Taco ACUF-125-AC - Accu-Flo Balancing Valve - 1-1/4" Sweat

The Taco Accu-Flo Balancing Valve with a bronze body and sweat connections delivers precision flow control for hydronic systems in a compact, easy-to-service design. Ideal for HVAC and plumbing applications requiring consistent, accurate flow balancing, this valve uses a modified Venturi design to measure flow independently of stem and ball position.

Unlike conventional variable orifice valves, the Accu-Flo offers four to five times greater accuracy, supports low flow readings, and features a tamper-resistant memory stop for quick resets. Its compact construction and calibrated nameplate make it an excellent choice for commercial and residential hydronic balancing.
