PRODUCT DATA
Application
The verafix-VK is an adjustable lockshield valve for compact
radiators with connection centres of 50 mm. It is used on twopipe and one-pipe systems with radiators which have integral
valves to regulate and shut off individual radiators. Individual
radiators can be drained or filled with the system in full
operation using a special draining and filling adapter (see
accessories).
Verafix-VK is suitable for hot water heating systems.
Verafix-VK with 1/2" internal threads are suitable for radiators
which include the following makes:
Bemm Finimètal Northor Superia
Concept Ferroli Purmo Thor
Dia-Norm Henrad Radson VEHA
Dia-therm Korado Schäfer Vogel & Noot

VERAFIX-VK
Function
Individual pre-setting of the Verafix-VK is made with a
commercially available 4 mm hexagonal key by turning to the
calculated value. The flow rate is adjusted by turning the
spindle on the regulating valve. The relationship between the
number of turns and the flow rate can be read off the flow
diagram.
Draining or filling can be carried out using the draining
adapter (see accessories).
Dimensions
The supply (or return) of the radiator can be shut off by
turning the spindle on the Verafix-VK to the closed position
with a hexagonal key.
Draining, filling or shutting off the radiator with the Verafix-VK
causes the pre-setting to be lost.
Pre-settable Verafix-VK lockshield valves are supplied set
fully open. The one-/two-pipe version is supplied with the
bypass set fully closed
