Steel Valve with Air-Vent for Convectors in Two-Pipe Heating Systems

Application	The steel valve is designed for welding into
	convectors by the manufacturer. The com-
	plete valve consists of a steel valve body, an
	air-vent and a valve insert with integrated
	presetting of max. flow through the con-
	vector. The insert has connection for all
	Danfoss RA 2000 thermostatic sensors.
	The flow capacity of this valve is designed
	for conventional two-pipe heating systems.

1)kv-values indicate the flow volume (Q) in m3/h at a pressure loss (∆p) across the valve of 1 bar.

kv = Q / √∆p. At setting N, the kv-value in accordance with EN 215 can be stated as Xp = 2 K. At lower preset values, Xp will be reduced until approximately Xp 0.5 at presetting 1. The table shows the aver-

age measured values for integrated valves with radiator. The kvs-values indicate the valve capacity, when the valve is fully open.

2)The technical differential pressure indicates the upper limit for a proper valve function. In most twopipe systems the recommended differential pressure is sufficient. In order to achieve a noiseless function we recommend in smaller systems to apply automatic bypass valves or automatic balancing valves. If pump differential pressure exceeds the recommended max. valve differential pressure it is recommended that an automatic balancing valve type ASV-P/PV is added to the system.

Presetting

Materials in contact with water

The presetting values of the integrated valves can be adjusted easily and accurately without the use of tools (factory setting: ‘N’):

▪Remove the protective cap or the thermostatic sensor

▪Find the reference mark

▪Turn the setting ring until the desired presetting number aligns with the reference mark.

Presetting can be selected within the range of 1 to 7. At setting ‘N’ the valve is fully open. Setting in the shaded areas of the drawing should be avoided.

Setting ‘N’ is used when flushing the system.

When the thermostatic sensor is fitted, the presetting is hidden and thus protected against unintended alteration.

To avoid calcification and corrosion, it is important for the composition of the circulating water to comply with the VDI 2035 guidelines.
