The PSS802A features a unique labyrinth throttle design for ultra-fine flow adjustment, with corrosion-resistant construction and tool-free calibration. Its swivel joint maintains seal integrity through 340° rotation, enabling flexible piping arrangements. Includes dual-scale flow indicators (0-5 and 0-100 markings) for precise coarse/fine tuning.
- Pneumatic cylinder speed regulation in pick-and-place systems
- Exhaust flow control for shock absorption in press machinery
- Multi-axis robotic arm pneumatic sequencing
- Medical bed actuator speed modulation
- Packaging line gripper synchronization
Adjustment protocol:
Rotate counterclockwise for increased flow (max 20L/min). For stable control,
always set flow 20% above minimum required and perform final tuning under load.
Lubricate rotating collar annually with silicone grease (ISO VG 10).
