When selecting an electric control valve, the flow characteristic can be chosen based on the requirements of the application. Electric control valves have three types of flow characteristics: linear, equal percentage, and parabolic. The equal percentage characteristic offers the advantage of small flow changes at low flow rates and large changes at high flow rates. The parabolic characteristic provides better regulation performance than the linear characteristic.

In summary, electric control valves are efficient and reliable control devices suitable for a variety of industrial production and process control scenarios.
