Angle flow control check valve, supply air metering, R 1/4" to 8 mm tube, nickel-plated brass

Flow control check valves meter the air in one direction only, while the check element lets it pass freely in the opposite direction. This version meters the supply air and is used where exhaust metering reaches its limit, namely on cylinders with a small volume caused by a small bore or a short stroke. The valve is screwed straight into the cylinder port with its R 1/4" thread and accepts tube with an 8 mm outside diameter. The body is made of nickel-plated brass and PA 66, and the operating pressure range runs from -0.95 to 20 bar. Only silicone-free seals and lubricants are used during assembly.

Advantages

• Supply air metering gives smooth travel on small cylinder volumes without stick-slip effects.
• Operating pressure range of -0.95 to 20 bar, which also covers vacuum applications.
• Nickel-plated brass and PA 66 body with stainless steel gripping claws that hold the 8 mm tube securely.
• Temperature range of -20 to +80 °C, considerably wider than that of all-plastic fittings.
• The throttle screw is adjusted without tools, which shortens commissioning.
• Assembly with silicone-free seals and lubricants suits painting and bonding processes.

Applications

• Speed adjustment on short stroke cylinders and small bore cylinders.
• Grippers and clamping fixtures that have to close without jerking.
• Installations with a silicone-free requirement, for example ahead of painting or bonding cells.
• Vacuum equipment down to -0.95 bar, such as suction cup rails.
