Intelligent Electric Control Valve Explosion Proof Linear / Rotary Electric Flow Control Valve

Electric control valve is an automated valve that achieves precise flow regulation by receiving control signals through an electric actuator.

• No need for complex air supply systems: It can operate simply by connecting power and control signal lines, eliminating the need for large auxiliary equipment such as air compressors, air tanks, and dryers, thus reducing initial investment and installation complexity.
• High precision and control performance: Advanced digital control technology ensures extremely high positioning accuracy, small dead zone, sensitive response, and superior control quality.
• Strong anti-deviation capability: Fluctuations in power supply voltage have little effect on its output torque.
• Suitable for long-distance signal transmission: Electrical signals can be transmitted over long distances without loss, regardless of distance.
• Environmentally friendly and energy-saving: No gas leakage issues and low operating noise.
• Highly integrated functions: One device integrates execution, positioning, and control functions.

• Power Supply Specifications: Commonly AC380V, AC220V, DC24V, etc.
• Control Signal: 4-20mA DC.
• Flow Characteristics: Equal percentage, linear or quick opening.
• Valve Body Type and Size: Select based on process medium, pressure, temperature and calculated Kv value.
• Thrust/Torque: Ensure the actuator's output force/torque can overcome the valve's unbalanced force or friction.
• Protection and Explosion-proof Grades: Choose according to the installation environment. At least IP67 for outdoor use. Explosion-proof certification (such as Ex d IIB T4 Gb) is required in flammable and explosive areas.

• Electric control valves are suitable for situations where there is a lack of air supply or where high control accuracy is required.
• Power industry: Boiler feed water and desuperheating water regulation.
• Fine chemicals and pharmaceuticals: Processes requiring precise batching and flow control.
• Building automation: Precise regulation of hot and cold water in central air conditioning systems, energy-saving control.
• Water treatment and environmental protection: Precise dosage control in dosing systems.
• Food and beverage: Flow regulation in batching and mixing processes.
• Small boilers and heating stations: In situations without air compressors.

• Prioritize electric: No air source available, control points are extremely scattered and distant, extremely high control accuracy is required, and the environment is not flammable or explosive.
• Prioritize pneumatic: There is an existing air source, the environment is flammable or explosive, ultra-fast response is required, and on-site maintenance capability is weak.

Electric control valves are the "electricity-controlled flow" precision artists. Through highly integrated electronic control systems, they transform complex control tasks into precise mechanical actions. Although their individual cost and maintenance threshold are relatively high, in applications without a gas source, requiring high precision and long-distance control, they offer an extremely simple, efficient and reliable solution. With the development of electronic technology and digital bus technology, electric control valves are constantly evolving towards being more intelligent, more precise, and easier to diagnose and maintain, becoming an indispensable key device in modern automated factories.
