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 valves can be installed with ease through a single hole in the wall of the case and 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.
*No visual indication is available to indicate if the manual 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; potential damage to the container if left closed.
Featuring a physical overrule button to open the port, the Manual Relief Valve is an exhaust port that can be used as an inlet connection on containers. The self-sealing valve grants air an excess to the container but obstructs air from flowing out.
The Breather Valve is blacked anodised and has a restrained knurled twist knob for manual operation, and is utilised in thin wall containers. It can be mounted through a 0.50 inch (13mm) diameter hole. The unit, being IP67 rated, is entirely immersion proof and meets MS18014-1.
This “push-to-open” relief valve can be mounted through a 0.51 inch (13 mm diameter hole). 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.
This moderate-sized “turn-to-open” manual relief valve has a recessed captive screw that needs to be rotated once or twice with a screwdriver to open the valve. Apart from its safety wire feature, this valve can be set up through a 0.51 inch (13mm) diameter hole.
