4.3 Intended application
The T118 globe valve serves as a fitting between combined
pressure regulator and tank.
The T118 globe valve is to be installed in such a way that the
valve is positioned vertically and the medium flowing through it
enters under the main seat.
Loosening (“disconnect”) the 50 mm AF nut causes the main
seat to close and the pipeline on the outlet side is shut off. After
the closing of the main seat, the pressure on the inlet side is
dissipated via two bores in the union nut. Following the pressure
relief, the inlet part can be dismounted together with the
combined pressure regulator.
If the pressure in the pipe on the inlet side exceeds the pressure
on the outlet side by 4.5 bar ±1 bar during the disassembly
between the shut-off and pressure relief functions, the main seat
is opened and the excess pressure is dissipated via the outlet.
