Air Line Push-In Union Speed Controller – NSCU Series


Pneumatic Tube-to-Tube Speed Controller

The NSCU Series pneumatic speed controller provides adjustable unidirectional air flow control between two equal-size push-in tube connections.

Designed for controlling the speed of pneumatic cylinders and actuators, the integral needle adjustment allows the air flow rate to be regulated in one direction while permitting freer flow in the opposite direction.

Available for 4mm, 6mm, 8mm, 10mm and 12mm pneumatic tube.

One-Touch Push-In Connections

Push-to-connect fittings at both ends provide quick installation of Nylon or Polyurethane pneumatic tubing. Tubing can be released by pressing the retaining sleeve and withdrawing the tube.

Adjustable Unidirectional Flow Control

The integral needle valve provides adjustable flow restriction in one direction, allowing controlled regulation of pneumatic actuator or cylinder speed.
The straight tube-to-tube configuration is particularly useful where speed control is required within an air line rather than directly at a cylinder or valve port.

Integrated Mounting

The POM body incorporates mounting holes, allowing the speed controller to be securely fixed to machinery, panels or other suitable mounting points.
