SMC ASP Series Speed Controller Speed Controller, 1/2 in R R 1/2 in One-touch Fitting 12 mm

SMC ASP Series Speed Controller, 12mm Outlet size, 1/2 inches Inlet Connection size - ASP630F-F04-12S

This speed controller provides adjustable pneumatic flow control for industrial automation systems, designed to regulate actuator speed in compressed-air circuits. It integrates corrosion-resistant materials and a Compact form suited to panel or inline installations where stable flow control between low and moderate pressures is required.

Features & Benefits

• Operates across 0.1–1 MPa to control actuator speed precisely
  Withstands proof pressure of 1.5 MPa for a safety margin during surges
  Rated for continuous use to 60°C in typical plant environments
  1/2 inches R inlet simplifies connection to standard supply lines
  One-touch 12mm outlet enables Rapid tubing attachment and removal
  Constructed from polypropylene, NBR, stainless steel and brass for durability

**Applications**

• Suitable for cylinder speed control in assembly-line automation
  Ideal for pneumatic valve pilot flow adjustment in control panels
  Used for hose-fed tools requiring quick tubing changes
  Can be used for laboratory pneumatic rigs needing repeatable flow settings

What connection types are provided for supply and delivery?

The inlet uses a 1/2 inches R threaded connection compatible with R-standard fittings while the outlet accepts a 12mm one-touch tube fitting for simplified hose hookup.

Which materials contact the fluid and why does that matter?

Fluid-contact parts include polypropylene and NBR Seals Plus stainless steel and brass elements, chosen to balance chemical compatibility and wear resistance in compressed-air systems.

How does the device handle pressure variations common in workshops?

It is specified to operate down to 0.1 MPa and up to 1 MPa with a 1.5 MPa proof pressure, providing a design margin against short-term overpressure events.

Is the product suitable for higher-temperature processes?

The unit is rated for a maximum continuous operating temperature of 60°C, so it should be used within that thermal limit for consistent performance.

Notes

Use caution with soft nylon or polyurethane at maximum pressure.
