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

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.

• 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

• 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

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

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

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

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

Use caution with soft nylon or polyurethane at maximum pressure.
