OEM Custom Ball Valves
From precision-cast stainless steel and carbon steel to duplex, super duplex, slitiny niklu, and corrosion-resistant bronze, we deliver OEM custom ball valves engineered for exact material, dimenze, tlaková třída, and sealing requirements.
Custom-Cast Ball Valves
Ball valves operate in some of the most demanding flow-control environments—handling high pressures, rapid cycling, abrazivní kaše, Korozivní chemikálie, and critical shutoff duties.
Na Slévárna DEZE, we specialize in manufacturing custom-cast ball valves designed precisely to customer specifications. Using advanced metallurgical processes and strict quality assurance, we deliver engineered solutions for floating, na čepu, dvoudílný, and three-piece ball valve configurations. Material options include carbon steel, nerezové oceli, duplex/super duplex alloys, nickel-based metals (Monel, Inconel), hliníkový bronz, and other high-performance casting grades tailored for corrosive or high-temperature service.
Our end-to-end capabilities cover engineering design, 3D prototyping, dedicated tooling development, Přesné obsazení, CNC obrábění, tepelné zpracování, povrchová úprava, pressure testing, and full certification, ensuring each custom-cast ball valve meets the highest standards of accuracy and durability.
