SMC ASP Series Speed Controller Speed Controller, 3/8 in R R 3/8 in One-touch Fitting 8 mm

SMC ASP Series Speed Controller, 1 Mpa Maximum Operating Pressure, 60°C Maximum Operating Temperature - ASP530F-F03-08S

This speed controller is a Compact pneumatic device designed to regulate airflow in industrial automation systems. It is intended for use where controlled cylinder or actuator motion is required and provides bidirectional flow control via a one-touch outlet connection. Constructed using a mix of engineered plastics and metals, the unit suits general factory and equipment panel installations without hazardous-area certification.

Features & Benefits

• Maximum operating pressure 1MPa provides stable flow control under load
  Proof pressure 1.5MPa increases safety margin during pressure surges
  Operating temperature range -5°C to 60°C supports varied workshop conditions
  One-touch 8mm outlet enables quick hose connection and removal
  3/8in R inlet thread allows straightforward piping integration
  Components include brass and PBT for corrosion resistance and durability

**Applications**

• Suitable for regulating pneumatic cylinder speed in assembly lines
  Ideal for motion control in pick-and-place equipment
  Used for flow adjustment on air-driven testing rigs
  Can be used for speed tuning in valve actuator set-ups

What materials contact the pneumatic medium inside the valve?

Internal wetted parts comprise brass, nitrile butadiene rubber and polyoxymethylene to balance wear resistance and sealing performance.

How does the inlet thread standard affect installation?

The inlet uses a 3/8in R threaded connection, compatible with standard R-thread fittings for simple integration into existing pipework.

Is the unit suitable where higher-than-normal pressures occur briefly?

It tolerates short-term excursions up to the 1.5MPa proof pressure, providing margin above the 1MPa normal operating limit.

What flammability characteristic does the housing meet?

The polymer components conform to UL V-0 requirements for reduced flammability risk in electrical and control enclosures.

Notes

Use caution with soft nylon or polyurethane at maximum pressure.
