Product Description
The Verafix-E is a presettable radiator lockshield valve for the return connection of radiators or heat exchangers. It is used:
- in typical two-pipe heating systems
- in special applications in one-pipe heating systems
for shut-off and regulation of individual radiators. Together with a draining adapter (see Accessories) radiators can be drained or filled with the system in operation. The presetting isnt affected by this. Installation in supply also possible, draining/filling function isnt supported. The lockshield valve is suitable for hot water and low pressure steam heating systems and cold water cooling systems.
