The electric control valve is a hydraulically operated valve with a solenoid valve as a guide valve. It is often used for automatic control in water supply and drainage and industrial systems. The control response is accurate and fast, and the pipeline system is remotely opened and closed according to electrical signals to realize remote operation. Can replace gate valve and butterfly valve for large electric operati

A pneumatic valve is a valve driven by compressed air. When purchasing pneumatic valves, it is only necessary to specify the specifications, types, and working pressures to meet the purchasing requirements. flow. The difference between the pneumatic valve and the solenoid valve is the difference in the signal source. The solenoid valve uses electricity to control the pilot gas to push the valve core to change dire

The control valve has the characteristics of simple structure and reliable action, but because it is in direct contact with the process medium, its performance directly affects the quality of the system and environmental pollution, so the control valve must be regularly maintained and repaired, especially for harsh and important operating conditions. On occasion, more attention should be paid to maintenance work. Key

1. Small flow resistance. The medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small. 2. It is more labor-saving when opening and closing. Compared with the globe valve, because whether it is open or closed, the direction of movement of the gate is perpendicular to the flow direction of the medium. 3. The height is large and the opening and closing ti

1. The solenoid valve has excellent anti-leakage performance, opens and closes quickly, and has low power. It is suitable for use as a cut-off in some chemical pipelines such as corrosion and toxicity; electric valves are mostly used for pipeline flow regulation, and are normally installed in air supply and refrigeration. The air outlet of the pipeline can also be used in liquid pipelines, and is widely used in canne

Electric gate valve is a widely used valve, which is mainly used in the analog regulation of medium flow in liquid, gas and wind systems, and is AI control. In the control of large valves and wind systems, electric valves can also be used for two-position switch control. The operating principle of the electric gate valve is that the electric gate valve is usually connected by an electric actuator and the valve, an
