Pressure regulating proportional valves
Published: 13 July 2012 - Heather Ramsden
The range of proportional valves from Norgren, a specialist in pneumatic motion and fluid control technology, comprises high-performance products which enable flexible control of both pressure and flow.
Pressure-regulating proportional valves are used in a variety of applications such as spot welding to control electrode clamping force; dancer roller applications to control the position of the roller on winding machines, and for leak testing.
In spot welding, proportional valves enable fast response times with accuracy as clamping forces alter in line with changing welding parameters.
With dancer rollers, proportional pressure regulation allows accurate resolution between input signal and output pressure, enabling the dancer roller system to accumulate material as line velocity varies and maintain the correct tension during the winding process.
Areas of application for flow-controlling proportional valves include the positioning and speed control of cylinder movement.
