PRE-SETTABLE H-BLOCK FOR COMPACT RADIATORS

PRODUCT DATA

Verafix-VK for two-pipe systems

Verafix-VK for one-pipe systems

Design

The H-block valve 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-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

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).

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
