6 Operation
The T118 globe valve serves as a fitting between combined pressure regulator and tank.
With the help of this valve the combined pressure regulator can be replaced without having to empty the
tank.
The following steps are necessary for this.

Depressurise the combined pressure regulator with the globe valves.

Cool down/heat up to ambient temperature, -40 °C to +65 °C.

Loosen (“disconnect”) the 50 mm AF union nut until the main seat is closed.

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 bores in the
union nut.

After pressure relief, dismount the inlet part 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.

Protect the outlet part against ingress of dirt and moisture.

After dismounting, separate the inlet part from the combined pressure regulator.

Clean, free from oil and grease for O
2
application.

Inspect for damage.

NOTICE! Damage to the system possible! DO NOT install a damaged or dirty inlet part!
