Fastek USA Solenoid Valve Model N4V-230E-08

Function:

        This is a 5 ported 4 Way Directional Control Valve used to move cylinders or actuators.  Supply pressure must be supplied to the center port on the side of the valve with the 3 ports.  The outlet ports on the opposite side are connected to each side of a cylinder or actuator.  There is no pressure to the cylinder ports when valve is in the center position.  When voltage is applied to one solenoid, the valve spool will shift causing air to go to the one side of the cylinder while still exhausting the opposite side of the cylinder.  The cylinder will shift (or extend).  When the voltage is removed, a spring will return the spool to center causing the  cylinder to return to it's "at rest" position.  When Voltage is applied to the opposite coil, the cylinder will shift in the opposite direction.   Exhaust restrictors may be used to in the exhaust ports to control the speed of the cylinder.  If flow controls are used, they should always be placed in the lines between the cylinder and the outlet ports and control the air flow as it exhausts from the cylinder.  This valve may be used to replace a 4V230E-08.
