Note:

The minimum flow rate while in continuous use should be more than 10% of the maximum flow rate.

The model No. of low differential pressure type valves is followed by "L". (e.g. UFS-200L)

The E dimension is the minimum dimension when there is a concrete ceiling with no opening above the valves, and is a dimension that takes into consideration the winch device for valve bores of 350mm or more.

We also manufacture valves with other specifications not listed above upon request. Please inquire.



Specifications stated here may be subject to change without notice due to product improvement.
