Metric Tube Flow Controls Push To Connect Fitting

Control Cylinder Speed Directly at the Actuator Port

JSC Series pneumatic flow controls combine a push-to-connect tube fitting with an adjustable one-way restriction for controlling actuator speed. They are commonly installed on pneumatic cylinders where exhaust flow can be metered to produce a smoother, more progressive stroke.

Unlike a simple needle valve, a pneumatic flow control restricts flow in one direction while allowing substantially freer flow in the opposite direction. This makes it especially useful for meter-out speed control on double-acting and single-acting pneumatic cylinders.

This category is intended for metric-size pneumatic tubing.

Operating Specifications

• Fluid medium: Air
• Working pressure: 0–150 psi(g) / 10 bar(g)
• Proof pressure: 450 psi(g) / 30 bar(g)
• Vacuum duty: 29.5 inHg / 14 mbar(a)
• Working temperature: 32–140°F / 0–60°C

Why Use a Pneumatic Flow Control?

• Adjustable restriction helps tune cylinder extension or retraction speed
• One-way design provides controlled flow in one direction and freer return flow in the other
• Push-to-connect tubing simplifies installation and maintenance
• Useful for reducing abrupt actuator movement and improving machine motion
• Available in compact actuator-mounted and inline arrangements

Common Applications

• Pneumatic cylinder speed control
• Packaging machinery
• Automated assembly equipment
