Self-reliance type pneumatic control valve product model have?

Self-reliance type pneumatic control valve product model have? Self-reliance type pneumatic control valve is also called self-reliance type control valve. It has many advantages, such as a variety of models meeting the needs of many industries, etc. More and more industry needs the product, because its and with the development of science and technology, the performance of the products are improved greatly. Nowadays, more and more get the welcome of people, the following is the introduction of the related knowledge of products. Self-reliance type pneumatic - valve indirect effect indirectly type pneumatic control valve, added a command ( Pilot valve) It play a role of feedback signal amplification and then through the actuator, drive the main valve disc movement to achieve the purpose of the change of valve opening. If be pneumatic pressure regulator, feedback signal is the valve outlet pressure, by introducing actuator signal pipe. If the flow pneumatic control valve, the valve outlet has an orifice ( Or other resistance devices) Introduced by orifice plate ends out differential pressure signal actuators. If the temperature of pneumatic control valve, valve of the export is the temperature sensor ( Temperature or package) Through the temperature sensor in medium heat bilges cold shrink drive actuators. Warm prompt: today, the development of science and technology, self-reliance type pneumatic control valve products meet people's needs more and more, but now the technological level of manufacturing products manufacturer not neat, the price is different also, so can't free to choose products according to the price, otherwise can't guarantee the quality of the product, and also no guarantee after-sales.
