Features and Benefits
change (through further addition of heat pumps, for example) each individual flow control valve
will automatically adjust to the new system conditions.
In variable water volume applications, there can be large variations in the system water pressure.
These pressure changes can adversely affect the system balance and heat pump operation. A self
balancing hose kit can provide continuous balancing in this application because of its ability to
automatically adjust to the varying system conditions.
Advantages
• Flow accuracy of ±10%
• Broader application in variable water volume pumping systems
• Greater flow accuracy results in operation closest to design, with least tenant complaints
• Only one pressure differential range of 2 to 80 psid

• Labor savings during balancing can offset increased material cost
• Same or less cost as manual balancing hose kits on smaller diameter hose kits
Disadvantages
• Greater first cost over other manual balancing methods
Automatic flow control hose kit is equipped with:
• Stainless Steel braided hoses with brass end fittings containing fiber washers
• Bronze manual shut-off valves with brass ball with P/T port on supply side
• Brass self-balancing valve
• Optional electronic isolation valve for variable water volume control
• BronzeY-ball strainer with brass cap and stainless steel mesh screen (includes a blow down
valve and hose connector).

At low differential pressure the flow area required to achieve higher flow can exceed the flow area available for the respective series.
Therefore, the minimum pressure differential requirement is increased for the higher flow ranges of each series Mesurflo valve.
