The Festo MS4-EM1-1/4-S-Z is a 3/2 bistable pneumatic control valve used to switch and control air flow in compressed air systems. It is typically installed in machine control panels where air signals must remain in position even after the control signal is removed. Once switched, the valve remains in its last state until it is actively changed again. This makes it worthwhile in systems where maintaining the last air state is essential for safety, process control, or machine operation.
This valve operates in a 3/2 configuration, meaning it has three ports and two switching positions. The bistable design allows the valve to hold its position without continuous air or electrical input.
The MS4-EM1-1/4-S-Z is designed to fit neatly into Festo MS4 modular air preparation systems. The 1/4-inch port size makes it suitable for many standard pneumatic setups found in industrial automation and machinery.
This valve is typically used in applications such as:
