Series CSM-61
Flow Measurement Valves
Sizes: 1⁄2" – 3" (15 – 80mm)
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.
Features
• Accurate flow measurement
• Easy to use memory
• Bi-directional flow
• Positive shutoff
• Safe “blowout” proof design
• Available with threaded and solder end connections
• Integral drain port
Applications
• Fan coil units
• Water source heat pumps
• Reheat coils
• Panel coils
• Small branch lines
• Unit heaters
• Unit ventilators
• Finned radiation
• Small domestic hot water lines
• Convectors
• Small pumps
Specifications
A flow measurement valve shall be installed on each hot/chilled
water unit or as otherwise shown on plans. The valve shall be of
the bi-directional, blow-out resistant, tight shutoff, ball design, with
position indicator, memory device, checked metering ports with
drip caps and integral drain ports opposite the metering ports.
The valve shall be a Watts Regulator Company Series CSM-61.

Installation
Generally locate the valve five pipe diameters downstream from
a fitting with two diameters downstream from the balancing
valve free from fittings. If a balancing valve is located downstream from a circulation pump, allow a distance of ten (10)
diameters between the pump and balancing valves.
