The Rexroth S72 748 0670 7290 is a 5/2-way single solenoid pilot-operated valve. The “5/2” means it has five ports and two switching positions. It is a monostable valve, meaning it has one stable position and returns to it automatically when the electrical signal is removed (spring return).
It is designed for use in industrial pneumatic systems to control the direction of compressed air to actuators like cylinders or rotary actuators.
