Keep valves clean

To help operators deal with this issue Smith Flow Control has developed a range of dust plugs and vinyl bags.

 


Dust plugs are a simple and effective way to prevent dust and dirt ingress into key interlocks. Made from high density polyethylene (HDPE) and fitted with a ‘soft sealing’ aperture gasket, the plug is inserted into the key aperture as soon as one of the coded keys is removed. By creating a tight fit, the plug seals the aperture and will not become dislodged, allowing the operator to complete the assigned task.

 

Vinyl bags envelop the complete interlock unit and protect key aperture points and lock bodies. Weather- and dust-proof, they also have UV protection so they don’t deteriorate in the sun. The bags can be fitted to both handwheel- and lever-operated valves and a drawstring allows them to be closed and attached to the interlocked valve.
