Except the Quality Management System according to ISO 9001:2015 we have also, required by law, all product certificates. Due to changes in regulations in the field of transportable pressure equipment, we have finished the cylinder valves certification for compliance with the new Directive no. 2010/35/EC and EN13153 standard (the approval of construction type). All valves have a visible „Π” mark No. 1017. The certification was executed by TUV SUD CZECH REPUBLIC.
