Manual Relief Valve

Description

The Manual Relief Valves are designed to be used in compact containers or cases. The Manual Relief Valves provide different ways to equalise pressure or vacuum differentials before opening the containers. These relief valves can be installed with ease through a single hole in the wall of the case. They also come with all attaching hardware. Some of the models come with the safety wire protection feature to prevent the unofficial opening of the valves. The suggested torque valve for installation of all Manual Relief Valves is 30lbs/ins. Do note that no visual indication is available to indicate if the Manual Relief Valves are open or closed. Careful consideration should be taken before selecting the valves due to possible outcomes from consistent exposure to the outside ambient if left open, and potential damage to the container if left closed.

Manual Relief Valve (Exhaust Port)

Featuring a physical overrule button to open the port, the Manual Relief Valve is an exhaust port that can be made use of as an inlet connection on containers. The self-sealing valve grants air an excess to the container but obstructs air from flowing out.

Even when the button is being depressed by users wearing arctic gloves, the side venting design allows the pressure to be equalised. Should the vacuum pressures exceed 6.0 psid, the unit may open automatically.
