Series HG - 2

The WALTHER high pressure refueling systems of the HG series were developed for safe and fast refueling with gaseous hydrogen. The usual application is the refueling of vehicles with fuel cell drive up to an operating pressure of 875 bar. The refueling nozzles are tested and validated to SAE J2600:2002 - 70 MPa, the worldwide standards of the refueling interface. WALTHER-PRÄZISION has significantly contributed to the achievement of the standard and thus set the standard of highpressure sealing in 2006. We are offering a validated technology for the mobility of the future.
