Automatic balancing valve ASV-P (DN 15-40)

Description

Ordering

ASV balancing valves are designed to guarantee high quality of the automatic balancing by:

- a pressure released cone,

- an adapted membrane for every valve dimension which provide constant quality performance for all sizes.

A 90° angle between all service features (shut-off, draining, measuring) allows an easy access under any installing condition.

ASV valves (DN 15-40) are packaged in styropore (EPS) which can be used for insulation at

ASV-P valves are automatic balancing valves with fixed setting (10 kPa) for creating optimal hydronic balance in residential heating systems.

The setting can be increased to 20 or 30 kPa by spring replacement. Spring can be replaced under pressure.

temperatures up to 80 °C. An insulation cap is available as an accessory for insulation at higher temperatures (up to 120 °C).

ASV-P valves are to be mounted in return pipe, in combination with partner valves mounted in f low pipe. As a partner valve ASV-M/I/BD are recommended.

ASV-P balancing valve, inclusive in the box: 1.5 m impulse tube (G ⁄ A) and drain cock (G ⁄ A) Constant differential pressure 10 kPa ; can be upgraded to 20 or 30 kPa setting respectively

There are two basic configurations when using ASV partner valves (ASV-BD, ASV-I, ASV-M, MSV-F2):

- partner valve outside the control loop (Fig. 1). Recommended configuration: it results in best performance since whole controlled pressure range is available to the riser. Flow limitation is done on each terminal unit in the riser (for example, RA-N with presetting on radiator,

- partner valve inside control loop (Fig. 2). Offers flow limitation on the riser however part of the controlled pressure range is used by pressure drop on partner valve (p recommended when flow limitation on each

etc).

Fig. 1 Setting of ASV-P = Δpriser Fig. 2 Setting of ASV-P = ∆priser + ∆p

ASV-BD can be used outside or inside control loop by choice of which measuring nipple is open. To be used outside control loop, blue measuring nipple needs to be open. In this position, flow verification can be done (default position). To be used inside control loop, red measuring nipple needs to be open. In this position, flow verification & flow verification can be done.
