Cleaning
6.1.
The flow chambers
The passages of the valve are cleaned by the cleaning liquid during
cleaning of the connected pipelines.
The compatibility of the individually selected cleaning processes
and liquids with the respectively applied seal material must be
verified.
7. Installation
- The Delta RGMS4 valve must be installed in such a way that
products and cleaning liquids can drain off the valve housing.
Priority should be given to a vertical installation.
Attention!
Observe welding instructions!
Conductive connection to the pipeline must be provided.
The integration into the operational potential equalization must be
guaranteed!

Welding Instructions
RGMS4
- Before welding of the valve, the complete valve insert must be
dismantled from the housing. Careful handling to avoid damage to
the parts is necessary.
-
Dismantle the mating flanges from the valve housing and remove
the flange seals. Just tacking or adjustment of the mating flanges
should be undertaken with fixed valve housing.
- Welding should only be carried out by certified welders (DIN EN ISO
9606-1) (seam quality DIN EN ISO 5817).
- The preparation of the weld seam up to 3 mm thickness shall be
carried out as a square butt joint without air. (Consider shrinkage!)
- TIG orbital welding is best!
-
After welding of the valve housing or of the mating flanges and after
work at the pipelines, the corresponding parts of the installation
and pipelines must be cleaned from welding residues and soiling. If
these cleaning instructions are not observed, welding residues and
dirt particles can settle in the valve and cause damage.
- Any damage resulting from the non-obeservance of these welding
instructions is not subject of our guarantee.
