What is a vent valve plug

  The vent valve is a sealed component by combining ePTFE film injection molding, ultrasonic welding and other forms. The main thread type, pressing type, buckle type and so on. The vent valve has two important indices: the amount of ventilation and the level of protection.

      Ventilation valve is usually suitable for outdoor lamps and lanterns industry, because the lamp has good air tightness and high local heat, which is easy to produce water vapor, thus will affect the use of lamps. The service life of lighting equipment can be prolonged after using the air vent valve. Automobile manufacturing industry is also one of the main markets for vent valves. When the temperature of parts rises sharply, there is water vapor mist, the internal and external pressure difference is unbalanced, and for oil and water seepage phenomenon, the vent valve can solve these problems with low maintenance cost. The vent valve is also often used in the solar photovoltaic industry, which can solve the problem of internal pressure difference caused by component heat dissipation and weather conditions.

      Our company provides metal and nylon two kinds of material vent valve products, with protection level reaches IP68.
