Belimo Z2050QPT-D Valve
The Belimo Z2050QPT-D Valve is a 1/2-inch, 2-way Pressure Independent Control Valve (PIQCV) engineered for precision in high-performance hydronic systems. Designed for zone valve applications, this unit utilizes ZoneTight technology to maintain a constant flow of 2 GPM regardless of pressure fluctuations in the loop. The equal percentage flow characteristic is achieved through a specialized stainless steel ball and disc design, ensuring linear heat transfer and preventing "hunting" or overflow in fan coil units and VAV reheat coils. Constructed with a forged brass body and stainless steel trim, the valve supports a wide differential pressure range of 5 to 50 psi and a 360 psi body pressure rating. This HVAC hydronic valve provides a 0% leakage rate, optimizing delta T and significantly reducing pumping energy costs for contractors managing large-scale commercial building automation projects.
Key Benefits:- Pressure Independent Operation: Maintains consistent flow between 5 and 50 psi, eliminating the need for manual balancing valves.
- Zero Leakage Performance: The air-tight shutoff prevents energy waste and ensures precise temperature control in dead-band zones.
- Compact Installation: Small footprint allows for easy integration into tight mechanical spaces, such as radiant panels and duct coils.
- Field Adjustable Flow: Optimized for 2 GPM but compatible with various modulating actuators for tailored system requirement.
- Maintenance-Free Design: Features a self-cleaning stainless steel ball and EPDM O-rings for long-term reliability in water and 60% glycol mixtures.
What is the maximum operating temperature for this valve?
The media temperature range for the Z2050QPT-D is 36°F to 212°F (2°C to 100°C), making it suitable for both chilled and hot water applications.
Does this valve require special tools for actuator mounting?
No, the ZoneTight series is designed for tool-free assembly, allowing the actuator to snap directly onto the valve stem for faster field installation.
Can this valve be installed in any orientation?
It can be installed from upright to horizontal. Installation with the stem pointing downward is not permitted to prevent moisture from entering the actuator.
