SMC 10-AS1201FG-U10/32-07A | 10-AS-FG Series Clean Room Push-Lock Speed Controller Stainless Steel Elbow/Universal Body 1 One-Touch Fitting

The SMC 10-AS1201FG-U10/32-07A is a clean room specification push-lock type speed controller from the 10-AS-FG series, featuring stainless steel construction with an elbow/universal body configuration and integrated one-touch fitting. Speed controllers (also known as flow control valves or needle valves) regulate the speed of pneumatic cylinders and actuators by controlling the exhaust or supply air flow rate, enabling precise motion speed adjustment for clean room automation equipment.

What does the "FG" stainless steel designation mean for clean room applications? The FG suffix indicates this speed controller is constructed with stainless steel wetted parts instead of standard brass components, providing superior corrosion resistance and eliminating copper-based materials that can generate contaminating particles in clean room environments. Stainless steel construction also prevents galvanic corrosion when used with DI water-adjacent systems or in environments with chemical vapor exposure.

The "push-lock" feature allows the flow rate to be set and then locked in position by pushing the adjustment knob, preventing accidental speed changes from vibration or incidental contact during production. The elbow/universal body style ("U" designation) provides flexible mounting orientation for routing tubing in confined clean room equipment enclosures. The "10/32" thread and "07A" fitting specification configure the port connections for the target tubing size.

The "10-" clean series ensures fluorine grease, clean room workshop assembly, and anti-static double packaging. This speed controller is RoHS compliant and designed for integration into clean room pneumatic cylinder and actuator circuits alongside SMC clean series regulators and valves. Body size 1 indicates the most compact form factor in the series.
