Resideo V9406 Braukmann Verafix-cool User Guide

resideo V9406 Braukmann Verafix-Cool

APPLICATION

V9406 Verafix-Cool control and measuring valves are preferably installed in the return of heat exchangers, for example fan coil units or chilled ceilings. They regulate the room temperature by controlling the flow in connection with an actuator.
With the V9406 Verafix-Cool the flow can either be preset according to the diagram on page 6 or, in combination with a measuring instrument, by flow measurement.

SPECIAL FEATURES

• Flow measuring and presetting on one valve at the same time
• Six functions in one valve: control, presetting, shut-off, measuring, draining and filling
• Compact design
• Suitable for operating pressures up to 16 bar
• Robust, low-noise and flow-efficient valve housing made of corrosion-resistant red bronze

CONSTRUCTION

Overview		Components	Materials
	1	Presentable control insert with protection cap	White plastic
	2	Valve housing PN16, DN15 with 3/4″ flat sealing external threads to DIN/ISO 228. Suitable pipe connections see ‘Accessories’	Red bronze
		Not depicted components:

		Union-nuts and sealings	Brass with EPDM sealing rings
		Valve insert	Brass with EPDM O-rings and soft seals

METHOD OF OPERATION

The V9406 Verafix-Cool is installed in the return of a heat exchanger and controlled by an actuator. The actuator acts onto the spindle of the control insert and in this way regulates the flow through the valve. In a cooling application the actuator closes the valve when the room temperature drops and opens the valve when the room temperature rises. The V9406 Verafix-Cool can also be used for heating applications, in this case operation is the other way round.
Without mounted actuator the valve is normally open. The maximal flow rate can be throttled by presetting the control insert. Presetting is either done according to the flow diagram on page 6 or by flow measurement. A measuring instrument can be connected to the valve by using the V9406 Verafix-MES adapter (accessory). Presetting and flow measurement can be done at the same time. The effect of a changed presetting is immediately displayed by the measuring instrument.
The V9406 Verafix-Cool can optionally be installed in the supply. In that case the draining function isn’t available for the connected heat exchanger as the part of the system before the V9406 Verafix-Cool is drained.

Suitable Actuators

• M6410/M7410 with 180N

Marking

• MNG, DN15 and flow arrow on front
• MNG, PN16 and flow arrow on back
• White manual adjustment cap on top
• Brass nickel-plated protection cap with 19 mm hexagon on bottom

INSTALLATION GUIDELINES

Installation Example

Fig. 1 Regulation of chilled ceilings: a V9406 Verafix-Cool is fitted in the return pipe of chilled ceiling systems.

Fig. 2 Due to the high kvs-value, a single V9406 Verafix-Cool can be used to control several ceiling elements connected in parallel.

Shut-off

Use protection cap for longer-term shut-off
