Description
Belimo Z2075Q-K+CQKB24-RR Overview
The Belimo Z2075Q-K+CQKB24-RR is a factory-assembled, 3/4-inch two-way characterized control valve and electric fail-safe actuator combination engineered for precise hydronic flow control in commercial and light commercial HVAC systems. The valve body (Z2075Q-K) features a characterized ball design that delivers an equal-percentage flow characteristic, ensuring accurate and repeatable control across the full operating range. Paired with the CQKB24-RR actuator operating on 24V AC/DC power, this assembly provides reliable on/off or floating-point control with built-in spring-return fail-safe operation.
