Plug valves

Robust valves for severe service and demanding media

Plug valves are widely used in applications involving abrasive, corrosive or high-temperature media, where robust construction and reliable sealing are required. Delta Controls specializes in the maintenance, overhaul, modification and production of plug valves for severe service conditions.

Our engineers support plug valves throughout their life cycle, offering both restoration of existing equipment and performance-driven upgrades. By applying reverse engineering and material optimization, we help operators extend service life and reduce total cost of ownership.

Delta Controls is particularly strong in maintaining older and obsolete plug valve designs, where OEM support is limited or no longer available.
