Use and characteristics of pneumatic control valve

Pneumatic dispatching valve is one of the industrial process control instruments widely used in petroleum, chemical, electric power, metallurgy and other industrial enterprises. According to the operation principle of pneumatic dispatching valve, compressed air is used as the power source, air cylinder is used as the performance arrangement, electric valve positioner, converter, solenoid valve, positioning valve and other accessories are used to drive the valve, end the switching value or share dispatching, receive the control signal of industrial automatic control system, and end the dispatching of pipeline medium: flow, pressure, temperature and other process parameters. Pneumatic dispatching valve is characterized by simple control, fast response, intrinsically safe, no need to take explosion-proof method.

How to use the electric valve can extend the life

Daily electric valve maintenance 1. The electric valve should be stored in a dry and ventilated room, and both ends of the passage should be blocked. 2. Electric valves stored for a long time should be checked regularly to remove dirt and apply anti-rust oil on the processing surface.

Stable performance of the pneumatic valve how to choose

Pneumatic valve is a common fluid control equipment in industrial pipelines. It is mainly composed of pneumatic actuators and valves. The valves are driven by tightening clean air to control the circulation and shutdown of pipeline media, and the performance speed is very fast. It is generally used to quickly cut off the application. Pneumatic valves are generally equipped with a variety of accessories, such as solenoid valves, air treatment trio, limit switches, positioners, control boxes, etc. To achieve local control and remote collection control. Assume that for demand-only on and off.

Pneumatic control valve in the maintenance of what steps

Clean the outer surface of the valve, and clean it with compressed air or fuel oil. Check and record the valve nameplate, other signs, important information, etc. Be careful to disassemble the various parts of the valve in order. Use kerosene when cleaning parts.

What is the function of intelligent electric control valve

The intelligent electric control valve uses the energy of the medium itself to be adjusted to directly schedule and control the temperature of the medium such as steam, hot water, hot oil and gas, and can also be used to prevent overheating or heat exchange places. The valve has simple structure, convenient operation, wide temperature adjustment range, fast response time, good sealing performance, and can stop scheduling at will during operation, therefore, it is widely used in hot water supply in chemical, petroleum, food, textile, hotels and restaurants.
