ACVATIX™ 6-port control ball valve VWG41.. 6-port control ball valves, PN 16, with externally threaded connection. ● ● ● ● ● ● ● ● ● ● A6V10564480_en--_-G 2020-05-05 Control ball valve body made of hot-pressed brass CW617N DN 10 and DN 20 kvs 0.25...4.25 m3/h Flat sealing, externally threaded connections G..B, per ISO 228-1 Fitting sets ALN..B with external threading per ISO 228-1 Fitting sets ALN..
Use ● ● ● ● ● Used in heated/chilled ceilings as control ball valve. For closed circuit (see Cavitation). Inexpensive: Only one valve with actuator is needed to control a heated and chilled ceiling. Flexible: Various connections can be implemented thanks to external threading. Simple: The brackets, premounted on the actuators, means you can mount them on the ball valves without tools.
Ball characteristic curve DN20 The 6-port control ball valve enables control between two sources through positions 0° and 90°. The 6-port control ball valve is closed at 45°.
Flow diagram DN20 Δpmax = Maximum permissible differential pressure over the ball valve (flow and return), valid for the entire positioning range of the ball valve rotary actuator unit: Δpv100 = Differential pressure over the fully opened ball valve (flow and return) and over the control path at a volume flow V100 V100 = Volume flow through the fully opened ball valve 100 kPa = 1 bar ≈ 10 mWS 1 m3/h = 0.

● Install filter to increase functional security Technical design/mechanical design The Siemens 6-port control ball valve has an internal pressure equalization function that ensures the safe operation of heated and chilled ceilings in a closed valve state (45° position) Changes to media temperature in the heated and chilled ceiling can result in over or under pressure in a closed state and may, under certain circumstances even damage part of the heated and chilled ceiling.
Flow direction Make sure that the valve is mounted in the proper flow direction. Flow direction is indicated on the ball valve body by the symbol on the type label: Commissioning The rotary actuator must be properly mounted before commissioning the 6-port control ball valve. The 6-port control ball valve is delivered in a closed state (middle position). Maintenance The 6-port control ball valve VWG41.. is maintenance free.
Technical data Functional data VWG41.20.. PN class PN 16 Operating pressure 16 bar Maximum differential pressure 2 bar Leakage rate "Air tight" per EN 12266-1, class A Permissible media Chilled water, hot water, water with anti-freeze (max. 50% glycol).
Example: VWG41.20-1.6-2.5 Examples of device combinations Hydraulically balanced solution with 6-port ball valve as changeover and PICV as the control element In this application, the 6-port ball valve changes over between 100% cooling or 100% heating. The PICV valve controls the primary flow for the application.
