Automatic Flow Control/Balancing Valve

Ship Building Benefits  
   
The "MESURFLO" automatically delivers the one rate of specified and desired flow to an air conditioning unit coil or exchanger.
The "MESURFLO" does away with the necessity of rebalancing the system when additions or modification of air conditioning requirements occur.
   
The "MESURFLO" eliminates days or weeks of labor for final adjustment to balance the system by progressive modulation of manually operated valves and flow reading devices.
The "MESURFLO" prevents personnel tampering or unauthorized adjustments at sea; thereby maintaining delicate control equipment in battle ready condition
   
The "MESURFLO" permits remaining zones or exchanger units to function normally if other units of the system become inactivated due to battle damage.
The "MESURFLO" contributes to reduction of Product Costs, Product Weight and Labor Costs

 
Operational Information
   

 
As the fluid flows in the direction of the arrows it must pass through the accurately proportioned areas between the Mesurflo Diaphragm and the Mesurflo Seat.  At the lowest pressure which will establish rated flow for a given Mesurflo, the diaphragm is still in its original shape.  As the fluid pressure increases, the diaphragm is squeezed into a new shape.  this new shape combines with the contour of the seat washer to give less are for fluid flow. 

The reduction in area is so proportioned to the increase in pressure that the net result is exactly the the same fluid flow as existed before the pressure increase.  The physical shape of the Mesurflo seat and the diaphragm are quite intricate to give this relationship.  Both the flexing properties of the diaphragm and the dimensions of the contours are rigidly controlled to give the desired flow rate control accuracy.

For small increments of flow rates the seat contour is changed as needed.  For very large flow rates, several Mesurflo Controls are placed in parallel inside a single housing.
