1. high strength corrosion resistance:

is made of metal, the processing technology is more complex, but also has a higher strength and plated with an anti-oxidation layer, better corrosion resistance, not easy to rust; the product is beautiful and elegant, simple and shiny, long-term use of clean and bright as new.

2. Multi-channel spring pressure relief:

products are provided with a large-diameter vent ventilation channel and a pressure relief channel. The ventilation and pressure relief balance pressure. The high accuracy of the starting point can be automatically reset to continue use, protecting the sealing body from damage and reducing maintenance costs.

3. protection of high service life:

waterproof/dustproof/protection grade IP68/IP69K; prevent condensation and fog, improve product life.

4. Safety repeatable detection:

adopts the spring force top cover design, the blasting point can be directional and controllable, and the product can be tested for many times to ensure the qualified rate of 100.

5. General parts easy to install:

adopts the classic thread installation method and is equipped with a silicone rubber sealing ring, which can more conveniently fit into your product and reduce the maintenance cost of the sealing body.

6. Quick inflatable design:

waterproof and breathable explosion-proof valve is specially designed, and the supporting tooling can be quickly inflated, and the installation is convenient, which is convenient for the sealing inspection of the cavity.

When the sealed cavity is working normally and the internal pressure value is normal, SDA Shangda waterproof, breathable and explosion-proof valve products continue to exhaust the sealed cavity, waterproof, dustproof, breathable and explosion-proof. Under normal conditions, the increase in the external ambient temperature leads to an increase in the internal air pressure of the sealed cavity and the air flows outward. On the contrary, when the external ambient temperature decreases, the internal air pressure of the sealed cavity decreases and the air enters the cavity. At the same time, SDA Shangda waterproof, breathable and explosion-proof valve is built with e -PTFE membrane components to prevent dust, liquid and pollution and particles. When the internal pressure of the sealed cavity rises sharply and exceeds the set blasting value during abnormal operation, a large amount of gas pushes SDA Shangda waterproof, breathable and explosion-proof valve products to instantly complete direct connection with the outside, and a large amount of gas is discharged to quickly release the strong internal pressure of the sealed cavity to avoid explosion and reduce explosion damage. In addition, SDA Shangda waterproof, breathable and explosion-proof valve products have high starting point accuracy and can automatically reset and continue to use protective sealing body to reduce maintenance cost.
