- Valves with fail-safe function
- Maximum air flow with compact design
- Different NAMUR mounting port schemes
- Valves with a ¼” (VDI / VDE 3845) as well as ½” NAMUR interface
- Valves with SIL3 and Ex certification, for -50°C and entirely made of AISI316 stainless steel
- Wide range of accessories such as NAMUR flow regulator plates, quick exhaust valves, block and vent valves and many more
Our bestsellers: 3/2-way and 5/2-way NAMUR valves in different sizes:
 |

NAMUR-Flex The NAMUR-flex is designed for a maximum of flexibility. The valve itself can be used as a 5/2-way type on double acting actuators. |
 |
Quick-exhaust blocks The quick-exhaust block with NAMUR interface allows big spring-return actuators to close at high speed. It offers a maximum exhaust volume of 2,500 Nl/min. An integrated non-return valve ensures that no ambient atmosphere can be sucked into the actuator while exhausting. |
 |
Short-cut valve In the case of automated process valves which are equipped with a manual gear box, it has to be ensured that no air is trapped inside the actuator in case of manual operation. |
 |
NAMUR flow regulator plates Block form flow regulator as intermediate plate to be assembled between actuator and pilot-valve.
