      Three Different Types of Control Valves and Their Characteristics

      • Клапан DELCO

      Control valves realize precise control of the system by adjusting the parameters such as flow, pressure and temperature of the fluid. According to different driving methods and working principles, control valves are mainly divided into electric control valves, self-operated control valves and pneumatic control valves. Below, Клапан DELCO will introduce these three types of control valves and their characteristics.

      Electric Control Valve

      Electric control valves are mainly composed of electric actuators and control valves. It is powered by electricity, through the receipt of the controller’s signal, drive the valve switch changes, so as to regulate the area of the fluid path, to change the fluid flow, pressure and temperature and other parameters of the purpose. Electric control valve is widely used in petrochemical, electric power, metallurgy and other industries, especially suitable for the need for high-precision control occasions. Electric control valve has the following advantages:

      • Precise control: due to the high precision of the electric actuator, precise adjustment of fluid parameters can be realized.
      • Easy to realize automation: it can be seamlessly connected with various control systems to realize remote control and automated operation.
      • High stability: electric control valve in the operation process, by the external interference is small, stable operation.

      Пневматический регулирующий клапан

      Pneumatic control valve is powered by compressed air, through the controller’s signal to adjust the area of the fluid path to change the fluid flow valve. Pneumatic control valve usually adopts pneumatic membrane actuator, so it is also known as pneumatic membrane control valve. Pneumatic control valves are widely used in chemical, pharmaceutical, food processing and other industries, especially suitable for explosion-proof requirements of high working environment. Compared with electric control valves, pneumatic control valves have the following advantages:

      • No need for explosion-proof measures: Since the pneumatic control valve is powered by compressed air, it avoids the safety hazards of electrical equipment in explosive environments.
      • Fast response: pneumatic actuator response is sensitive, can quickly adjust the valve switch state, suitable for rapid response to the high demand for occasions.
      • Simple operation: the structure of the pneumatic control valve is relatively simple, easy to install and maintain.

      Self-operated Control Valve

      Self-operated control valve, is a type of control valve that does not require additional energy. It directly uses the energy of the regulated medium to manipulate the regulating mechanism to achieve automatic control. Self-acting control valves are suitable for a variety of occasions that require stable control, such as temperature control in the HVAC system, pressure adjustment in the water treatment system. The main features of self-operated control valves are as follows:

      • No need for external energy: self-operated control valves are driven by the energy of the medium itself, which reduces energy consumption and operating costs.
      • Simple structure: the structure of self-operated control valve is relatively simple, easy to maintain and operate.
      • High reliability: Because it does not rely on external energy, it can still work normally in the case of unstable or lack of energy supply, and has high reliability.
