Air pressure relief valve is a product used with the main function to help prevent backflow of air. Adjusting the air pressure in the ductwork system of high-rise buildings, manufacturing plants, large-scale works… Pressure relief valves can be designed with round air valves, square air valves, rectangular air valve.

So what is a pressure relief damper ? How does the pressure relief damper work? How to install the pressure relief damper correctly ? Please refer to the article below with P69 company !

What is a pressure relief valve?

The pressure relief air valve plays an important role in the stable and effective operation of the ventilation system. Is a type of wind valve that works according to the increase or decrease of wind pressure:

+ When the wind pressure increases to a certain limit, causing the vane of the air valve to open, the airflow is released.

+ On the contrary, if the pressure drops, the valve will automatically close.

Pressure relief air valves are commonly installed in high-rise buildings, with closed architectural design, high risk of pressure increase.

Design features of the pressure relief air valve

Air pressure relief valve is currently one of the important accessories in the duct system in high-rise buildings, factories or commercial centers. Duct exhaust valve products are distinguished by the following characteristics:

+ Diverse sizes, each type will have specific applications suitable for the project. Depending on the needs of use or each project to choose the appropriate duct pressure relief valve size.

+ The material is made of zinc-aluminum coated steel, with high durability and resistance to oxidation, suitable for the hot and humid weather conditions of our country and ensures absolute safety for large projects or works. At the same time, ensure long-term use.

+ The highlight of the pressure relief air valve is the installation location. The product has many designs, so it can be installed on the wall, on the air duct in the vertical or horizontal mode.

+ In addition, the pressure relief valve is also distinguished by diverse designs in terms of designs and designs such as: round duct pressure relief valve, square duct pressure relief valve … Depending on each specific project to choose suitable type.

Working principle of pressure relief air valve

Basically, the pressure relief air valve works completely automatically based on the principle of pressure balance. The valve opening is changed according to the pressure of each specific pipeline.

When the pressure in the pipeline increases beyond the selected amount. From 30-150 Pa can be up to 300 Pa, then the valves open to relieve pressure. Next, when the pressure in the pipeline drops to the selected minimum, the valve will close so that the pressure is stabilized to a safe level.

Instructions for installing pressure relief air valve

The process of installing the pressure relief air valve is very important. Check out the steps to install the pressure relief damper right away standardize all the procedures below

Step 1: Check the pressure relief air valve

First of all, it is necessary to check and measure whether the size of the one-way air valve is suitable for the size of the pipeline system to be installed. Is the valve material suitable for the use environment and the valve connection type compatible and convenient with the location to be installed? Is the ventilation speed consistent with the valve’s ability to open and close?

Step 2: Determine the location to install the pressure relief air valve

Next, proceed to determine the position installation of the pressure relief air valve on the pipeline system by observing the direction of the arrow indicating the direction of the wind in the valve. If the arrow is horizontal, install the valve horizontally, and if the arrow is up, install the valve vertically. After determining the exact location and installation direction, use the tool to proceed.

Step 3: Clean the air valve and the installation position of the air valve

Observe the inside and outside of the pipe and valve parts and then clean it to make sure there is no garbage and dirt trapped inside. Because as long as there is dirt stuck, the valve disc will not be able to open and close. Thereby affecting the operation of the system

Step 4: Install the pressure relief air valve

Finally, proceed to attach the one-way air valve to the position to be installed according to the design and selection in the above steps.

Step 5: Check the pressure relief air valve

Conduct a test run of the air valve to check that its is installed correctly. If the air valve works stably, only allowing the wind in a certain direction without obstruction or stopping, then you have successfully installed it can be put into operation. if you notice any other problems, you must quickly disconnect to check and handle.

How to use pressure relief air valve?

The pressure relief valve plays an important role in the operation of the ventilation system. With a pressure-based operating mechanism, pressure relief air valves are installed in many high-rise buildings with closed design, high risk of pressure increase.

The pressure relief air valve is installed according to the internal rules, so the user can easily adjust the position to suit the pressure requirements. The pressure release feature is based on the principle of balancing the valve leaves.
