What is a Pneumatic valve?

A pneumatic valve is a valve that regulates air pressure or a valve that uses air pressure (actuator). Among them, this article describes pneumatic relief valves/safety valves and pneumatic actuators/pneumatic valves. A pneumatic relief valve is a pneumatic valve used to protect the compressor when the pressure in a compressed air system containing the compressor becomes too high. Among the many different types of safety/relief valves, especially those involving compressed air, the operating pressure level is set below the maximum pressure the compressor can withstand. When the compressor pressure is about to reach this maximum pressure, a relief valve allows air to escape, allowing the pressure to drop. It releases pressure when it reaches a critical point and is also called a pressure relief valve. The pneumatic relief valve has a very simple mechanism and is designed to operate reliably. A pneumatic actuator is a switching valve that opens and closes a valve using the power of pneumatic pressure. The advantage is that the structure is simple, so it is easy to manage, and a large output (driving force) can be easily obtained.
