V2476 Verafix-VKE

PRE-SETTABLE H-BLOCK FOR COMPACT RADIATORS

PRODUCT DATA

Design

The Verafix-VKE consists of:

•Straight valve body for floor connection or angle valve body for wall connection

•Valve insert

•Nickel-plated brass protection cap

•Radiator connection nuts

•Universal externally threaded connections (Eurotaper connections) suitable for copper, precision steel tube, plastics and composite tube (see accessories for external thread fittings)

Materials

•Matt nickel-plated hot-forged brass body

•Brass valve insert

•EPDM or NBR O-ring sealings

•Brass union connections

•Nickel-plated brass radiator connection nuts

•Nickel-plated brass protection caps with NBR sealings

Application

The verafix-VKE is an adjustable lockshield valve for compact radiators with connection centres of 50 mm. It is used on twopipe systems with radiators which have integral valves to regulate and shut-off individual radiators.

Verafix-VKE is suitable for hot water heating systems.

Verafix-VKE 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
Dura	Manaut	Stelrad

Verafix-VKE with 3/4" external threads are suitable for radiators which include the following makes:

Baufa	Buderus	Kermi	Ribe
Brötje	De Longhi	Reusch	RIOPanel
Brugman

Features

•Adjustable by stroke limitation with system in full operation

•Optional flow direction. Performance values apply for both directions of flow.

•Robust brass housing

•Connection on pipework side 3/4"external thread for copper, soft steel, plastic and composite pipes

•Connectors on radiator side 1/2" internal or 3/4" external thread

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.

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.
