Belimo 206-AF3 Torque Limiter 200 Series

Belimo G332B-M+SVB24-SR is a 1-1/4 in (32 mm), three‑way globe valve with bronze trim designed for mixing or diverting chilled or hot water in HVAC and building automation systems. It features female NPT ends, ANSI Class 250 rating, and a Cv of 20 to enable precise flow control in hydronic circuits, including glycol mixtures up to 60%. The bronze‑body valve houses a stainless‑steel stem and EPDM seating and is rated for water service from -7°C to 138°C (20°F to 280°F) with a maximum differential pressure of 35 psi (241 kPa). Coupled with a 24 V electric actuator, the assembly is non‑spring return and modulating, accepting a 2–10 VDC control signal and delivering up to 340 lbf of actuation force. The design supports two flow configurations: A–AB (mixing) with Modified Equal Percentage characteristics and B–AB (diverting) with Linear flow, making it versatile for zone control in two‑pipe or multi‑branch systems. Weighing about 3.7 lb, the unit includes 3 ft of 18 AWG appliance cable with a 1/2 in NPT conduit connection for straightforward installation. This compact, bronze‑trimmed 3‑way valve from Belimo provides reliable, modulating control in hydronic heating and cooling applications, delivering precise Cv 20 performance and a robust, serviceable assembly suited to demanding HVAC control schemes.
