3/4" FNPT Adjustable Pressure Regulator, 28-60 PSI

3/4 in.  FNPT Adjustable Pressure Regulator, 28-60 PSI
In Stock

The Drip Store’s 3/4" FNPT adjustable pressure regulators with red cap is used to adjust pressure between 28 to 60 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.

These adjustable pressure regulators are terrific for my microsprayer systems. A typical run of mainline tubing works well around 35PSI. If you have unusually long runs, you can compensate (within reason) by increasing the pressure. I prefer to install the regulator after the canister screen filter so that a partially clogged filter doesn't affect delivery pressure. The unit uses pipe thread, so you'll need the appropriate 3/4" couplers to attach it to your garden faucet.

My typical setup is:

Faucet >> Timer >> Anti-backflow valve >> Screen filter >> Pressure Regulator >> Main line to micro-sprinkler zones >> Self-Drain valve.

Usage took some experimenting because our initial inlet pressure exceeded 110+ psi, which it appeared to disable the functionality. Support at The Drip Store helped me with the problem. Now that spring usage is normal on city water, all pressure valves work fine.

We have a single regulator (ea) on two of our main garden systems, with 5 to 12 watering zones downstream from the valves. There is no problem w/pressure on the far ends of either line. This has saved us valves and extra work. Also, we feel these valves will prevent blowouts we have experienced extensively over the years.

I highly recommend these pressure valves.

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.
