How many ports does a quick exhaust valve typically have?

A quick exhaust valve typically has three ports. These ports consist of one port for the inlet air, one for the outlet air to the actuator, and one for venting the exhaust air. The design of the valve allows for rapid exhaust of air from the actuator, significantly increasing the speed of operation while utilizing a smaller volume of air. This functionality is crucial in applications where quick actuation is needed. So, having three ports enables the valve to effectively manage the flow of air, ensuring that the system operates efficiently and responsively.
