Features

• Unlike burst valves, they can be used repeatedly, eliminating the need for valve replacement.
• Since it can handle high pressure, it can meet the demands for high valve opening pressure.
• The valve is compact (valve diameter: φ6 and up), allowing the unit to be designed freely and requiring minimal space even when multiple units are used.
• Since it can seal gases, electrolytes, etc., it can be attached to battery cells and the opening pressure can be controlled.
• By using cold-resistant rubber in the valve section, changes in valve opening pressure are reduced even in low and high temperature environments.
