Preinsulated DN25-200 shut-off valves TWIN
The insulation jacket is made as standard HDPE, diffusion barrier, UV PROTECT COLOR. On request, pipes can be delivered in a color jacket compliant with RAL (only with UV PROTECT COLOR).
Notes:
To operate valves with diameters DN25÷DN80 use T-keys, for valves with diameters DN100÷DN150 use a planetary gear.
Valves should be placed in wells or chambers.
Extend the catalog height of the stem of the shut-off valve using extensions for pre-insulation valves by H = 1.0 m, H = 2.0 m.
All extensions can be shortened.
