Pneumatic element is the element that works through the force generated by the pressure or swelling of the gas , it means the elastic energy of compressed air converted into dynamic energy ,such as gas cylinder, pneumatic motor, steam engine etc. The pneumatic element is a power driven form, which is also an energy conversion device, using the pressure force of the gas to transmit the energy. We could provide safety valve, check valve, two three way solenoid valve, water separating gas filter, throttle valve, quick exhaust valve, pressure regulating valve, muffler, pressure sensor ,oil -water separating device etc.
