Field of application / operating principle
Shut-off valves are used to shut off and / or restrict the flow of media. Fit the shut-off
valves in such a way that the spindle is vertical and the flow medium enters beneath
the cone. Turning the handwheel opens or closes the shut-off valves (see handwheel
OPEN and CLOSED).
Refer to the manufacturer's data sheets for details on the scope of application of the
individual versions. When used for oxygen as a medium, the operating temperature
of 60°C and the operating pressure of 40 bar must not be exceeded. For acetylene
applications, check the suitability of the materials or consult the manufacturer.
Position indicator
The position of the drive (stroke position) can be determined using the yellow visual
indicator (pos. 6). If the yellow visual indicator is visible, then the valve is open (A). If
the visual indicator is black, then the valve is closed (B). The OPEN / CLOSED visual
indicator settings are configured at the factory, but can also be adjusted or changed
entirely. To do this, open the two screws (pos. 7) slightly, turn the lower section up
or down using the central thread / extension tube (pos. 4) and tighten the screws
again (SW3).
