These Pressure Regulators are designed to balance the pressure between spraying and bypass pressure. Ideal for use with "weep" style spray wands used in self-serve car washes. Can also be used with multiple wand applications. These valves can also absorb normal pulsation eliminating the need for pulsation dampeners. Available in nickel-plated or brass bodies. Similar to widely used regulators that have been sold for years. Rated to 5 gpm and 2000 psi. Rated to 190° F.
