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, kahusayan, at mahabang buhay ng serbisyo.

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, lug, 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, prototyping, mga tooling, katumpakan paghahagis, machining, paggamot ng init, at pagtatapos sa ibabaw.
