XCZ-075 pressure loss data above 5 GPM is with PSI-M30X pressure regulator.
Maximum flow rate with “M” style regulators is 22 GPM.
* For flows below 3 GPM (0,7 m
3
⁄h; 0,11 l/s), always use RBY Series
200 mesh (75-micron) filter installed upstream of valve.
**For flows greater than 5 GPM/300 GPH (1,14 m
3
⁄h; 0,32 l/s; 1.135,50 l/h),
substitute PSI-L30X with a PSI-M30X pressure regulator.
