Watts 0856740 Valve
If you are looking for precise hydronic balancing and system diagnostics in a compact package, the Watts 0856740 flow measurement valve is the industry standard for 1" NPT applications. Designed specifically for low-to-medium flow rate HVAC units, the Series CSM-61-M1-T serves as a high-accuracy alternative to standard ball valves by integrating a position indicator and a memory device. This allows a technician to establish a set point once and return to it exactly after shutoff, eliminating guesswork during HVAC system balancing. Built from a rugged bronze body with a high-performance, blowout-proof stem, this valve is engineered to withstand pressures up to 300 psi and temperatures reaching 250°F.
The CSM61M1-T model features bi-directional flow, making it nearly impossible to install incorrectly—a critical time-saver on commercial jobsites. It includes two 1/8" NPT brass pressure taps for direct connection to a differential pressure gauge, enabling real-time flow verification across fan coil units, water source heat pumps, and multi-zone hydronic branches. Because this valve provides positive shutoff, you don't need to install additional service valves, simplifying your piping layout. For HVAC flow measurement that ensures terminal units receive the exact GPM required by design specs, this Watts monitor is the reliable choice for veteran pipefitters.
Key Benefits for the Contractor:- Precise Hydronic Balancing: Large indicator plate and memory screw allow for fine-tuned flow control and repeatable settings.
- Internal Ball Valve Design: Provides bi-directional flow capabilities and reliable positive shutoff functionality.
- Durable Construction: Heavy-duty bronze body and blowout-proof stem designed for non-potable hot and chilled water systems.
- Integrated Monitoring: Pre-installed pressure taps and integral drain ports simplify maintenance and system commissioning.
- Compact Profile: Ideal for tight piping compartments in unit ventilators, finned radiation, and branch lines.
- How do you calculate the flow rate using this valve? Connect a differential pressure meter to the brass pressure taps and compare the PSI drop against the Watts CSM-61 series flow charts.
- Is this valve suitable for domestic drinking water? No, this is a non-lead-free balancing valve designed exclusively for non-potable hydronic HVAC applications.
- Does the valve require special spacing for accuracy? For maximum measurement precision, install the valve in a straight run with 5 pipe diameters upstream and 2 pipe diameters downstream.
