Overview and principles of various valves, you will understand after reading (2)
1. Regulating valve Regulating valve, also known as control valve, is a final control component in the field of industrial automation process control that changes process parameters such as medium flow rate, pressure, temperature, and liquid level through power operation by receiving control signals output from the regulating control unit. It is generally composed of an actuator and a valve. If according to the characteristics of the stroke, the regulating valve can be divided into straight stroke and angular stroke; According to the power used by the actuator, it can be divided into three types: pneumatic control valve, electric control valve, and hydraulic control valve; According to its function and characteristics, it can be divided into three types: linear characteristics, equal percentage characteristics, and parabolic characteristics. Regulating valves are suitable for media such as air, water, steam, various corrosive media, mud, oil, etc. English name: control val...
