Brass Pressure Relief Valve 6815 - by Spraying Systems 300PSI & 700PSI

Rittenhouse only sells the HSS (hardened stainless steel) version of this regulator. Do not be fooled into buying the cheaper brass version, which will have a much shorter lifespan.

All of our 6815 regulators have hardened stainless steel seats for a longer life and more accurate pressure control. Don't be fooled into getting anything but a regulator which has hardened stainless steel seats.

Specify whether you require a 300 psi or 700 psi model.

As with all pressure regulators or pressure relief valves, these have wearing parts. The friction of the water or spray passing through the regulator will wear some parts. So it is recommended that when you buy a new regulator, you also purchase the repair kit.

**** Spraying Equipment Tip ****
Many times when our customers report low pressure problems with a pump, the actual problem is with the relief valve and not with the pump. To find out which componenent is failing, turn on your spraying system, check inside the tank to see if you are getting lots of return back to the tank. If you are, then it is your relief valve which is weak. When a pressure relief valve is failing it allows all the pressure to return to the tank. You will also notice that the handle is screwed all the way down to the bottom.

The port on the side of the 6815 is the return port back to the tank. Do not restrict the flow of the return line, it may cause damage to your pump.

Repair Kit Includes: spring retainer, gasket, inner & outer springs, guide seat and inlet adaptor. Hardened stainless steel seats for wear resistance. Please specify 1/2" or 3/4" when ordering.

• Free floating seat design improves overall speed and sensitivity of regulator.
• Solid brass body with hardened stainless steel seats for long life.
• Extra large valve passage provides full flow through the valve with minimum pressure loss.
• Available in 1/2" and 3/4" pipe sizes male NPT inlet and female NPT outlet.
• Specify 0-300 or 0-700 psi model when ordering.

The chart below shows the maximum flow rates possible onan unrestricted 300 PSI or 700 PSI model of the TeeJet 6815 Brass relief valve. Remember that bushing down your outlet will reduce your flow by restricting the inside diameter of your flow path.

	Maximum Flow in GPM through the TeeJet 6815 valve at various pressures in PSI. (With valve unrestricted.)
	10 PSI	15 PSI	20 PSI	25 PSI	30 PSI	35 PSI	40 PSI	50 PSI	60 PSI	70 PSI	80 PSI	100 PSI
GPM	18	23	26	29	32	34	36	40	44	47	50	56
