Multiple Models of Air Tank Pressure Relief Valves Available
The price of the pressure relief valve is determined by the model, with different models having different prices. The model of the pressure relief valve is also determined based on the inner diameter of the air outlet pipeline of the on-site air tank. Customers can select the appropriate pressure relief valve according to the models listed above. We will provide you with a suitable price based on your specific situation, and our company will also offer you a favorable price. Welcome to call.

This pressure relief valve is installed in the air compressor system on the air tank outlet pipeline directly facing the airflow direction. When the air compressor system is operating normally, the system pressure is ≤0.785MPa (8kgf/cm²). Under this pressure, the pressure relief valve functions normally. When the air tank ignites due to carbon buildup or the gas inside the tank becomes dangerous for some reason, the temperature and pressure in the system instantly rise. When the pressure reaches 1.04±0.059MPa (10.6±0.6kgf/cm²), the pull rod immediately breaks, the pressure relief valve releases pressure, and the high-temperature, high-pressure gas in the air tank and pipeline is rapidly released, thereby mitigating shock waves and preventing major accidents.
