Since the pressure regulating pneumatic valve and control valve (3) the difference between

between the difference between the two types of products, the main control pneumatic valve is the only require additional energy ( Such as electricity or gas) Can drive, but the external control instrument signal need to change the relative position of pneumatic valve closing member also in order to realize the change in fluid flow. Self control pressure pneumatic valve is no external energy, without external control signal to adjust the instrument by the signal pressure media only, pressure regulator can be realized. Since the pressure of self adjust the characteristics of pneumatic valve, without external drive energy regulating pneumatic valve, thus reducing the power products, it has the following characteristics. Without external energy self-sufficiency pressure regulating pneumatic valve, work without electricity and gas occasions, convenient and save energy. , fine and mutual cross section pressure range, high precision of adjustment. The pressure setting can be set up in the process of continuous operation. , pressure regulating pneumatic valve, pneumatic valve and the ratio between the two is: before? : pressure pneumatic valve, rubber diaphragm detection, high accuracy, driver, motion.
