What Is a Pneumatic Timer?
A pneumatic timer is a device that controls air input signals.
Its distinctive feature is that it does not require electrical wiring, eliminating risks such as electrical leakage. It is used in places where the use of electricity and electrical currents is undesirable, such as in oil refineries. The pneumatic timer consists of a piston and control valves, and is also known as a time-delay valve.
It allows for the setting of time, and after the set time has elapsed, the ports switch. However, it is suitable for light tasks around 1 ton of pressure, but becomes challenging for heavier tasks. Generally, it uses a chamber and piston, though other mechanisms can also be employed.
