Features

• By controlling the diameter of the umbrella-shaped lid and the repulsive force of the spring, it is possible to propose specifications according to the target valve opening pressure.
• After the internal pressure is released, the valve is closed by a spring force to suppress the inflow of oxygen and prevent the spread of fire.
• The structure of the metal or resin umbrella-shaped lid held by a spring allows for high-pressure cleaning. (Waterproof and dustproof IP67 and IPX9K compliant)
• Since it is equivalent to the flame retardant standard UL94 V-0, performance can be ensured during thermal runaway.
• Depending on the choice of mechanism, it can be easily installed with a single touch.
