When operating in the most extreme environmental conditions, such as deserts or offshore, keeping valves free from sand and salt can be a thankless task.
To help operators deal with this issue Smith Flow Control has developed a range of dust plugs and vinyl bags to keep interlocks free from the worst of the elements, even in the most hostile environments.
Dust plugs
Dust plugs are a simple and highly 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
A simpler solution, these robust covers envelop the complete interlock unit and protect key aperture points and lock bodies. They are weather- and dust-proof and 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 then to be tightly closed and firmly attached to the interlocked valve.
Both of these products are simple to use and provide a powerful physical barrier, whatever the elements are throwing at valve interlocks, giving operators peace of mind.
