3/4 in.  FNPT Adjustable Pressure Regulator, 17-35 PSI
In Stock

The Drip Store’s 3/4" FNPT adjustable pressure regulators with white cap is used to adjust pressure between 17 to 35 PSI. The adjustable pressure regulator is used in applications that demand accurate and reliable control of pressure no matter what fluctuations occur in the supply line pressure or flow rates.

The pressure regulator is a device used to reduce and regulate the water pressure entering your drip or micro sprinkler irrigation system to that recommended for the system. The 3/4" and 1” direct acting pressures regulators are pressure-reducing devices expressly designed for use in line pressure applications. The Drip Store’s line of adjustable pressure regulators is used for residential, commercial and agricultural applications. A diaphragm that responds very quickly to pressure fluctuations in the irrigation system, reducing the higher incoming pressure to a lower and more desired outlet pressure, triggers the adjustable pressure regulator. The pressure regulator's rolling diaphragm provides total separation of the mechanism from the flow for a long lasting trouble-free operation, as well as minimal flow resistance. The high quality & accurate rolling diaphragm w/ stainless steel spring allows for variances in upstream pressure. The adjustable pressure regulator comprises a durable plastic body and stainless steel spring that determines the downstream pressure and can be changed in the field.

Don't over tighten, I broke the regulator in half when I went to give it "an extra half a turn" to line up the piping.

Installation for Adjustable Pressure Regulator

Use the pressure regulator for your irrigation system and install the device after the filter. Choose the correct thread (hose or pipe).  The pressure regulator should never be installed on a main line where the device is under constant pressure. In this situation, we recommend installing the pressure regulator after the valve. 

To adjust the pressure use a screwdriver and turn the screw under the cap: + to raise the pressure and – to lower the pressure.

Note: A common misconception is that turning a valve or faucet down will reduce the downstream pressure, but this is incorrect; turning the water down only reducers the flow, not the pressure. The pressure remains high.
