A PSNO Valve ensures that the filter will initiate a backflush cycle with the required pressure for proper cleaning. This is accomplished by maintaining the correct pressure upstream of the valve (downstream of the filter). After the backflush cycle, the filter element(s) will be thoroughly cleaned.With a PSNO Valve, Filters Flush More Efficiently Resulting in: • Less Maintenance • Less Downtime• Less Water and Energy UsedSince the filters flush less frequently and more efficiently, a PSNO Valve is ideal for all types of filters - media or disc. There is no need for a larger pump, saving capitaland operating expenses, to achieve the correct pressure during backflush.PSNO VALVES MAXIMIZE FLUSH CYCLE EFFICIENCYFOR ALL FILTERSPSNO VALVE FEATURESAccurate Stable Control of Upstream Pressure• Changes in flow do not affect the upstream pressure in the valve since the PSNO Valve pilot regulates this pressure Quick Reaction Time of PSNO Valve• Slightly before the filter starts flushing, the PSNO Valve goes into sustaining modefor quick reaction Manual Override on Solenoid for Easy Adjustments• Solenoid settings can be adjusted by simply turning a knob Hydraulic Valve with Direct Sealing Diaphragm • No stem, shaft or bearing within the water passage • Longer life with less maintenance Easy Installation and Low Maintenance• Netafim valves are the most reliable in the industry, resulting in less maintenance • They are easy to install and operatePSNO VALVE OPERATIONA PSNO Valve is always installed downstream of the filter. During standard operation, filtration mode, the PSNO Valve is fully open and flow or pressure to the field is not restricted. The solenoid is not energized at this time (See Figure 1).During the flushing mode, the solenoid is energized and the PSNO Valve partially closes in order to provide the desired pressure to the filter for proper flushing. This is referred to as the sustaining mode. During the sustaining mode, the valve maintains a “set” upstream pressure regardless of flow rate or pressure variations (See Figure 2).At the end of the flush cycle, the solenoid isde-energized and the PSNO Valve will fully open again.Figure 1: PSNO Valve Filtration Mode - valve is fully open and upstream pressure is 30 psi.Figure 2: PSNO Valve Flushing Mode - valve partiallycloses and upstream pressure raises to 40 psi (or any other adjustable set point).Flow Direction PSNO Iron Valve located downstream of a disc filter.NormallyClosedSolenoid3-WayManualSelector(Iron or PVC)4” PSNO PVC ValveControlTubingFingerFilterPRESSURE SUSTAINING NORMALLY OPEN (PSNO) VALVES ▪ 56 ▪ PRESSURE SUSTAINING NORMALLY OPEN (PSNO) VALVESSELECTION GUIDELINESWhen selecting a PSNO Valve, the following recommended flow ranges should be considered to ensure proper sizing and performance.It is recommended not to oversize the PSNO Valve. In relation to the specific flow (GPM), an oversized valve will require the diaphragm to be almost closed in the sustaining mode which can create high velocity, unstable regulation and potential cavitation.MAXIMUMORDERING EXAMPLEPipeline: 6”Required Flow Rate: 500 GPMWith a flow rate higher than 400 GPM, but lower than 600 GPM, a 4” valve is recommended. In this example, even though the pipeline is 6”, a 6” valve is not recommended.Choose the required voltage, Item and Model Numbers from the Ordering Information Charts on the next page.PRESSURE SUSTAINING NORMALLY OPEN (PSNO) VALVES ▪7PVC MATERIAL with SLIP CONNECTION3” PVC also available with threaded connection.IRON MATERIAL with FLANGED CONNECTIONNote: All PSNO Valves are also available with 12VDC and 12VDCL solenoids.

BASIC VALVEThe basic valve consists of four simple parts - body, spring,diaphragm and bonnet - making it the simplest valve to operateand maintain. Installation is quick and easy with its unique inlinedesign which also creates low losses at high flow rates.• Available with two body material options - PVC or Iron• Stainless steel internal spring provides strength and long-life• Flexible reinforced direct sealing rubber diaphragm requires nobearings, guides or internal seals• Cover and body constructed of UV and corrosion resistantmaterialsBasic Valve - PVCBasic Valve - IronPRESSURE SUSTAINING NORMALLY OPEN (PSNO) VALVES ▪ 910 ▪ PRESSURE SUSTAINING NORMALLY OPEN (PSNO) VALVES1. BASIC VALVE, (con’t.)a. DiaphragmPVC and Iron valves are standard with a direct sealing natural rubber diaphragm. All Iron PSNO Valves use a high pressure diaphragm with a standard range of 10 - 230 psi. All PVC PSNO Valves use a low pressure diaphragm with a range of 2 - 60 psi.b. Hydraulic Control Tubing and FittingsHydraulic control tubing is used for various connections on the valve and the tubing size is different based on the valve size and material. Fittings are available in either Plastic or Prestolock Brass based on the valve size and material.