Description
Belimo Z2050QPT-F — 1/2″ 2-Way Zone Valve Overview
The Belimo Z2050QPT-F is a 1/2″ two-way zone valve engineered for precise hydronic flow control in commercial and residential HVAC systems. Featuring an equal percentage flow characteristic, this valve delivers accurate, proportional flow regulation across its full operating range — ideal for heating and cooling coil applications where tight temperature control is critical. The press-type (PT) quick-connect union ends simplify installation and future serviceability, allowing the valve body to be separated from the piping without disturbing the actuator.
Key Features
- 1/2″ pipe size with press-fit (PT) quick-connect union end connections
- 2-way, equal percentage (=%)) flow characteristic for precise flow modulation
- 5 Cv flow coefficient for optimized system performance
- 50 PSI close-off pressure rating
- Fail-safe (spring return) design ensures the valve returns to a defined position on power loss
- Compatible with Belimo actuators for easy pairing and system integration
- Compact, durable construction suitable for hydronic heating and cooling applications
Application
The Z2050QPT-F is well-suited for use in fan coil units, air handling units, heat exchangers, and terminal unit hydronic systems. The equal percentage characteristic makes it especially effective in variable-flow systems where precise control of heat transfer is required. The fail-safe spring return function provides added reliability and system protection in the event of power interruption.
