3/4 in. In-Line Sprinkler Valve with Flow Control

A:  Rain Bird offers two in-line sprinkler valves with flow control, 3/4" or 1" (inlet/outlet), depending on the size of your main water line that would connect to the valve. If you would like additional help with product selection, or setting up and operating the valve, please feel free to contact our technical support at 1-800-RAIN BIRD (800-724-6247) and we’d be more than happy to assist.

A:  No, think of this device as an electronic spigot (Open/Close). You CAN attenuate the flow, but you wont be able to create more output pressure than what is inputted.

A:  Hi Prime, We’re assuming you’re inquiring about increasing water pressure because you’re experiencing low water pressure to either your entire sprinkler system or to a specific zone. If that’s the case, the operating pressure of all sprinkler systems is dictated by whatever water pressure (PSI) and number of gallons per minute (GPM) are at the main water supply line. For maximum performance, each zone within your sprinkler system is controlled by a valve and should be set up with the proper amount of sprinklers so that the PSI and GPM capacity of the system is not exceeded. That said, a valve with flow control simply allows you to regulate the amount of water and the pressure in which it flows, passing through the valve itself and to the sprinkler heads on that zone. But again, the maximum water amount and pressure is limited to what’s available from the main water supply. If your pressure is too low, we’d recommend you look at the following possible causes: (1) Pressure drain from washing machines, showers, etc., or a possible broken pipe; (2) Master shutoff valve is not fully open; (3) Blockage in the main supply line; (4) Too many heads on line; redesign system layout to reduce the number of heads operating at once. We hope this helps, and if you have any additional questions, please do not hesitate to reach out to our technical support team at 1-800-RAIN BIRD (800-724-6247) and they’d be more than happy to assist.

A:  They are a diaphragm pilot operated design, which is almost instantaneous. So it depends on your definition of slow closing. I used this one on a ground water heat pump, and it works great.

A:  Yes it can. You would have to go to the valve and turn the solenoid to manually open the valve. Hope this helps!
