Elbow one-way flow control valve, exhaust metering, G 1/2" to 10 mm tube, nickel-plated brass

This elbow one-way flow control valve sets the extension or retraction speed of a pneumatic cylinder by throttling the air that leaves the chamber. It is screwed straight into the cylinder port with its G 1/2" thread, while the line with 10 mm tube outside diameter is pushed into the plug-in connector. A screwdriver-adjustable needle acts in the metering direction, and the built-in check valve releases the full cross section in the opposite direction. With a working range from -0,95 to 20 bar the valve covers vacuum duties as well as ordinary compressed air networks. Because the exhaust side is metered, the piston always rests against an air cushion and moves without stick-slip.

Advantages

• Exhaust metering keeps cylinder travel even at operating pressures up to 20 bar
• Working range of -0,95 to 20 bar, which also permits use under vacuum
• Valve body in nickel-plated brass combined with a release ring made of PA 66
• Stainless steel gripper claws retain tubing with 10 mm outside diameter
• Needle adjustable with a screwdriver only, so the chosen speed stays where it was set
• Temperature range of -20 to +80 °C, NBR seal and silicone-free lubricants

Applications

• Speed setting on pneumatic cylinders in handling axes
• Clamping and joining fixtures in tooling with a G 1/2" port
• Packaging and special purpose machines with long 10 mm tube runs
• Vacuum equipment, since the working range extends down to -0,95 bar
