Detailed analysis of the importance of the three characteristics of intelligent electric control valve

Intelligent electric control valve is a pressure balanced electric intelligent control valve. It is equipped with intelligent electric actuator, which accepts a unified 4-20mA or 1-5V · DC standard signal, converts the current signal into a corresponding linear displacement, and automatically controls the opening of the regulating valve to achieve the pressure of the fluid in the pipeline, Continuous adjustment of process parameters such as flow, temperature, and liquid level.

Pneumatic ventilation butterfly valve can be combined into different performance valves

Pneumatic ventilation butterfly valve is a special method of shut-off valve, appeared in the 1920 s. Its opening and closing parts are a piece of butterfly valve made of soft materials, the valve body cavity and the valve cover cavity and drive components separated, so called pneumatic ventilation butterfly valve. The outstanding feature of pneumatic ventilation butterfly valve is that the butterfly valve separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, so that the valve stem, valve clack and other parts located above the butterfly valve are not corroded by the medium, eliminating the need for packing and sealing structure and no medium leakage.

How to install pneumatic ultra-thin ball valve, how to check after installation?

Pneumatic ultra-thin ball valve can also be called wafer type pneumatic ball valve. It has the characteristics of compact structure, small size, light weight, and convenient installation. It is a new type of ultra-short flange pitch ball valve developed by absorbing Italian technology and domestic design. It is connected by a direct connection actuator and has the advantages of compact structure, small size, light weight, low friction resistance, small return difference, stable and reliable action. It can be widely used in petroleum, chemical industry, metallurgy, power station, light industry and other fields to automatically adjust or cut off oil, water, gas, pulp or fibrous fluid.

How to install, repair and do routine maintenance work for pneumatic control valve?

1, gas open type (normally closed type) is when the air pressure on the membrane head increases, the valve to increase the opening direction of action, when the upper limit of the input pressure is reached, the valve is in a fully open state. Conversely, when the air pressure decreases, the valve moves in the closing direction, and when there is no input air, the valve is fully closed. Gu usually we call the gas-open regulating valve a fail-closed valve. The choice of gas opening and closing is considered according to the safety point of view of process production. When the gas supply is cut off, the regulating valve is in the closed position or the open position is safe.
