Dole Water Flow Regulator Technical Information

Dole flow regulator flow characteristics

Dole brand water flow regulators are self-cleaning and constructed to deliver consistent water flow output over a wide range of pressure drops. A flexible orifice insert varies the water flow volume inversely to the water pressure forced against it. Below the threshold pressure the orifice insert acts as a fixed orifice. Above the threshold pressure point the orifice insert begins to distort, effectively reducing the orifice area to sustain the water flow output desired. The water flow rates will remain constant to within plus or minus 15% up to a a pressure drop of 125 psi. The flow rate can vary due to manufacturing tolerances and water temperature. These regulators are rated for potable water systems below 180°F. and a maximum pressure of 200 psi. Where possible, multi-orifice flow inserts are used for regulators with rates between 1 and 4 gallons per minute. Multi-orifice inserts break up the water discharge pattern to help minimize sound caused by water passing through the restriction.

Please note: While we strive to ensure every product we label as "Made in the USA" really is 100% made in the USA, it is also important to understand that sometimes manufacturers make changes to their products, or for various reasons may receive components or materials that they would normally purchase domestically from an overseas supplier - and they don't necessarily let distributors (like us!) know that they've changed something about the product or where it is manufactured.

If you receive a product that PlumbingSupply.com® says is "Made in the USA" and the product states it was manufactured elsewhere, please contact us. We will happily replace or refund your purchase to your satisfaction.
