Introduction Choosing the best flow control balancing device for water-source heat pump equipment just got easier. Superior circuit balancing of the HVAC equipment is an important aspect to the overall layout and design of the HVAC system. Proper balance of the system can protect the HVAC equipment, while providing a longer equipment life. Superior circuit balancing can save energy by supplying the proper amount of fluid to make your system perform at its highest efficiency.

Features and Benefits Manual Flow Control Ball Valve Flow Control Traditionally, the first choice in a balancing device on a water-source heat pump application is the lowest first cost option. In water-source heat pump fluid flow balancing, this typically employs a manual balancing (ball valve) device with hoses.
Features and Benefits (1) Optional electronic isolation valve for variable water volume control. (1) OptionalY-ball strainer with brass cap and stainless steel mesh screen (includes blow down valve and hose connector). Table 1.

Features and Benefits (1) Bronze manual valve includes memory stop positive shut-off and dual P/T ports. (1) Optional electronic isolation valve for variable water volume control. (1) OptionalY-ball strainer with brass cap and stainless steel mesh screen (includes blow down valve and hose connector).
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.

Features and Benefits There are three features that every self-balancing valve should possess to accomplish the job of automatically balancing an HVAC system in the industry.The valve should be: • Non Clogging • Quiet • Accurate Non-Clogging. The live flexing action of the elastomeric diaphragm against the orifice seat permits passage of reasonably sized particles of sludge, rust balls, thread chips, and other debris. Because the working parts are of a two piece design, they are resistant to fouling.
Features and Benefits The automatic flow control valve is factory set to a rated flow, and shall automatically control the flow to within 10% of the rated value over a 40 to 1 differential pressure, operating range (2 to 80 psid1). Operational temperature is rated 40-200°F.The valve body is constructed from hot forged brass UNS C37700 per ASTM B-283 latest revision. The ball valve is constructed from forged bronze with brass ball construction. It is rated from fluid 40-200°F.
