What is the Purpose of a Quick Release Valve?

The function of a quick release valve is to rapidly exhaust air from the controlled device. It is normally located adjacent to the controlled device, rather than requiring exhaust air to return and exhaust through the control valve. This decreases release time.

What is a Valve?

Let us start by looking at the humble pipe. This could be a pipe transporting water in your bathroom or it could be a pipe carrying gas to your kitchen stove. In order to work efficiently, these liquid and gas pipes require a mechanism that can regulate the amount of fluid or gas passing through them; this mechanism can then be used to increase, decrease or even stop the flow of the liquid or gas. This mechanism is called the valve. They are mechanical switches that can turn pipes on and off and even raise or lower the amount of fluid/gas flowing through them.

Thus a valve is essentially a device or natural object that can be used as a fitting to direct, control, or regulate the flow of any fluid or gas by opening, closing, or partially obstructing various passageways. It does so by mechanically blocking a pipe either partially or completely to change the amount that can go through it. So one can find valves in any machine using liquids or gases. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The word is derived from the Latin valva, the moving part of a door, in turn from volvere, to turn, roll.

How do you know if a brake chamber is bad?

Cutting a push rod was as significant an issue as the clocking was.

5 common brake chamber issues.

‘The push rod is not fully retracting’

‘I received a DOT warning because my push rod lengths were greater than 6.4 mm or ¼ inch’

‘My brake chamber push rod is bent

‘The wheel end is consistently hot’

What does it mean when your air brake is leaking?

With the introduction of spring brakes, anti-compounding, and 121 air brake systems, because a valve is leaking air out of its exhaust, does not mean the valve is at fault. If a spring brake is leaking from the spring brake to the service brake side, that air will travel back up the service line and out the exhaust of the next valve back.

How can I troubleshoot my air brake system?

AIR BRAKE SYSTEM TROUBLESHOOTING 1.) Before replacing any valve with a new or remanufactured valve, be sure to blow the airlines out either using the vehicle's air supply or shop air. Dirt is the greatest cause of premature air valve failure. 2. ) If pipe dope is used on fittings, use it sparingly.
