Belimo Z2050Q-J Valve Body

The Belimo Z2050Q-J Valve Body is a high-performance 1/2" 2-way zone valve engineered for precision flow control in demanding hydronic systems. Featuring a 5.9 Cv rating, this forged brass valve body is optimized for chilled or hot water applications, including VAV reheat coils, fan coil units, and radiant panels. The chrome-plated brass ball and stem, combined with PTFE seats and EPDM O-rings, ensure a 0% leakage rate and maintain system efficiency across a fluid temperature range of 36°F to 212°F. Designed for commercial HVAC systems, the equal percentage flow characteristic provides linear heat output and stable control even at low loads.

Built for rapid field deployment, the Z2050Q-J supports tool-free snap assembly with compatible CQ series actuators and features NPT female internal threads for standard piping connections. With a 360 psi body pressure rating and a 75 psi close-off pressure, this ZoneTight QCV (Quick Connect Valve) is an essential component for contractors seeking maintenance-free reliability in space-restricted installations.

• Optimized Performance: High 5.9 Cv capacity supports up to 11.8 GPM at a 4 psi differential for high-demand zone heating and cooling.
• Durable Construction: Features a chrome-plated ball and forged brass body for long-term resistance to scaling and corrosion.
• Energy Efficiency: The bubble-tight shut-off eliminates ghost flows and energy waste in idle zones.
• Labor Savings: Integrated snap-fit flange allows for manual actuator mounting without specialized tools.
• System Versatility: Compatible with water or up to 60% glycol solutions, making it ideal for diverse hydronic layouts.

What actuators are compatible with the Z2050Q-J?
This valve body is designed to pair seamlessly with Belimo CQB (non-fail safe) and CQKB (electronic fail-safe) actuators for rapid field configuration.

Can this valve be installed in any orientation?
The Z2050Q-J can be installed in orientations ranging from upright to horizontal. It should not be installed with the stem pointing downward to prevent moisture from entering the actuator.

Is the flow rate adjustable on this specific model?
While the 5.9 Cv is the maximum rating, the flow can be field-adjusted using the end-stop clip on the paired actuator to meet specific design requirements.
