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.
