WATTS® regulators Series LFCSM-61-S flow measurement valves are designed for application on low or medium flow rate HVAC units and for domestic 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 shut-off, 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.
