At TBMA we continue to develop our products. Because only then can we respond to the increasing demands on our products. For example, when rotary valves are used during production in an ATEX environment, where there is a risk of explosion.

The results of our efforts are now rewarded with an ATEX certification for our H-GR valves. The TBMA H-GR valves are suitable for a much wider scope within the ATEX area.
