How to choose control pneumatic valve < / div >

pneumatic valve control role in the process control is to accept the regulator control signal, or computer change modulated medium flow, make the modulated maintain within the scope of the required parameters, so as to achieve the automation of production process. If the automatic control system compared with manual adjustment process, detection unit are the eyes of the people, to adjust the control unit is the brain of a person, then execute unit - Pneumatic control valve is the man's hands and feet. One in order to realize the process parameters such as temperature, pressure, flow, liquid level, such as adjusting control, cannot leave the control of pneumatic valve. So the correct selection of pneumatic control valve is of great significance in the process automation.
control pneumatic valve is also called pneumatic valve, is the main type of actuator, by accepting conditioning control unit of the output control signal, from engine operation to change fluid flow. Pneumatic control valve generally consists of actuators and pneumatic valves. If by their ticket enforcement agencies use the power, pneumatic control valve can be divided into pneumatic, electrical, fluid movement three, namely to compressed air to power sources pneumatic valve, pneumatic control for electric power source of pneumatic valves, electric control as a liquid medium ( Such as oil, etc. ) Pneumatic pressure as the power of electric hydraulic control valve, in addition, according to its function and feature points, and electromagnetic pneumatic valves, electronic style, smart, floor main line control pneumatic valve, etc. Pneumatic control valve product type many, the structure is also varied, but also in constant updates and changes. In general pneumatic valve is common, can match with pneumatic operation organ, also can match with electric actuators or other actuators.
WL - production 20000 series pneumatic control valve as the introduction of Italy advanced design and manufacturing technology, including a series of top oriented straight travel control pneumatic valve, to adapt to the working condition of a variety of requirements and design. Using the top oriented is not balanced in structure, high strength, heavy load fast disassembly type cage pressure pneumatic spherical pneumatic valve core seat, curve, suitable for all kinds of different pressure and temperature of fluid or gas control, closed tightly; The sealing performance of soft seal has no leakage.
as the world's important suppliers of pneumatic valve control, absorb the innovation in the field of pneumatic control valve, committed to the development and production of high quality pneumatic control valve, and provide customers with a full range of industrial pipeline control scheme, the products are widely used in petroleum, chemical industry, electric power, metallurgy, food, medicine, urban construction, form a complete set of machinery and other industries.
