Elbow one-way flow control valve, exhaust metering, R 1/4" to 12 mm tube, nickel-plated brass

This elbow one-way flow control valve in the standard exhaust metering version determines how fast a double-acting cylinder travels. The tapered R 1/4" male thread seals metal to metal in the cylinder port and saves additional sealant when it is fitted carefully. A tube with 12 mm outside diameter is joined through the push-in connector, and this cross section carries even longer runs without appreciable pressure loss. The permitted range of -0,95 to 20 bar includes vacuum operation. The metering screw can be turned by hand without any tool, which speeds up machine commissioning.

Advantages

• Metering screw adjustable without a tool, convenient during commissioning
• Tapered R 1/4" male thread for a sealing joint in the cylinder port
• Tube connection for 12 mm outside diameter with stainless steel gripper claws
• Body in nickel-plated brass and PA 66, cartridge in galvanised zinc die casting
• Pressure range of -0,95 to 20 bar, hence usable in vacuum circuits as well
• Temperature range of -20 to +80 °C with a seal made of NBR

Applications

• Stroke speed setting on pneumatic cylinders with an R 1/4" port
• Gantries and feeding units that are readjusted frequently
• Installations with higher air demand supplied through 12 mm tubing
• Vacuum grippers and suction systems operating down to -0,95 bar
