Belimo B224VSAFBUP-S-X1 Ball Valve Actuator

Belimo B224VSAFBUP-S-X1 Ball Valve Actuator is a pre-assembled 1-inch, 2‑way valve package that pairs the bronze-bodied B224VS ball valve with a spring‑return AFBUP‑S‑X1 actuator for reliable on/off control in HVAC water systems. The valve features a 1" DN 25 nominal size with a stainless steel ball and stem and female NPT connections, delivering a Cv of 43 and a close‑off rating up to 200 psi, with a maximum rotation of 95° and a motor running time around 75 seconds for a 90° travel. The integrated actuator accepts AC 24–240 V or DC 24–125 V input, providing a spring‑return, on/off operation and two SPDT auxiliary switches rated up to 7 A at 250 VAC, with one switch fixed at approximately 5° and the other adjustable from about 25° to 85°. Power draw is 7 W during run and 3.5 W in hold, with transformer sizing of roughly 7.5 VA (24 VAC) or higher for higher voltages, and an IP54/NEMA 2 enclosure suitable for indoor HVAC environments. The assembly supports precise valve positioning and rapid actuation (75 s to reach 90°) and includes a manual override via a 5 mm hex, making it well suited for retrofits and demanding zone applications in commercial buildings.
