Series LFCSM-61-S Flow Measurement Valves are designed for
application on low or medium flow rate HVAC units and for domes-
tic water recirculation system. Their compact size allows for easy
installation and use in crowded piping compartments. The LFCSM-
61’s ball-type design, extended throttling range, and large indicator
plate, make for accurate flow measurement, even in very low flow
ranges.
The LFCSM-61-S'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 LFCSM-61-S's valves provide positive shutoff, eliminating the
need for a separate service valve. These may be installed without
disassembly, saving costly installation time. These valves are also
provided with blowout resistant stems. The LFCSM-61-S features
Lead Free* construction to comply with Lead Free* installation
requirements.
