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

Where space above the cylinder port is tight, this compact one-way flow control valve replaces the taller standard design. Overall height drops by roughly 30 % while the function stays the same, namely metered exhaust and free flow in the supply direction. The connection uses a tapered R 1/4" thread together with a tube of 8 mm outside diameter. Once the speed is set, the cap locks by simply pressing it down, so the adjustment survives vibration. The permitted pressure range runs from -0.95 to 20 bar.

Advantages

• Around 30 % lower overall height than a standard one-way flow control valve, which helps inside narrow gantries.
• The adjusting cap latches when pressed and secures the setting without a lock nut.
• Housing in nickel-plated brass and PA 66 with a zinc plated ZnDC cartridge.
• Pressure range from -0.95 to 20 bar at temperatures from -20 to +80 °C.
• An R 1/4" port with a push-in connection for 8 mm tube saves a separate fitting.
• Silicone free seals and lubricants during assembly suit an environment close to paint shops.

Applications

• Short stroke cylinders with an R 1/4" port underneath low guards and covers.
• Grippers and swivel units on gantries where every millimetre of height counts.
• Feeding and separating stations with cylinders mounted close together.
• Machines with strong vibration in which a plain metering screw tends to drift.
• Systems using 8 mm tubing in the pressure range up to 20 bar.
