Project Info

Category:

Do you need a safe and reliable isolation solution for downstream confined space work?

At Flow Control Solutions, we provide advanced isolation methods tailored to your project’s safety and engineering requirements. Our technologies, including line stopping, valve insertion, and nitrogen line freezing, can be deployed as a secondary block in a double block & bleed configuration or engineered as single valve isolations where space or system constraints require it.

The photos shown features a 42″ (1050mm) single valve isolation line stop rated at 230 PSI, designed with a “stepped” pressure zone. This innovative setup provides over a 2X safety factor, meeting the stringent standards for single valve isolation engineering and P.Eng signoff.

Whether you need to isolate for maintenance, repairs, modifications, or confined space entry, our engineered solutions help ensure your work is completed safely, efficiently, and in compliance with industry standards.

If you’d like to explore line stops, valve insertions, or nitrogen ice plugs for your next project, trust Flow Control Solutions to deliver proven, engineered results.
