Identification
The Verafix-VKE differs from the outwardly identical VerafixVK in the design of the valve inserts. Verafix-VKE inserts
have a hexagon socket for shut-off. (Verafix-VK inserts have
an additional pentagon nut on top. The hexagon socket for
shut-off is accessed by a hole in the middle.)

VERAFIX-VKE
Function
Individual pre-setting of the Verafix-VKE is made with a
commercially available 6 mm Allan key. The flow rate is
adjusted by turning the valve insert from the closed position
to the calculated value. The relationship between the number
of turns and the flow rate can be read off the flow diagram
where ‘open’ refers to the fully open position – valve insert
turned anti-clockwise as far as possible. Pre-setting only
needs to be done on one side either supply or return.
Dimensions
The supply and return of the radiator can be shut-off by
turning the valve inserts fo the Verafix-VKE clockwise to the
closed position with a 6 mm Allan key. Shutting-off the
radiator with the Verafix-VKE causes the pre-setting to be
lost.
Pre-settable Verafix-VKE lockshield valves are supplied set
fully open.