*12mm tubing connects the Accelerator Relay of the PSNO Valve to the command filteron the Galaxy Automatic Disc-Kleen Filter.High Pressure DiaphragmHydraulic Control TubingPlastic FittingsPrestolock Brass Fittings2. SOLENOIDA solenoid valve receives an electric command from a controller and converts it into a hydraulic command to the main valve. This enables the opening and closing of the valve by allowing the passage of water into or fromthe control chamber of the main valve.Always use a Normally Closed (NC) Solenoid on all PSNO Valves. Standard solenoid is 24VAC NC. Choose from the following solenoids based on the available power source.All solenoids have a manual override feature. Turning the knob 90 degrees to the left or right will activate the solenoid and place the valve in Sustaining Mode. Latching solenoids have a three position lever for manualoverride. Turning the lever to the right or “O” position activates the solenoid and places the valve in Sustaining Mode. Left or “C” position turns the valve off. For automatic mode, the lever should be placed in the center(locked) position.SOLENOID ORDERING 24VAC Solenoid 12VDC Solenoid 12VDCL SolenoidPRESSURE SUSTAINING NORMALLY OPEN (PSNO) VALVES ▪ 113. PILOTA pilot is a mini-valve which ensures accuracy of the regulated pressure for hydraulic control valves. In PSNO valves, when the line pressure is lower than the pilot’s spring setting (the set point), the pilot permits the passage of water into the chamber of the main valve, partially closing the valve. PSNO Valves are standard with a Green Pilot Spring and a recommended set point of 45 psi.Pilot setting recommendations:• Automatic Disc-Kleen Filters Set the pilot to 40 - 45 psi • Sand Media Filters ................Set the pilot to 30 - 35 psi • Automatic Screen Filters .....Set the pilot to 30 - 35 psiPlastic PilotBronze Pilot4. ACCELERATOR RELAYAn Accelerator Relay is designed with large flow passages to allow faster reaction time of the main PSNO valve. As soon as the solenoid is energized, the relay allows larger amounts of water to flow into the main valve chamber, partially closing the valve. It is a standard component on all 6” and larger valves.ACCELERATOR RELAY Accelerator Relay12 ▪ PRESSURE SUSTAINING NORMALLY OPEN (PSNO) VALVESSETTINGS AND ADJUSTMENT GUIDELINESThe 3-Way selector must be in the A-position. The O-port is used to manually open the valve and the C-port to manually close the valve. A neutral position, not facing any of the ports, locks the water in the bonnet (used in case the pilot malfunctions).INSTALLATION GUIDELINES1. Install the valve downstream of the filter station.2. The arrow on the bonnet should match the flow direction.3. Verify that a finger filter was installed at the upstream pressure port of the valve.4. The valve can be installed in any position. When installing a 6” PVC Valve or a 12” Iron Valve, install the bonnets side by side, not one up and one down. This will allow for easier maintenance.5. For all threaded valves – use five layers of Teflon tape for proper installation.6. For all PVC slip valves – use primer and a heavy duty solvent.7. For all flanged valves – bolts should be tightened in a diagonal sequence.8. For 6” and larger iron valves, the needle valve connects to the 2” command filter on the Galaxy or main filterwith the supplied 12mm tubing. The tee fitting on the command filter will have an open end for attachment to the 12mm tubing from the needle valve.9. Connect the solenoid with the supplied 8mm tubing to the closest solenoid on the filter station by replacing theelbow fitting on the solenoid with a “T” connector.10. Wire the solenoid of the valve to the “M” (master valve) connector on the backflush controller.• For 6” Iron flanged valves and larger:- Open ball valves at the upstream and downstream ports of the valves - Close needle valve and then open it 3 full turns • Start the pump.• Make sure the lines are full and the designed pressure is reached.• Open the main valve manually and perform a backflush cycle with the controller.• The valve remains closed or opens slightly while the upstream pressure maintains a high level.• Loosen the bolt on the pilot until the upstream pressure reaches the minimum required level to backflush the filter.• Wait until the pressure stabilizes, make final adjustments and tighten the lock nut on the pilot.• If the manual override screw on the solenoid was used to manually open the valve in the previous step, turn it to the original position (automatic arrow facing base of the solenoid).• Initiate another backflush cycle from the backflush controller and make sure the valve reaches the set pressure before backflush. Measure the pressure with a pressure gauge. Adjust pre-dwell time in the controller if set pressure is not achieved before backflush.• If pressure is lower than the required set point, tighten the bolt on the pilot; every turn is approximately equivalent to 10 psi. Open the bolt if pressure is higher than set point.MAINTENANCE1. Keep the valve clear from weeds and dirt.2. Turn the handle of the 3-way selector periodically to prevent sticking.3. Verify the upstream pressure periodically, using a quality liquid filled gauge.WINTERIZINGDrain the valve by disconnecting the tubing from the access ports of the valve and at any location where water can be trapped.3” and 4” IRON/PVC VALVE COMPONENTSPRESSURE SUSTAINING NORMALLY OPEN (PSNO) VALVES ▪ 1314 ▪ PRESSURE SUSTAINING NORMALLY OPEN (PSNO) VALVESPRESSURE SUSTAINING NORMALLY OPEN (PSNO) VALVES ▪ 156” PVC VALVE COMPONENTSNotes:• 8mm tubing from the solenoid and 12mm tubing from the accelerator relay, attach to the 2” command filter of the main filter.• Solenoid ports may be labeled either P and A or 2 and 1.16 ▪ PRESSURE SUSTAINING NORMALLY OPEN (PSNO) VALVESPRESSURE SUSTAINING NORMALLY OPEN (PSNO) VALVES ▪ 176” IRON AND LARGER VALVE COMPONENTSNotes:• Solenoid ports may be labeled either P and A or 2 and 1.• 8mm tubing from the solenoid attaches upstream of the valve.• of the main filter.18 ▪ PRESSURE SUSTAINING NORMALLY OPEN (PSNO) VALVESPRESSURE SUSTAINING NORMALLY OPEN (PSNO) VALVES ▪ 19NETAFIM USA5470 E.
