SC Series Control-in & Control-out Throttle Valves

Adjustable Airflow for Controlled Cylinder Movement

The SC Series pneumatic speed controllers regulate the airflow entering or leaving a cylinder, allowing users to adjust actuator speed according to equipment requirements. Their compact one-touch design combines tube connection and flow adjustment in one fitting, helping reduce installation space and simplify pneumatic circuit layouts.

Control-in and Control-out Options

The SC Series includes two configurations for different airflow control requirements:

● Control-in: Restricts airflow from port B to port A while allowing free airflow from A to B. This configuration controls the air entering the actuator.

● Control-out: Restricts airflow from port A to port B while allowing free airflow from B to A. This configuration regulates exhaust air and is commonly used for stable cylinder speed control.

Both versions provide adjustable, unidirectional flow control for pneumatic actuators.

Specifications and Connection Compatibility

SC pneumatic speed controllers support a range of tube and thread connections for different equipment designs.

Applications and Installation

These pneumatic flow control valves are suitable for automation machinery, pneumatic cylinders, material handling equipment, assembly systems, and other applications requiring adjustable actuator speed.

Installation guidelines:

● Select Control-in or Control-out according to the required airflow direction.

● Match the tube diameter and thread type to the connected components.

● Insert the tube fully into the one-touch port and secure the threaded connection.

● Adjust the flow control gradually while observing cylinder movement, then verify operation under normal working conditions.

Choosing the correct control direction and connection size helps maintain predictable cylinder movement and reliable pneumatic system performance.
