Floating valve ball

stainless steeltrunnion

We manufacture all components that are part of ball valves. Therefore, we can adjust the sealing of each kit and adapt it to your specific needs. We produce ball type valves both in soft seat and metal-metal seat. Typology: We machine FLOATING and TRUNNION balls for different types of valves: welded, top entry, end entry and split entry. High Velocity Oxygen Fuel (HVOF) COATING. Through this process we increase the durability and improve the performance of the balls. This technique is used for valves working in high pressure environments and extreme temperatures. They are ideal for corrosive environments or when there are solid particles that can damage soft seats. We apply different thicknesses, from120 µm to 400 µm, according to the client’s needs, providing a hardness of 900 to 1200 HV Size: ½” to 24”. Materials: Stainless steel: F310, F-316, F316L, F316Ti, F-347H, F-304, 410 Duplex and super duplex: F51, F53, F55 TITANIUM: GRADE 2, 3, 5, 7, 12 NICKEL ALLOYS: GR 660, ALLOY 20, ALLOY 400, ALLOY 500, ALLOY 600, ALLOY 718, ALLOY 825 STEEL: A105, LF2, F22, F60, F65 We guarantee: Ball roundness on sealing of 0.02 mm Surface roughness of the sphere of Ra 0.2 (after machining) Roughness after TC coating from Ra 0.1 All our pieces undergo the Blue dye test and alcohol test to guarantee a perfect seal.
