Imported pneumatic precision small regulating valve
Overview of imported pneumatic precision small regulating valve products
YLOK imported pneumatic thin film fine small flow regulating valve (imported pneumatic fine small flow regulating valve, imported fine small pressure regulating valve) is a small diameter regulating valve specially developed for small flow regulation. The valve body adopts threaded connection, which has the advantages of small size, light weight, convenient installation and maintenance. When adjusting the dirty medium, the problem of small throttling gap should be taken into consideration to prevent jamming. It is suitable for the occasion of adjusting the flow rate of liquid, steam and other media.
