The "Gold Standard" For Controlling Water Flow In HVAC Systems
Hays' patented Mesurflo® automatic flow control valves have been called the "Gold Standard" because their unique features and benefits make them the ideal solution for controlling flow in waterbased cooling and heating systems. Unlike other control valves which can be noisy and clog easily, Mesurflo® offers you these significant benefits:
Eliminates oscillation, vibration, noise and feedback in the system Non-clogging design that can be backwashed for easy cleaning Maintains proper flow rate for high efficiency of the coil Reduces the number of valves required to balance the system Eliminates the high cost of testing and balancing Additional devices may be added without affecting the system balance Accuracy provides 99.8% heat transfer
Mesurflo® automatic flow control valves are now available with flow rates up to 9.00 GPM in the small brass body designs. Previously all 9.00 GPM applications required the use of the large brass body designs such as models 2520 and 2524. Now, nearly 90% of 9.00 GPM applications can utilize the small brass body valves, models 2510, 2514, 2516, 2519 and 2517. This is approximately a 50% reduction in brass for 9.0 GPM applications, resulting in substantial cost savings to you.
