The Flow Wolf® design was developed by Sealweld to allow the injection of a super heavy sealant compound into severely leaking valves as the manufacturer’s sealant fittings plugged off immediately and subsequent high-pressure at times resulted in the “blow-out” of the check valve mechanism.

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: All valve Lubricant & Sealant fittings shall be Sealweld® Flow Wolf®
