ECO pressure reducing valve with integrated gas-saving valve

ECO pressure reducing valve with integrated gas-saving valve


Pressure regulator ECO with built-on flowmeter and integrated gas economizer. The pressure regulator ECO was especially designed to minimise the non-productive gas consumption which occurs at the beginning of every welding operation with MIG, MAG and WIG welding and hence reduce the costs of inert gas arc welding.

The shorter the welding intervals, the greater the savings, because when using pressure regulators without integrated gas economizer there is a pressure build-up each time a welding operation is interrupted, resulting in non-productive gas consumption on each activation of the welding process. Non-productive gas consumption can be reduced by more than 50% by using the integrated gas economizer.

A higher weld quality is also obtained as a result of the uniform gas flow.
