Sentry Saf-T-Vise Atomizers

Sentry Saf-T-Vise Atomizers

Sentry Saf-T-Vise atomizers contain a patented safety feature to increase operator safety and deliver a customized user-experience.

The equipment features an easy-to-use collet that locks the shaft within the process stream in both low and extremely high-pressure conditions. In addition, a variety of atomizer configurations are available to optimize the delivery of the required chemicals to prevent or reduce corrosion within a high-pressure pipeline.


To avoid corrosion and equipment damage and enable accurate monitoring, Saf-T-Vise comes with a materials certification and test summary to confirm the product’s materials. These documents improve material traceability to meet the requirements.

Saf-T-Vise atomizers protect operator safety by offering mechanical insertion capability in-high pressure process streams. They can mount in any orientation at various extension lengths up to 20 feet to reach locations that are difficult to access.

The components are tested at safety pressure 1.5x the operating pressure. This validation feature assures compliance with PHMSA regulations and NACE standards, assuring safety while avoiding substantial financial penalties.

Finally, Sentry’s 30 years of experience comes with the Saf-T-Vise brand. This expertise ensures the product you select will work for your needs, and our experts also advise your team on a suitable installation location.
