How to Move Pneumatic Cylinders Smoothly Without Shock Absorbers – Using Pisco’s 2-Stage Flow Regulator

In the world of industrial automation and motion control, achieving smooth, precise movement of pneumatic cylinders—especially at the end of the stroke—is critical for machine safety, longevity, and performance. Traditionally, engineers have relied on mechanical shock absorbers to dampen cylinder impact; however, these components add cost, increase maintenance, and reduce design flexibility.

Now, BJSU, there's a more innovative and more cost-effective solution. Pisco Japan introduces a breakthrough in pneumatic technology: the 2-Stage Speed Controller BJSU (Flow Regulator), a patented innovation (Patent No. 5578502) that enables smooth cylinder motion without the need for shock absorbers. This advanced component is RoHS2 compliant and designed for low-cost automation, making it ideal for projects across various industries.

What is the Pisco 2-Stage Flow Regulator?

The Pisco 2-Stage Flow Regulator is a compact, innovative pneumatic flow control device that allows two-stage air speed regulation inside a pneumatic cylinder:

• First stage: High-speed movement throughout most of the stroke.

• Second stage: Automatic slow-down as the piston nears the end of its travel.

This intelligent control prevents sudden stops or vibrations, eliminating the need for additional shock absorbers or dampers.

Key Benefits for Pneumatic Cylinder Applications

Here’s why Pisco’s 2-Stage Speed Controller stands out:

• No Shock Absorber Required – Reduce component cost, system complexity, and downtime.

• Smooth End-of-Stroke Motion – Improves reliability and prevents damage to the cylinder or frame.

• Low-Cost Automation Solution – Ideal for small and large automation projects.

• Compact Design – Fits into tight machine spaces.

• Simple Flow Adjustment – Easily fine-tune speed for varying loads.

• RoHS2 Compliant – Environmentally safe for global use.

Applications of Pisco 2-Stage Speed Controllers

The Pisco 2-stage flow regulator is ideal for pick-and-place machines, automated sliding doors, lifting mechanisms, and job transfer systems, particularly where smooth stopping is required.

Common Use Cases:

• Pneumatic Door Opening Systems – Quiet and smooth closing/opening without banging.

• Pick and Place Automation – Prevent sudden jerks at stroke ends in high-speed cycles.

• Job Movement on Conveyor Lines – Controlled deceleration for precise part placement.

• Vertical or Horizontal Lifting Cylinders – Avoid shock load at end position.

• General Pneumatic Automation – From packaging to assembly lines.

How It Works – Smooth Cylinder Motion in 2 Steps

1. Initial Stroke: High-speed airflow ensures fast actuation.

2. End Stroke: The Internal mechanism triggers controlled airflow, slowing down the piston gradually.

3. Result: A soft stop, just like using a shock absorber, without the extra component.
