What Is a Quick Release Valve?

Using a quick release valve is a great way to get a quick release of air from your air brake system. Typically, a quick release valve is located near the chamber of a spring or pneumatic brake. It is designed to release air more rapidly than a standard control valve, which may result in less brake lag. In addition to speeding up the release of air, a quick release valve can also help reduce the lag time between the foot pedal and the brake release. This lag time is known as the "brake lag." Using a quick release valve will help reduce the lag time and make your air brake system function more efficiently.

There are a number of features to consider when deciding on the best quick release valve for your vehicle. Most quick release valves have a single supply port, but it is also possible to purchase one with two delivery ports. The valve can also be configured with a larger differential, which will help to speed up the release of air. The minimum sealing pressure for a quick release valve is 2 psi (.14 bar), and it is a good idea to install the valve as close to the actuator as possible. It is also a good idea to install a large diameter piping in the actuator discharge pipe.

A quick release valve also helps to reduce the time it takes to release air from the service brake chamber. Air is released through the valve quickly and can be applied to the brake system without having to travel back through the relay valve exhaust port. This is a useful feature if the vehicle is travelling on a slippery road. The valve is also a good way to help reduce wear and tear on drive components.

There are many quick release valves available, but they all share a few common features. Typically, they have two delivery ports, a minimum sealing pressure of 2 psi, and a minimum operating pressure of 150 psi. They can be operated in temperatures as low as -40 degrees Fahrenheit. They also come with an optional noise reducing foam cross, which can help to reduce the noise generated by the exhaust.
