High-quality pneumatic solenoid valve from Mindman. This valve is 5/2 way and bi-stable (2 coils). The valve has G1/4" ports (BSPP thread). The coil voltage is 24V DC and the power is 4.9VA. Please note that the exhaust ports have G1/8" threads, they are smaller than the other ports. The valve can only be operated with compressed air (filtered up to 5 μm) that doesn't need to be lubricated. The operating pressure is 2 to 8 bar. This valve has a Namur configuration, allowing it to be mounted directly to a pneumatic actuator without hose connection. Response time is 0.038 s. Kv value 0.8 (862Nl/min). This valve is equipped with a manual override.
A 5/2-way valve has five ports and two states. Two ports (A and B) connect to the appliance, for example a double acting cylinder. One port is used to supply pressurized air (port P), the two remaining ports are exhausts (port S and R) and are connected to respectively port B and A. By switching state, either port A is pressurized and port B vented, or port A is vented and port B pressurized. If the valve is used to control a double acting cilinder, one valve state is used to move the cylinder in one direction, and the other state is used to move the cylinder in opposite direction.This valve is double acting, which means that the solenoid valve is controlled by two solenoids. The solenoids are pulse operated and can each control a valve state. If both solenoids are not activated, the valve remains in the last state. Therefore, the valve is bi-stable.

Namur (VDI/VDE 3845) defines a standard interface between pneumatic directional valves and actuators. The solenoid valve has two O-rings to create a leak-tight connection between the valve and the actuator. The solenoid valve can be rotated 180 degrees, this determines whether the actuator is pressurized or vented when the solenoid is activated. The illustration below shows the dimensions of the connection for both G1/4" as G1/2".
