ACVATIX™ 2-port and 3-port control ball valves, PN 40, with externally threaded connection VAG61.., VBG61.. For use in heating, ventilation, and air conditioning plants as control or shutoff valve. In closed circuits. • • • • • • • • Ball valve body made of brass CW602N (DZR) DN 15...50 kvs 1...63 m3/h Flat sealing, externally threaded connections G..B, as per ISO 228-1 Fitting sets ALG.. with threaded connection Rotational angle 90° Can be combined with electromotoric rotary actuators GQD..9A, GMA..9E..
Features • • • Moderately price: Optimized flow rates mean smaller ball valves can be selected. Low torque means you can combine them with small, less expensive rotary actuators. Long life expectancy: Maintenance-free construction, also thanks to low friction stem and polished ball made of chrome-plated DZR brass. Simple mounting: The brackets, premounted on the actuators, means you can mount them on the ball valves without tools.

Cavitation Cavitation increases wear and tear of the ball and seat and results in unwanted noise. Cavitation can be prevented by not exceeding the differential pressures as per the flow diagram and maintaining the static pressures depicted below.

Applications with auxiliary functions A standard actuator with corresponding functionality can be used if a ball valve application requires a rotary actuator with auxiliary functions (e.g. auxiliary switch or potentiometer). In this case, mounting kit ASK77.x is required in addition to the rotary actuator. Follow the mounting instructions when mounting. Rotary actuator Options Order text: Mounting kit GMA..1E Potentiometer, auxiliary switch ASK77.2 Accessory Kit BV for GMAxx1.
Engineering We recommend installing the ball valve with spring return since temperatures are lower on heating plants which increases the lifespan of the sealing gland on the stem. Ensure there is no cavitation (see Section Technical design [➙ 2]). A filter must be installed upstream of the ball valve to increase functional safety. We recommend using temperature adapter ALJ100 in locations exposed to condensation to protect the actuator.
Mounting It is easy to assemble the ball valve and rotary actuator; it can be done at the construction site. No special tools or settings required. Ball valve VAG61.. / VBG61.. is supplied together with mounting instructions M4212 (7431909220). Mounting position VAG61.. VBG61.. Pipe connection Avoid leakage: • Install fittings as per ISO 7-1. Ball valves (internal threading) = "Rp"; Piping (external threading) = "R". • Do not use too much hemp or PTFE tape. • Do not tighten pipe threading to the very end.
