name: waterproof ventilation valve also known as: breathing apparatus,breathable plug, breathable screws,etc.
metal waterproof breathable valve
is a new type of waterproof and breathable component The waterproof and breathable membrane is combined withother materials such as metal and silicone rubber to form a sealed installation part. It can avoid dust, water or otherharmful substances from entering while maintaining the pressure balance inside and outside the equipment. It hasthe advantages of stable performance, simple installation, prolonged product life cycle, high waterproof andbreathable performance.
Explosion-proof pressure relief valve
is a new type of waterproof and breathable components, the connecting rod structure through the form of springcompression, combined with metal, silicone rubber and other materials to form a sealed installation parts; can avoiddust, water or other harmful substances into the device while maintaining internal and external pressure balance, ithas the advantages of quick pressure relief and explosion-proof, high precision of starting explosion point, automaticreset and continuous use after blasting, stable performance, simple installation and extended product life cycle.

plastic waterproof ventilation valve

is a new type of waterproof and breathable component. The waterproof and breathable membrane is combined withplastic, silicone rubber and other materials through embedded injection molding and hot melt welding to form asealed installation part. Avoid dust, water or other harmful substances from entering while maintaining the internaland external pressure balance of the equipment. It has the advantages of stable performance, simple installation,prolonged product life cycle, and high waterproof and breathable performance.Main technical indicators identification and parameters:
1. Protective performance, now the industry generally uses IP protection level description, such as IP65 IP66 IP67IP68 waterproof, the higher the protection level, the better.2. Air permeability: This is the key indicator, which refers to the air permeability of the air valve,that is, the airpermeability per unit area and unit time under a certain air pressure. Our company is generally under @ p= 7KPa,how many liters per second per square to measure the effect of ventilation.3. Environmental adaptability: It is the tolerance of the environment, including temperature aging, UV aging, and airpermeability attenuation that has been encountered in common pollution such as water, dust,and oil.
4. Product parameters:Main material: polycarbonate PC,aluminum alloy, stainless steel, copper, etc., Waterproof membrane material:expanded polytetrafluoroethylene (e-PTFE)
water resistance pressure difference: 12~20KPa protection grade: IP65 to IP68Working temperature:-40’C ~120 C O-ring material: silica gel 60 Shore hardness A
