For Example:
When specifying a 25mm (1") electric 264 Series valve
without flow control and with a male thread x 25mm (1") insert,
you would specify:
264-16-04
264-06-03

Note: For optimum sprinkler performance when designing a system,
calculate total friction loss to ensure sufficient downstream pressure.
Flow rates are recommended not to exceed 5 PSI loss.
*Values are listed in Bar. For kPa values, multiply tabular values by
100. For Kg/cm

values, multiply tabular values by 1,02. Flow rates
are recommended not to exceed 0,35 Bar loss
