Pneumatic control valve in the position in modern factory

In the automatic control of modern factory, pneumatic control valve plays a very important role, the production of the factory depends on the correct allocation and control flow of the medium. These controls both the exchange of energy, pressure reducing, or is a simple container loading, will need some final control elements to complete. The output of the transducer are sent to the adjusting instrument & ndash; — Regulator, it determines or expectations and the process parameters and to measure a given value deviation between the actual value, one by one, the correction signal is sent out to final control element & ndash; — Pneumatic control valve. In the field of industrial automation process control, by accepting conditioning control unit of the output control signal, from engine operation to change the medium flow rate, pressure, temperature, liquid level of the process parameters such as the final control element. And valve general, the executing agency. If the trip characteristics of pneumatic control valve can be divided into straight stroke and stroke; By their ticket enforcement agencies use the power, according to its functions and features are divided into linear features, such as percentage and parabolic characteristics of three. Pneumatic control valve applied to air, water, steam, all kinds of corrosive medium, mud, oil, etc.
