Vacuum negative pressure relief valve is only suitable for vacuum relief is required. In the working state, a spring or load tray can be used to achieve the purpose of air intake release. This feature can reduce the probability of tank damage as much as possible. The size of the valve matches the vacuum valve required under operating and thermal conditions. This model supports flow curves.
The relief valve has an "air cushion" base. As a standard FEP base partition, it has good performance and can reduce the adhesion caused by resin vapor and environmental humidity. The vacuum negative pressure relief valve has an automatic discharge cover and drip ring, so that the base surface does not contact condensate and ice. This design also prevents an increase in vacuum due to adhesion and clogging of the vents. Metal, Buna-N, Viton and other base diaphragms are available if required. If high configuration is required for sealing tank or other types of installation, the vacuum negative pressure relief valve can be loaded with spring. For the correct alignment of the base surface, the device has a rod with peripheral guidance and central stability.
