Balancing Valve Finder

Hydronic balancing valves fall into three groups: manual (static) balancing valves with a presetting scale and measuring points (Danfoss MSV-BD, MSV-F2, USV-I, LENO MSV-B; IMI TA STAD, STAF, STAP), automatic differential-pressure controllers that hold a constant Δp across a riser (ASV-PV with partner valve ASV-M or ASV-I; TA STAP), and pressure-independent balancing and control valves that combine flow limitation with a control valve for an actuator (Danfoss AB-QM in DN 10–250, Frese OPTIMA, TA KTM). Selection is by DN, design flow or Kv, connection (internal or external thread, flanged PN 16/25) and the Δp range of the controller. The finder lists the catalogue by family and DN with the version and connection so a valve of the same function and size can be quoted.

AB-QM valves are sized by the design flow, not by pipe size — a DN 15 valve covers several flow ranges (LF, standard, HF) and must be paired with the matching actuator (TWA-Q, AME, NovoCon). ASV-PV controllers are ordered with the setting range (5–25, 20–40, 35–75 kPa) and used together with the partner valve on the supply. Insulation caps, test plugs and tailpieces are family- and DN-specific.

Coverage: 431 of 431 catalogue rows with a readable size are listed (554 rows in these categories in total; the remainder can be found through the site search by part number).
