Belimo Z2050QS-J Valve
The Belimo Z2050QS-J is a high-performance 1/2" 2-way ZoneTight zone valve engineered for precise hydronic control in commercial and residential HVAC systems. Featuring a 5.9 Cv rating and sweat connections, this valve utilizes a pressure independent design logic within its specialized ball valve architecture to ensure consistent flow despite pressure fluctuations. The low-torque brushless DC motor provides reliable actuation with minimal power consumption, while the zero-leakage ball design prevents energy loss common in traditional globe valves. For contractors, the field-replaceable actuator and snap-on assembly streamline installation in tight mechanical closets. This valve is optimized for hot water and chilled water applications, offering a high close-off pressure rating to prevent lift-off in high-head scenarios. Its forged brass body and chrome-plated brass ball ensure long-term durability against scaling and corrosion in closed-loop systems.
Key Benefits:
- Zero leakage (bubble-tight) design prevents ghost heating and cooling, improving overall system EER/COP.
- High 5.9 Cv flow capacity provides lower pressure drops across the coil for better pump efficiency.
- Compact sweat connections allow for traditional brazing methods in localized zone piping.
- Field-replaceable actuator ensures easy maintenance without needing to drain the entire hydronic loop.
- Self-cleaning ball technology reduces the risk of sticking due to debris or poor water quality.
Common Questions:
What is the maximum differential pressure for the Z2050QS-J?
This valve is designed to handle high close-off pressures, typically rated for 40-75 psi depending on the specific actuator torque, ensuring it stays shut against high-head pumps.
Can this valve be mounted in any orientation?
The valve can be mounted in horizontal or vertical piping. However, it is standard practice to avoid mounting the actuator below the horizontal plane to prevent moisture buildup in the electronics.
Is this compatible with glycol-based systems?
Yes, the Belimo Z2050QS-J is compatible with up to 60% glycol concentrations, making it suitable for chilled water loops and freeze-protection applications.
