Directional control valves
In fluid technology, directional control valves are used to open or block the passage for service media like compressed air or hydraulic fluid or to change the flow direction.
The valves are actuated electrically, pneumatically, mechanically or manually. Our product range includes 5/2-way and 3/2-way valves with ¼ inch connections or special sizes, which can be flanged directly to the assembly according to VDI/VDE 3845. For high safety requirements, redundant versions are available.
Electro-magnetically actuated and directly controlled poppet valves are suitable for a wide range of service media: filtered, oil-free and dried compressed air, instrument air, nitrogen and other non-combustible, neutral, dryfluids (for versions suitable for liquid and aggressive fluids, please enquire).
Poppet valves have TÜV approval certificates based on IEC 61508 and DINV19251 and can be used in safety-relevant systems up to SIL4 and AK7* as well as in the applicability ranges of explosion protection types EEx me. EEX md, XP (Div 1) in zones 1, 2 (gases), 21, 22, dusts) ATEXCat. II 2GD.
The valves are mainly used for control of single- and double-acting pneumatic process.
