Manual Relief Valve

Manual Relief Valve

The Manual Relief Valves offer various methods to equalise vacuum differentials or pressure before opening the containers. They are equipped with attaching hardware and can be easily installed on the wall of the case. Some models even come with a safety wire protection feature to prevent the containers from unauthorised openings of the valves. The torque value for the installation is 30 lbs/ins.

The Manual Relief Valves are available in different models:
