Hafner manufactures pneumatic (low pressure) directional control valves.
These pneumatic valves can be operated manually, pilot or electrically as solenoid valves, or a combination of these.
Different sizes and designs can be assembled into customized pneumatic solutions.
The valves can also be delivered in complete AISI 316 material including the coupling body which can be delivered with EEX d, EEx ia or EEX me ATEX certificates   Hafner has a wide range of pneumatic valves from 1/8” to 3/4” as 2/2, 3/2, 5/2 or 5/3 configurations that impress with their compact design and their low operating force through their patented sealing solution.
