The Reliance Valves DZR Metering Station (128247) is a professional-grade component designed for HVAC technicians and plumbing engineers who require precise water flow measurement for system commissioning. Its primary benefit is the ability to enable highly accurate flow rate adjustments when paired with manual balancing valves, ensuring optimal hydraulic performance; however, users should note that this device requires specialized pressure-testing equipment to read and interpret its measurements correctly.

It is used to measure the rate of flow in a pipe so that a balancing valve can be adjusted to meet design flow requirements.
While made of DZR brass, its primary design application is for HVAC system balancing and water circulation loops.
Yes, it can be installed in vertical or horizontal lines, provided the test points remain accessible for the pressure gauge.
You will need a portable differential pressure meter or a commissioning computer with compatible test probes.
Yes, there is an arrow cast into the body of the unit indicating the required direction of flow.
Check for air pockets trapped in the pressure sensing lines or verify that the test probe is fully inserted and the seal is intact.
Ensure the test point cap is tightened securely. If it continues to leak, the test point valve core may need replacement.
Verify the differential pressure gauge is calibrated and check the system pump speed against the system design criteria.
Installation: The device should be installed in a straight section of pipe, ideally with the manufacturer's recommended distance of straight pipe upstream and downstream to prevent turbulence that could affect flow readings. Ensure the flow arrow on the valve body aligns with the direction of system water flow.
Compatibility: It is compatible with standard water-based HVAC systems and is designed to work with most portable hydraulic balancing computers and differential pressure manometers.
Care: The station is generally maintenance-free. Periodically inspect the test points to ensure they are free of debris and that the caps are tightened to prevent leaks. If the test points become clogged or damaged, they should be replaced with compatible spares to ensure continued accuracy.
