Comments:
Valves with stainless steel body
Ball valves on the drainage pipeline DN25÷DN100.
Hmin=0.5×(Dz1+Dz)+70 [mm].
L2=1000+Dz1+A [mm].
A – determine from the heating network design.
Recommended A for main pipe diameters:
DN32÷DN150 A≥140 mm,
DN200÷DN700 A≥200 mm.
Other diameters on request.
Main pipeline 1.5 m long.
For longer drainage systems, a tee should be used together with a pre-insulated pipe with a service valve.
Diameters and wall thicknesses not included in the table – on request.
