If the max. permissible differential pressures for shut-off are
exceeded for valves from DN 65 to 200, a balanced plug design
is required. In this case the valve must be installed in such a
way that the pressure to be sealed off lies above the valve disc.
The balanced plug works on the bypass principle and can only
serve its purpose if backpressure builds up after opening, so
that the max. permissible differential pressures for shut-off
(see table) are not exceeded.

Butt weld ends to DIN 3239/1 or socket weld ends to
ASME B16.11 and DIN 3239/2 are possible.

Installation instructions
For globe valves with throttling plug, detailed information
about the operating mode is required for optimum valve
selection.
Shut-off globe valves must be installed in the line so as to
ensure that the fluid enters the valve beneath the valve disc
and flows out above the valve disc. They can also be installed
in lines with alternating flow.
