Lino PR11 high pressure adjustable air gas reducing regulating regulator valve is an essential accessory of the pneumatic control valve. Its main function is to reduce the pressure of the air source and stabilize it to a certain value, so that the control valve can obtain stable air source power for adjustment and control. In the laboratory, gases such as oxygen, nitrogen, hydrogen, and chlorine are often used. These gases are generally stored in special high-pressure gas cylinders. When in use, the gas pressure is reduced to the range required by the experiment through the pressure reducing valve, and then finely adjusted by other control valves to input the gas into the use system.
