I have a property with 135 psi. I'm installing mainly MP Rotators. I have to regulate operating pressure to about 30 psi to stay within the percipitation rate I've chosen for the nozzles. The MP Rotator nozzles fluctuate in their percipitation rates based on psi at the nozzle, even though they are called matched percipitation rate nozzles. I was going to install a Hunter ICV valve as a master valve, and then install the Hunter Accu Set Pressure Regulator accessory onto the valve to regulate pressure within the whole system and control water hammer. Has anyone done this before. Thanks.
