Flow controllers: Speed controllers & Needle valves  2 Stage Speed Controller with Built-in Shock Absorber Function
 


Industry first - Flow controllers are used to control the speed of pneumatic cylinders. Shock absorbers are mounted on the cylinder to act as a break. Pisco’s new flow controller uses a 2 stage speed control to control the exhaust speed which acts a cushion (brake) and functions as a shock absorber.

  • Lasts 3x longer, cost savings - Last 3x longer than a system using conventional shock absorbers and requires less maintenance. In a conventional system, shock absorbers need to be frequently replaced. Significant cost savings over the life of the product.
  • Reduce shock - With the 2 stage flow controller, the 2nd stage speed (speed of the exhaust) acts as a cushion and reduces the speed at the end of the stroke. This speed reduction also reduces the shock by up to 1/9 while keeping the same cycle time. (See catalog page 2 “shock absorbing effect chart”)
  • Shorter cycle time - It is possible to actuate the initial cylinder stroke at twice the regular speed and then actuate the end of the stroke at the end of the stroke, reducing the cycle time without increasing the shock. (See catalog page 2 “cycle time chart”)
