SMC ASP Series Speed Controller Flow Regulator, 1/8 in R R 1/8 in One-touch Fitting 8 mm

SMC ASP Series Flow Regulator, 1/8 inches Inlet Connection size, 8mm Outlet Connection size - ASP330F-01-08S

This flow regulator provides controlled adjustment of pneumatic airflow for speed regulation in automated systems. It is designed for inline installation with a 1/8 inches R inlet and an 8mm one‑touch outlet, functioning across typical industrial pressure and temperature ranges to modulate actuator or cylinder motion.

Features & Benefits

• Maximum operating pressure 1MPa offers robust system compatibility
  Proof pressure 1.5MPa improves safety margin during pressure spikes
  Operating range from -5°C to 60°C maintains performance in varied climates
  Minimum operating pressure 0.1MPa enables fine control at low supply pressures
  Zinc chromated body with NBR Seals resists corrosion and leakage
  Stainless steel and brass components enhance durability in pneumatic circuits

**Applications**

• Suitable for controlling cylinder extend and retract speeds in automation
  Ideal for tuning actuator motion in electrical panel assembly lines
  Used with pick‑and‑place equipment for precision handling adjustment
  Can be used for flow tuning in pneumatic test rigs and benches

What connection types are provided for integration with tubing?

The inlet uses a 1/8 inches R threaded connection while the outlet accepts an 8mm one‑touch fitting for quick tube attachment.

Which materials contact the fluid flow and help prevent wear?

Flow path components include stainless steel, brass and POM alongside nitrile rubber sealing to balance wear resistance and sealing integrity.

How does the component behave under transient overpressure events?

It withstands up to 1.5MPa proof pressure without structural failure, providing a margin above normal operating pressure.

What minimum supply conditions are needed for reliable speed control?

Effective regulation is achievable down to 0.1MPa supply pressure, enabling control in low‑pressure systems.

Notes

Use caution with soft nylon or polyurethane at maximum pressure.
