The Inline Water Flow Regulator (Dole valve) is designed to deliver a constant volume of water flow over a wide pressure drop range. The constant flow of water is maintained by the use of the flexible orifice inside the inline water flow regulator (Dole valve). The flow rate is maintained to within ± 15% between 15 and 125 psi differential pressure of the water flow regulator. The flow rate varies due to manufacturing tolerances and water temperature. We manufacture the inline water flow regulator in various materials such as Nickel Plated BrassLead Free, Type 316 SS, and PVC. Water Flow Regulator comes in various flow rates and are 3/8”, ½”, ¾”, 1” FNPT, and 1 ¼”, 1 ½”, 2”, 2 ½”, and 3” MNPT and flow rates range from 0.5 to 120 Gallon per minute (GPM). We also use labels that provide extra-strong protection for harsh environments and conditions. They are constructed from durable polyester that is water resistant and tear resistant providing durable and secure protection. Our water flow regulator is marked with an arrow indicating direction of flow. To ensure proper operation, always install regulator with the arrow pointed downstream.
Maximum Operating Temperature: 212 Deg F

We needed to figure out how to properly split our 85 GPM flow rate unevenly over 4 fields and were pleasently surprise with these valves. These sork like a charm. Would highly recommend.
Great, prompt service as always from Yamatho. 1 gpm and 2 gpm Dole FR work great, provide consistent accurate water flow. Would recommend installing a banjo screen filter to protect orifice from plugging.
These flow regulators work. As long as you work them as specified, they deliver. The service was fast and price very reasonable.
Easy to order and high quality product
