Their most common applications are in pneumatic suspensions and exhaust brake chamber cylinders. A special version with a double pilot clapper is used for systems with spring brakes. Log in to view stock and order.

QRV’s are available in four sizes for direct connection to 3/8, 1/2, 3/4 and 1 inch pipe. Models are also available which permit 1/2, 5/8 and 3/4 inch outside diameter tubing connections to the QRV inlet port. Exhaust noise from the valve can be reduced by using a muˆer, which threads into the tapped hole in the end cap. 1.2 How it works ...

The Airflex quick release valve (QRV) is a pneumatic in-line, three-way valve designed to automatically close upon pres-surization and open to exhaust when a pressure drop occurs in the supply line. The valve provides an exhaust port close to the pressurized chamber of the device being controlled rather

Porting consists of one supply port, two delivery ports and one exhaust port. When a brake application is made, air pressure enters the supply port; the diaphragm moves down, sealing the exhaust. At the same time, air pressure forces the edges of the diaphragm down and air flows out the delivery ports.

The Airflex® QRV is a quick release valve that facilitates the release of air from a pressurized chamber i.e., air cylinders, clutches, brakes or other pneumatic devices. In essence it provides an exhaust port at the chamber rather than exhausting through long …

The QRV quick release valve is the oldest design and utilizes a die cast metal body with an internal diaphragm, spring and spring seat. The QR-1 quick release valve also has a die cast body and diaphragm, but does not employ a spring or spring seat.

Quick release valves ensure that air can be released rapidly. Their most common applications are in pneumatic suspensions and exhaust brake chamber cylinders. A special version with a double pilot clapper is used for systems with spring brakes.
