Fastek USA Solenoid Valve Model N4H-310-08-S

Function:

        This is a 5 ported 4 Way Directional Control Valve used to move cylinders or actuators.  Supply pressure should 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.  The pressure will hold the cylinder in one position while the other side of the cylinder is exhausted.  Shifting the lever will cause the valve spool will shift causing air to go to the opposite side of the cylinder while exhausting the side that was pressurized.  This causes the cylinder to shift (or extend).  When the lever is shifted back (released), a spring will return the spool causing the cylinder to return to it's "at rest" position.  Mufflers may be added to the exhaust ports to quiet the air exhausting.  Adjustable 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 4H310-08-S.
