Product Description
V2440 Veramax lockshields are used at the supply or return of heat exchangers in hydronic cooling and heating systems requiring high flow rates. They have the following functions:
- Shut-off: by closing the valve the flow through the heat exchanger is shut-off
- Presetting: the flow through the heat exchanger can be throttled to meet system requirements
V2440 Veramax lockshields are suitable for hot water or low pressure steam heating systems and cold water cooling systems.
