MEGA Seal Ball Valves

Ladish Valves MEGA SEAL is our Critical-Service Metal and Graphite Seated Floating Ball Valve line with all of the technical features needed for the more demanding Industrial Applications. Designed for Safety, Low Emissions, Long Service Life, and ease of maintenance, this series is available in Split-Body Full and Reduced Port styles as well as One-Piece (Uni-body) reduced port construction. Available in Exotic Alloys as well as more common materials, the MEGA SEAL should be your go-to choice for Critical and Toxic Services in applications where Elastomeric Seats and Seals are impossible to use or limit system reliability.

METAL SEATING

For Critical services containing solids, including those with high temperatures and pressures, Ladish recommends our Metal-Seated Ball Valve.
