Automatic Accessible Flow Controls -
Flow Control Valves with Accessible Cartridge
The Griswold Automatic Flow Control Valve is used in many different applications, mostly
in the HVAC industry to maintain balance in a HVAC System. The Automatic Flow Control has
a spring loaded cartridge that dynamically absorbs pressure fluctuations resulting from
changing flow conditions due to varying heating/cooling loads. These fluctuations in
pressure, within a given pressure differential control range, do not change the flow
through the valve, therefore the flow is controlled to within +/- 5% of the designed flow.
Automatic Flow Controls do not require
any additional balancing as do Manual Balancing Valves, therefore they reduce labor costs
from not having to balance and rebalance the valves. Automatic/Accessible means you can
service the valve or exchange the flow control cartridge if your system flow requirements
change, without having to break pipe connections. Simply remove the cap and exchange the
cartridges.
