TECHNICAL DATA

With no check valve holding the pressure from returning into the un-loader from the outlet, the pressure through out the system is relieved each time the unloader cycles. A cycle consists of the unloader supplying water to the outlet, and then diverting it to the by.

Unloader Valve and Orifice Guide

If your air compressor has an integrated mechanical unloader valve it is not necessary to remove it, it can be left in place and an electronically operated valve can be added. Unloader Valve Plug The plug that is installed into the drain valve should have an orifice sized so the pressure release / air purge after the compressor has run should take about 5 seconds.

Understanding unloading valves — Part 1

Valve designers select the spring so that the differential pressure required for cracking the unloader spool (just starting to open) requires from about 50 psi to as much as 250 psi. The higher pressure provides for better control, but it also results in higher unloading.

Pressure Washer Unloader

Bypass Port 3/4" MPT Discharge Pressure TO PSI This unloading valve is a flow-through design and should be mounted on the discharge line of the pump in A pressure gauge should be installed on either side of the port of the unloader to accurately read pressure during adjustment.

What Is An Unloading Check Valve?

A visitor asks the question "what is an unloading check valve" as it pertains to air compressors. These are one of the devices companies have manufactured to emulate the unloader valves that are commonly attached to, or part of, the air compressor pressure switch.

What is an unloader valve?

The unloader valve can also be used for adjusting the pressure of your machine. The trigger on the gun and unloader valve together make up a two-part valve that directs water into the bypass of the unloader valve and then back in to the water inlet side of the pump or alternatively back to a header tank.

CHAPTER 9: Relief and Unloading Pressure Controls

The unloading valve is set at 500 psi to divert flow from the high-volume/low-pressure pump to tank when system pressure climbs above this setting. A check valve after the high-volume/low-pressure pump isolates system pressure from the unloading valve circuit while performing work at maximum pressure.

CHAPTER 9: Relief and Unloading Pressure Controls

The valve has a poppet that is pressed against its seat by an adjustable spring. An adjusting knob can be change the force on the spring to raise or lower maximum pressure. The poppet remains seated while pump flow goes to the circuit and pressure is lower than the relief valve setting.

How to Adjust Unloader Valve on Pressure Washer? …

 · When adjusting the valve, the motor should be running, but make sure it is set at the appropriate rpm (usually before a load and under a load). Now, remove the nylon insert lock from the unloader valve then shut off the pressure adjusting knob. ….

How It Works: Piloted Unloader Valve

As tank pressure approaches 135 PSI, the unloader valve should begin unloading at felt muffler and cause gas engine to slow down to idle speed. If pilot valve does not unload as tank pressure approaches 135 PSI, slowly turn top end setting (4) ….

How Does a Pressure Washer Unloader Valve Work? …

 · Unloader valves allow you to decrease or shut down the pressure entirely. On top of that, you can do it quickly, which means there is a much smaller chance of doing any real damage. It's much more likely that someone may be injured if you have to ….

Proper unloader adjustment

 · Unloaders may regulate pressure regulator, as well as, serve as a type of safety relief valve. When an operator releases the trigger on the gun the pump will continue to build pressure in the line. The unloader senses the pressure buildup and by opening and closing a series of internal check valves it takes the water from the pump and recirculates it back to the tank or inlet depending on how.
