- Warranty: 36 months.
Top priorities of development of new valve models:
-
Extension of lifetime of the gate valve elements (spindle, spool, disk, seat) by use of plasma building-up welding of the working surfaces. E.g., wire 20Х13 is conventionally used for building-up welding of the sealing surfaces of the valve disk and seat (manufactured by OJSC Sibenergomash). But we use electrodes ЦН-6Л, and such metal is 3 times erosion-resistant than wire 20Х13
-
Transition from the casted bodies to the welded bodies that are different in enhanced metal structure, absence of pockets and shells, less metal consumption
-
Development of full-flow bodies for stop valves
-
Enhanced spraying of cooling water due to steam power; increased number of injectors; nozzles with load-dependent alternating flow characteristics
-
Enhanced ergonomics
