Pneumatic pneumatic control valve is closely related to our life

Pneumatic pneumatic - valve pneumatic pneumatic control valve is closely related to our life at first said, if not professionals may understand that it is a what things, what plays a role. But if I say it related industry, we may not be a stranger. Pneumatic pneumatic control valve is petroleum, chemical, electric power, metallurgy and other industrial enterprises one of the widely used industrial process control instrument. Usually are connected by a pneumatic actuators and pneumatic control valve installation and debugging after the formation of the combination instrument. It can be seen that the pneumatic pneumatic control valve is not an unfamiliar and distant vocabulary, it is closely related to our life, with the existence of the pneumatic pneumatic control valve, we all aspects of life to go smoothly. And because pneumatic pneumatic regulator's role is so important, for its quality requirements must also strive for perfection. The choice of the form of the choice of pneumatic - valve structure: steam flow control should choose single seat; Large diameter, large flow, low pressure difference occasions should choose butterfly valve, but at the moment, leakage is larger; When the medium to high pressure, should choose high pressure pneumatic control valve; To facilitate drainage, prevent the valve plug, optional Angle of pneumatic control valve; Heat exchanger of the water or water temperature regulation optional tee pneumatic control valve. Pneumatic control valve caliber choice: using on-off pneumatic control valve, can choose the valve diameter pipe diameter according to receive directly; Other situations should be according to the maximum flow of medium and valve pressure drop calculation of flow capacity Kv value to determine the diameter of the valve.
