MSV-F2 manual presetting valves are used for balancing the flow in heating and cooling installations. The valves have position indicator and stroke limiter as standard. Hood of spindle is integrated with stroke limiter. Setting can be locked. Valve characteristics are set up in measuring device PFM 1000/PFM 100. Valves are free of asbestos. Shut-off function.
The document describes the Danfoss MSV-F2 valve as a manual presetting device designed to balance flow in heating and cooling installations. Key features include an integrated position indicator and stroke limiter, with settings lockable via a nut. The valves are suitable for DN 15-400 sizes and PN 16/25 pressure ratings, operating with water or glycol mixtures up to 130°C (PN 16) or 150°C (PN 25). They are free of asbestos and can be mounted on flow or return pipes.
| Nominal diameter range | DN 15-400 |
|---|---|
| PN 16 Max flow temperature | -10 °C … 130 °C |
| PN 25 Max flow temperature | -10 °C … 150 °C |
| Leakage rate | Grade A; According to ISO5208, Table 5 (No visible leakage) |
| Flow medium | Water and water mixtures with secondary coolants (like glycols) |
| Max. permissible differential pressure | 1.5/2.0 bar |
| Max. permissible flow speed | ≤ 4 m/s |
The maximum flow temperature for PN 16 valves is 130 °C.
The valves have a leakage rate of Grade A, meaning no visible leakage according to ISO5208.
Yes, they are designed for water and water mixtures with secondary coolants like glycols.
