Description

Air release valve are used in the independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system. Because usually have certain air dissolved in water, and air solubility with the rising of temperature decreases, the water in the process of cycle gas gradually separated from the water, and gradually come together to form a big bubble column, even because there is water, so often have gases. Air release valve can eliminate the gas in the pipe, reduce drag and save energy. When the pipe is under pressure, the product can automatically inhale air to prevent the pipe from bursting.

Advantages

1.The valve body and inner parts are processed by precision CNC machine.
2.Each valve will be cleaned by Ultrasonic clearing machine before packed.
3.Each valve will be tested pressure before leaving factory.

Application

Operation of pipeline system,when the pipeline internal pressure or temperature changes and dissolved in the water of the air is released,air valves will be the timely discharge,prevent pipeline in formation of gas and affect the operation of the pipeline system.
In pumping station pressure tank tops and the water pipe on the installation of air valve for water conveyance pipeline during the initial water filling,regular maintenance of pipeline after water filling the air inside the pipeline to discharge,avoid pressure fluctuations; in pipeline water hammer negative, air valve opening, so that the tube outside air into the pipeline, lest in the pipe produced larger negative pressure, play a protective role.
