SMC ASP Series Speed Controller Flow Regulator, 1/4 in R R 1/4 in One-touch Fitting 8 mm

SMC ASP Series Flow Regulator, 1/4 inches Inlet Connection size, 8mm Outlet Connection size - ASP430F-02-08S

This flow regulator is a pneumatic speed controller designed to control Airflow in industrial systems. It connects to a 1/4 inches R inlet and discharges via an 8mm one‑touch fitting, providing adjustable flow control for Air lines operating within typical workshop and factory conditions.

Features & Benefits

• Operates across a working pressure range 0.1–1 MPa for flexible control
  Maximum temperature rating 60°C enables use in warm environments
  Proof pressure 1.5 MPa provides margin against pressure spikes
  Brass and stainless steel parts resist wear in pneumatic circuits
  Elastomer and polymer Seals ensure consistent modulation and sealing

**Applications**

• Suitable for speed regulation of pneumatic actuators in automation systems
  Ideal for controlling Airflow to valves in electrical panel ventilation
  Used with compressed Air lines in mechanical assembly stations
  Can be used for damping motion in electronic test rigs

What connection types are provided for straightforward installation?

The unit accepts a 1/4 inch R threaded inlet and an 8mm one‑touch outlet for Rapid tubing connection without additional fittings.

Which materials contact the medium and affect durability?

Flow path components include brass, stainless steel, POM and polybutylene terephthalate with NBR seals, combining metals and polymers for balanced wear resistance.

What operating temperatures and pressures should I expect during use?

Normal operation is suitable between -5°C and 60°C and within 0.1–1 MPa
transient conditions up to 1.5 MPa are covered by the proof pressure.

Is this regulator intended for hazardous-area installations?

It is not certified for hazardous‑area use and should be installed only in appropriate non‑hazardous locations.

Notes

Use caution with soft nylon or polyurethane at maximum pressure.
