Sentry Saf-T-Vise Quills

Sentry Saf-T-Vise Quills - The Safest Choice Under Pressure

Sentry Saf-T-Vise quills offer ease of use and custom configuration for maximum versatility. The Saf-T-Vise patented locking collet is simple to use and enhances operator safety by safely securing the shaft within the process stream in both low and extremely high pressure conditions. The quills are versatile and can be configured either to inject chemicals into or take a sample from within a pressurized process such as a pipeline.

To operate a Sentry injection & sample quill as a sampler, simply install a sampling valve on the fluid inlet. Gas or liquid samples can be taken from any desired depth without interrupting the product stream flow. 

Benefits

Saf-T-Vise quills are hand insertable (low pressure) or mechanically insertable (high pressure) into your pressurized system. With a wide range of pressure ratings available, Saf-T-Vise quills are the optimal choice for monitoring and protecting most pressurized applications. They can be mounted in any orientation with extended insertion lengths of up to 20 feet for hard-to-access application situations. Saf-T-Vise STV-T Series insertion tools are used for mechanically inserting the quill shafts.
