Have you ever installed a micro irrigation system for a home garden and turned it on and found the parts blow off causing leaks and damages. Chances are you have installed a system on a high pressure mains supply that has a small flow rate without a pressure regulator.
With micro irrigation systems it is best to install a preset pressure regulator that provides a constant downstream pressure over its recommended flow range.
When selecting a pressure regulator you need to consider the flow range that the regulator operates within as well as the pressure regulation rate. Your micro irrigation system should be delivering a flow within this zone.
Example: Our pressure regulators work with a flow of between 24 lph (6 x 4 lph drippers) to 1800 lph (450 x 4 lph drippers).
The pressure regulator is best installed at the start of the system so that it protects all the low pressure micro irrigation components. They are commonly installed direct to:
- a garden tap or manual valve (either on the tap or after a tap timer)
- the outlet of automatic solenoid valve
