Flow regulator (Dole valve) PVC , FNPT, 1.0 to 30 GPM with Buna rubber orifice

Description

DESCRIPTION
The 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. The flow rate is maintained to within ± 15% between 15 and 125 psi. The flow rate varies due to manufacturing tolerances and water temperature. We manufacture flow regulators in various materials such as Nickel Plated Brass, Type 316 SS, and PVC. Flow Regulators come 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. All Flow Regulators are marked with an arrow indicating direction of flow. To ensure proper operation, always install regulator with the arrow pointed downstream.
