Pneumatic valves are usually run by air captured during a previous or ongoing process. Since they are being used to trigger larger valves and aren't requiring more cost, they are a cheaper economical way to power a solenoid valve. Compressed air can result in huge forces available to act on another valve and be recycled after its done its job. With compressed air-driven pneumatic valve is the valve. Only clear when the pneumatic valve procurement specifications, type, working pressure to meet the procurement requirements of the practice, in the current environment of market economy is incomplete.

  Pneumatic actuation refers to a valve being tripped through the use of compressed air (gas). At a particular point in an industrial or manufacturing process, compressed air is released, causing a valve to open or close. The combination of solenoids and pneumatics is twofold. Solenoid valves are used in pneumatic processes and solenoid valves and pneumatic valves are used in combination. The combined valve is called a piloted valve. The larger solenoid valve is triggered by the smaller pneumatic valve. The pneumatic valve can act as an air cylinder contained in a main valve. A pneumatic solenoid valve is also referred to as a compressed air pilot valve.
