Snangda plastic waterproof breathable valve points: screw waterproof breathable valve. press waterproofbreathable, snap waterproof breathable valve. Shangda plastic waterproof breathable valve is a new type ofwaterproof breathable component. The waterproof breathable membrane is combined with plastic, siliconerubber and other materials through embedded injection molding and hot melt welding to form a sealedinstallation part. It can effectively prevent dust, water or other harmful substances from entering whilekeeping the internal and external pressure of the equipment flat.scale, with stable performance, simpleinstallation, extend the product life cycle,waterproof and breathable performance advantages.Shangda’s metal waterproof breathable valve mainly has two important indicators: 1, breathable volume2.
protection level
product features:
1. Highly sealed and dustproof: Screw-in valve body is designed to be equipped with O-ring seal byultrasonic welding, which allows the vent valve to be more effectively and tightly connected with the object.2.Convenient and quick installation: the installation torque reaches 0.7N.m,the thread is deep and has acertain length of guide position, which can quickly find the correct position for installation, and is not easyto slip and reduce maintenance cost quickly.
3. The structure is durable and stable: the design of ulitrasonic welding for the cover and hot melt weldingfor the membrane paper reduces the cost of seals and maintenance, saves space, has smooth and smoothteeth lines, has no residual burrs, is smooth and clear, is not easy to break, and has accurate dimensions4. temperature resistance and corrosion resistance: PA66/PC material, with flame retardancy, oxidationresistance, excellent electrical properties, good weather resistance characteristics: with high strength andelastic coefficient, high impact strength, the use of a wide range of temperature.5. Waterproof and breathable balance pressure: e-PTFE expanded polytetrafluoroethylene breathablemembrane is adopted, which can balance the pressure with high air permeability, effectively reduce thestress of the sealing strip of the shell, continuously discharge air to avoid damage to components and nutsdue to temperature rise. Multiple air holes are provided, so as to reduce heat dissipation and pressure,reduce residual water droplets after rain, and reduce water accumulation or fog for a long time.
