Belimo G220S-K+LVKB24-SR 3/4" 2-Way Globe Valve Assembly 7.5 Cv Electronic Fail-Safe 24V Modulating

The Belimo G220S-K+LVKB24-SR is a factory-assembled 2-way globe valve and electronic fail-safe actuator combination designed for proportional control of HVAC hydronic systems. The assembly pairs the G220S-K 3/4" NPT stainless steel trim globe valve body (ANSI Class 250, Cv 7.5) with the LVKB24-SR modulating, electronic fail-safe linear actuator, delivering a complete, ready-to-install control valve solution.

The LVKB24-SR actuator operates on AC/DC 24V power and accepts a 2–10V DC proportional control signal (compatible with 4–20 mA via optional 500 Ω ZG-R01 resistor). It provides an actuating force of 500 N (115 lbf) and features electronic overload protection throughout the full stroke. The actuator is double-insulated and meets cULus requirements without requiring an electrical ground connection. Protection rating is NEMA 2 / IP54.
