Service units and function fittings
Miscellaneous articles
Aventics service units and functional fittings include compressed air service units of the 0821300xxx/0821301xxx series, flow control check valves (screwed type 0821200225-0821200231, block type 5341050000/5341061000), throttle valves in screwed and block form (0821201007-0821201109), and further functional fittings. These components regulate flow rate, pressure, and flow direction in pneumatic circuits and are designed for direct installation into line connections and valve stations.
| Type | Function | Form |
|---|---|---|
| Flow control check valve 0821200xxx | Flow control in one direction, free flow in the reverse direction | Screwed (cylinder port) |
| Flow control check valve 5341050000/5341061000 | Same function, compact inline form | Block (inline) |
| Throttle valve 0821201007-0821201109 | Bidirectional flow restriction without check function | Screwed and block |
| Service unit 0821300xxx/0821301xxx | Filtration, pressure regulation, air lubrication | Modular system, series |
Typical applications: Stroke speed control on pneumatic cylinders (flow control check valves), compressed air preparation at system inlet (service units), flow rate control in control circuits without directional requirement (throttle valves), and inline throttling in hose and piping systems.
