Senninger Pressure Regulator 25 PSI 3/4" Hose Thread Drip Irrigation Pressure Reducer Low Flow Valve - Landscape Grade High Performance White

Please note: Irrigation pressure regulators need outflow and back pressure to regulate the pressure within your irrigation system. With no water flowing through the regulator, the inlet and outlet pressures will measure the same. To verify the pressure maintained in your system, you will need to place a pressure gauge at the end of one of the zones. Turn the zone on, let it pressurize, and once the lines have filled and emitters begin to flow then take the reading. This will reflect the working pressure within your system. 3/4" FHT X 3/4" MHT Senninger Pressure Regulator. Regulates the pressure within the drip irrigation system. Use with other garden hose thread fittings. Choose the appropriate preset PSI rating for your application (normally 25 PSI for poly tubing and 10 PSI for drip tape). The pressure regulator shall maintain the predetermined operating pressure provided the inlet pressure is at least 5 PSI above the expected outlet pressure, but must not exceed the maximum inlet pressure rating. Always install pressure regulators downstream from all shut-off valves. Be sure to install pressure regulators in the proper direction. The arrow on the housing shows the direction of the flow and should always point downstream toward emitters.Features:Low hysteresis and friction lossCan be Installed above or below groundLarge flow path resists pluggingNo external metal parts to corrode Special note: This pressure regulator is not designed to operate under static (constant) pressure. It must be installed after any valves or timers to operate correctly. Using this item under static pressure will eventually weaken the internal spring and cause the regulator to fail.

• Ideal for installations requiring lower flows such as solid set, drip line, soaker hose and other low pressure agriculture, residential and commercial irrigation. This PRLG (Pressure Regulator Landscape Grade) maintains a constant outlet pressure of 25 PSI (1.72 bar) with a flow range between 0.5 - 7 GPM (114 - 1590 L/hr)..
• 100% water tested for accuracy. Senninger pressure regulators are built to rigorous quality standards and are known worldwide for their reliable performance..
• Proper use of this low flow water regulator maintains sprinkler or droplet flow, distribution uniformity, and the overall efficiency of an irrigation system. It also helps conserve water and energy and extend sprinkler and drip system life in your garden or nursery. Works with any standard 3/4" outdoor faucet, hose bib, garden hose, water hose, sprinkler manifold, garden soaker hose or home irrigation system..
• Made in the USA of engineering-grade thermoplastics. This sturdy inline plastic water regulator can be installed above or below ground. No external metal parts for excellent corrosion resistance..
• Important note: This irrigation pressure regulator regulates dynamic water pressure (the pressure while water is flowing). If measuring this regulator with a pressure gauge, do not screw the gauge directly onto the end of the regulator. This blocks the flow of water and measures static pressure, not dynamic pressure. To measure dynamic water pressure, attach a gauge at the end of your irrigation tubing line, or use an inline gauge that allows water to flow unblocked through the regulator..
