Pasgemaakte vlinderkleppe
From stainless steel and ductile iron to PTFE-lined and high-temperature alloys, with options for flanged, sleep, and wafer designs, we provide valves that meet exact material, grootte, and pressure specifications for water, chemies, en olie & gas systems.
Custom-Cast Butterfly Valves
Butterfly valves are critical components in industrial flow systems, often exposed to high pressures, repetitive operation cycles, and corrosive or abrasive media. In such demanding environments, every valve must deliver superior durability, precise dimensional accuracy, and reliable performance to ensure safety, doeltreffendheid, en lang lewensduur.
At DEZE Foundry, we specialize in producing custom-cast butterfly valves engineered to meet the exact requirements of our clients. Leveraging advanced casting technologies and rigorous quality control, we offer tailored solutions for flanged, sleep, and wafer designs in materials ranging from stainless steel and duplex alloys to PTFE-lined or high-temperature metals.
Our comprehensive capabilities span engineering design, prototipering, gereedskap, presisie giet, bewerking, hittebehandeling, en oppervlakafwerking.
