The stroke speed of a pneumatic cylinder is normally governed by the exhausted air volume rather than by pressure. That is the job of this exhaust metering one-way flow control valve, which is screwed straight into the cylinder port and takes tubing with an outside diameter of 3 mm. In the metering direction the adjusting screw defines the air volume, while in the opposite direction the check element opens and lets air pass freely. The working range extends from -0.95 bar under vacuum up to 10 bar gauge pressure at 0 to +60 °C. For cylinders with a very small volume the supply metering version is used instead.
Benefits
- Even cylinder motion free of stick-slip thanks to exhaust metering
- Body in nickel-plated brass and PA 66 for durable threaded joints
- Push-in fitting for 3 mm tubing with stainless steel gripping claws
- Pressure range of -0.95 to 10 bar covers vacuum and gauge pressure duty
- Metering screw adjustable without tools, seal made of NBR
- Assembled exclusively with silicone-free seals and lubricants
