Smith Flow Control Develops Dust Plugs And Vinyl Bags To Keep Valves Working In Harsh Environments
- Mar 23, 2018 -

When working in the most extreme environmental conditions (such as desert or sea), keeping the valve free from sand and salt will be a worthless task.

To help operators deal with this issue, Smith Flow Controls has developed a series of dust plugs and vinyl bags that protect the interlocking from the worst elements, even in the harshest environments.

Dust plugs

Dust plugs are a simple and efficient way to prevent dust and dirt from entering the key interlock, which are made of high density polyethylene (HDPE) and equipped with a "soft-seal" bore gasket. Once one of the coded keys is removed, the plug is inserted into the keyhole. By creating a tight fit, the plug seals the aperture and does not fall off, allowing the operator to complete the assigned task.

Vinyl bags

A simpler solution, these sturdy covers the complete interlocking unit and protect the keyhole and lock body. They are weather- and-dust-proof and also have UV protection so they do not deteriorate in sunlight. These bags can be mounted on hand wheels and lever operated valves, which can then be tightly closed and securely attached to the interlocked valves.

Both of these products are easy to use and provide a powerful physical barrier that reassures the operator whether or not the components are thrown in the valve interlock.
