Air Release Pressure Vacuum Relief Breather Valve

Breathing valve produced by our company has simplified structure, ventilation volume, less leakage, corrosion resistance, insulationetc.
The valve adopts polytetrafluoroethylene material, has the advantages of low temperature resistant, anti frost. 
The electrostaticprotection device is provided with a respiratory valve, the valve and the tank to keep the same potential moment

Product Feature:

Breathing valve is a kind of air breather which install on the petrochemical fixed storage tank, in order to avoid tank over the pressure or vacuum making the storage tank destruct, prevent the outside flame enter, reduce the tank fluid volatile.

Breathing valve is to maintain the tank pressure balance, reduce safety energy-saving products medium volatile, but also the use ofprinciples of vapor heat transfer, protect the respiratory valve parts is not easy to freeze, the breathing valve to ensure the normal work.

Installation :

1.Removing packaging and reading product instructions are critical.
2.When lifting the breathing valve, appropriate lifting tools should be selected to avoid damaging the protective cap of the valve disc.
3.Check the coaxiality and verticality of the pipe flange on the tank or water tank. The normal use of the Pressure Vacuum relief valve is very important.
4.Check the line surface of the pipe flange on the tank or water tank. It must be clean, free of scratches, corrosion, tool traces and flat.
5.Remove flange end cover and other packaging materials.
6. Check the gasket and make sure that the material is suitable for application.
7. Use bolt circles to center the washer.

Working principle:

1. When the pressure of the medium in the tank is within the control operating pressure range of the breathing valve, Pressure Vacuum relief Valve with Pipe  / Breather valve with Pipe does not work and keeps the tank closed.
2. When the medium is added to the tank, the pressure of the upper gas space in the tank rises, reaching the positive pressure of the operation of the breathing valve, the pressure valve is opened, and the gas escapes from the exhaust outlet of Pressure Vacuum relief Valve with Pipe  / Breather valve with Pipe, so that the pressure in the tank does not continue to increase.
3. The atmosphere outside the tank will open the negative pressure valve disc of Pressure Vacuum relief Valve with Pipe  / Breather valve with Pipe.
