Delta V-SEAL

The DeltaV-Seal™ is an all metal, one-piece seal developed to replace Spiral Wound- and Kammprofile-gaskets. It is robust and easy to handle, and its non-resilient metal-to-metal performance obviates the need for re-tightening bolts after installation, and galvanic corrosion is avoided as the DeltaV-Seal™ is in the same material as the flanges.

The standard DeltaV-Seal™ is delivered in several materials as per our customers’ requirements. DeltaV-Seal™ is delivered in ASME ½"– 60" (pressure class up to CL 2500 and EN 1092-1) and DN10 – DN600 standards (pressure class up to PN 400). Key products are in stock.
