Pneumatic Flow Controllers Include Shock Absorber Function

Pisco’s pneumatic flow controller features a built-in shock absorber function.

Pisco’s pneumatic flow controller features a built-in shock absorber function. The flow controller uses a two-stage speed control to regulate exhaust speed and to absorb shock in pneumatic cylinders. The controllers are available in 4-, 6- and 8-mm as well as ¼" and 5/16" sizes.

The controllers have three needles to adjust the initial speed of the cylinder (first stage), speed of the brake (second stage) and timing of the speed shift. The second-stage speed provides a cushion and reduces the speed at the end of the stroke. This speed reduction also lessens shock while retaining the same cycle time. According to the company, the two-stage speed controllers last three times longer than a system equipped with conventional shock absorbers and require less maintenance. In a system that uses conventional shock absorbers and Pisco’s flow controllers, it is possible to actuate the initial cylinder stroke at twice the regular speed and then actuate the end of the stroke at the regular speed to reduce cycle time without increasing shock.
