Exceptional welding system control
Case Study
A leading welding systems manufacturer required an
adaptable high performance valve to pilot the actuators
controlling the welding tip system onboard robotic welders
for the Automotive Industry. The solution had to provide:
> High Resolution
> Fast response <120ms
> Configurable
Norgren Engineers offered a standard VP51 into the
system where it successfully performed to and beyond the
customer's initial specification. The exceptional response
control of the VP51, less than 80ms, combined with the
high resolution meant that the overall system could move
to a work piece much quicker and position the tip precisely
producing more accurate and repeatable welds.
VP51
Digital closed loop proportional valve enhancing proven
spool and pilot technologies. Digital interface allows end
user modification to all parameters including , language,
pressure range and reponse. Ideally suited to general purpose
industrial pressure control applications requiring precise
customising to ensure optimum system output and quality.
