Sealweld Valve Fittings and Adapters

The patented Flow Wolf® one-way check valve design has been incorporated into many of our fittings and adapters for increased technician safety and improved pipeline integrity. Extend the in-service life span of all of your critical valves many times over by specifying “Flow Wolf® – No Substitutes” when ordering new valves and during outages when fittings can be safely replaced.

Introdução ao produto

The patented Flow Wolf® design was originally invented in the field by our founder, W.J.

“Bill” Chisholm, on a job where we needed to inject a super heavy sealant compound into

severely leaking valves.

The valve manufacturer’s sealant fittings plugged off immediately and subsequent high-pressure resulted in the “blow-out” of the check valve mechanism.

This situation lead to the development of the Flow Wolf® design with the assistance of Russian field engineers and Sealweld® engineers in Canada.

The Flow Wolf® design is now in use in pipeline valves around the globe and preferred by many of

the world’s largest pipeline operators. This design is also available by special request when you

order new valves from all the world’s leading valve manufacturers. Be sure to specify: “Sealant fittings to be the Sealweld® Flow Wolf® design - no substitutes!”
