Specification Features: 1. Easy to install and easy to use. 2. For water pressure exhaust. The water cooling system is mostly closed. As the temperature of the cold liquid rises, internal pressure will be generated. The internal pressure will increase the crushing capacity of each joint and indirectly affect the service life of the system. stability. By releasing the internal pressure, it can improve the operation stability of the water cooling system and obtain the best state of low pressure operation. 3. As the internal pressure discharge device of the water cooling system, this exhaust valve should be installed above the water level of the pipeline. If it is installed in the water tank, it must be installed above the water tank. It is forbidden to install under the water tank or below the water level of the pipeline, which will cause water seepage. 4. Automatically air exhaust without manual pressing. 5. Excellent quality and durability.
