Compact one-way flow control valve, exhaust metering, G 1/8", 4 mm tube, nickel-plated brass

This compact one-way flow control valve sets the speed of double-acting pneumatic cylinders by throttling the air that leaves the cylinder. In the metered direction the adjusting screw limits the volume flow, while in the opposite direction the air passes freely through the built-in check valve. It is connected by a G 1/8" male thread and a push-in fitting for tubing with an outside diameter of 4 mm. An operating pressure range of -0.95 to 20 bar also covers vacuum duties. Metering the exhaust air gives the piston an even stroke without stick-slip behaviour.

Benefits

• Overall height about 30 percent lower than on standard flow control check valves
• Body made of nickel-plated brass and PA 66, seal made of NBR
• Operating pressure from -0.95 to 20 bar, therefore suitable for vacuum
• Temperature range from -20 to +80 °C
• Adjustment without tools, locked by pressing the cap
• Stainless steel gripping claws hold the 4 mm tube securely

Applications

• Speed setting on double-acting cylinders with a G 1/8" port
• Handling and assembly equipment with little installation space
• Packaging machinery running at high cycle rates
• Vacuum equipment down to -0.95 bar
• Test rigs operated with compressed air or neutral gases
