Premium design of stop valves

We offer premium desig
of stop valves.

Quick-release valve seats;
Valve stem and seat are made of steel 12Х18Н10Т and reinforced with electrolytic plasma polishing, implantation of nitrogen ions, multilayer ionic and plasma coating with titanium nitride;
Threaded spindle bush — straight bronze БрОФ10-1 (enhances service life);
Warranty: 36 months.

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
