Product Overview

CSM-61 2" Flow Measurement Valve

Series CSM-61 flow measurement valves are designed for application on low or medium flow rate HVAC units. Their compact size allows for easy installation and use in crowded piping compartments. The CSM-61’s ball-type design, extended throttling range, and large indicator plate, make for highly accurate flow measurement, even in very low flow ranges.

The CSM-61’s positive memory feature is easy to see, access, and operate, facilitating system balancing and flow measurement. These valves are also bi-directional, so there is no chance of installing the valve in the incorrect flow direction.

Series CSM-61 valves provide positive shutoff, eliminating the need for a separate service valve. The solder style CSM’s may be installed without disassembly, saving costly installation time. These valves are also provided with blowout proof stems. Use, misuse, corrosion, or wear will not allow the stem to “blowout,” releasing pressurized hot or chilled water.
