Editorial Review Medium Flow Pressure-Master Regulator is ideal for installations requiring mid-range flows including solid set, drip or other low volume irrigation as well as center pivot and other mechanical-move systems. Each regulator maintains a constant preset outlet pressure based on its flow / inlet pressure. (Note: With no flow through the regulator, the inlet and outlet pressures will be the same.) For best results, use a drip valve assembly at your main sprinkler manifold or water source. You can build your own or get a handy pre-assembled model that includes valve, filter, regulator and drip system adapter. The picture below shows you how it all works. The Y-filter cap is easily removed for filter screen cleaning or replacement.
