Application
Shut-off valve for water, steam, air, oils, gases
and other non-aggressive fluids. The graph
shows maximum working overpressures and
temperatures. Allowable size of mechanical
impurities is up to 30 µm, volume of
impurities up to 20 g/m3. The valve is not
suitable for flow regulation.
Technical description
The ball valve is a two-way valve, which
closing element is a floating ball sealed by
two seats. The valve has "OPEN - CLOSE"
position stops. The flow is shut off by turning
the lever or wing-handle through 90° to the
right, and for DN 50 - 100 valves by
handwheel via gear box.

horizontal piping.
Operation
The valve can be operated:
DN 50 - by a one-arm lever
DN 80, 100 - by a two-arm lever
DN 150, 200 - by a handwheel operated worm
gear box.
