Pressure regulators reduce the incoming pressure entering your system to the recommended operating pressure of the drip/micro sprinkler or soaker hose system.

Without the pressure regulator, the drip irrigation system may have leaks or connections may fail. The ends are garden hose threads with Female thread on the inlet with rubber washer and Male thread on the outlet. If using a timer, regulators should be installed after the timer, as they should not be under constant pressure.

Direct acting pressure regulators are specifically designed for use where accurate and reliable control of line pressure is required, regardless of fluctuations in upstream pressure and/or flow. The use of a rolling diaphragm completely separates the spring assembly from dirt or contaminants in the flow stream and provides long trouble free service while ensuring immediate response to flow and pressure variations. 

The caps on these (white or red) need to be removed to adjust flow.
