Expanded the standard-size range of commercially available bellows valves KZO 02... according to TU 3742-003-57180370-2005

The range of commercially available bellows valves of the KZO... series according to TU 3742-003-57180370-2005 for military purposes, general industrial design and safety class 4 for nuclear power plants has been increased. Previously, fittings were available in versions KZO 0205... (housing with offset nozzles), KZO 0206... (housing with coaxial nozzles and a duplicate stuffing box), KZO 0207... (housing with an angular arrangement of nozzles), KZO 0208... (housing with coaxial nozzles) with nominal passage diameters up to DN 150 and working pressure up to Pp 10.0 MPa (DN 3...15), up to Pp 6.3 MPa (DN 20...150). Today, the Customer is offered two new valve designs: KZO 0201... (housing with angled nozzles and a duplicate stuffing box) and KZO 0203... (housing with offset nozzles and a duplicate stuffing box). The technical parameters of the entire line have been expanded: nominal passage diameters up to DN 200 (KZO 0206... and KZO 0208...), up to DN 250 (KZO 0201..., KZO 0203..., KZO 0205... and KZO 0207...); operating pressures are: up to Pp 10.0 MPa (DN 3...50), up to Pp 6.3 MPa (DN 65...150) to Pp 4.0 MPa (DN 175, 200, 225, 250). Valves of the KZO... series are a replacement analogue of valves (valves) 14nzh..., 14c..., 15nzh..., 15c..., U26161 and today already surpasses them in many parameters and nomenclature. A distinctive characteristic of KZO valves is the possibility of making the nozzles of the same valve body with different DN or different types of connection (for example: inlet pipe DN 100 – welded connection / outlet pipe DN 80 – flanged connection to the pipeline), which significantly reduces the number of pipeline elements and connections used. To date, the valves of the KZO series... are successfully operated at all operating Russian nuclear power plants, Bushehr NPP, Kudankulam NPP, supplies are underway to the Belarusian NPP, supply contracts have been concluded for the Ruppur NPP. The valves are also widely used in refrigeration and air conditioning systems of submarines and icebreakers, in rocket refueling systems (the working medium is highly concentrated hydrogen peroxide), in systems with highly aggressive media in titanium production (polymer bellows are used) and oil refining, in gas transportation systems in the Far north using high–speed electric drives (replacement solenoid valves), in systems for transporting liquid and gaseous chlorine (a duplicate stuffing box is used), etc. To determine the possibility of using KZO... series valves in new projects, to select analogues to replace existing valves at operational facilities, or to obtain detailed technical specifications, please contact the email address: marketing@okapf.ru
