Coaxial Valve pneum. direct
Series 2/918-..-10-R280
Valve 2/918-28/1024/8280-NJ-1E
2/2-way pneumatic direct operated coaxial valve also for highly viscous, lubricating or contaminated media. Type 2/918 valves are preferably used where seat valves cannot be used due to the fluid properties. Another argument in favour of this design is that it can be flowed through and shut off in all directions and can be installed in both horizontal and vertical pipelines.
