Sanitary Quick Breather Valve Tank Pressure and Vacuum Adjustable Relief Valve
◎Sanitary Fermenter Safety Valves work in the following ways — From the Vacuum side, when the valve is normally closed and there is vacuum in the tank, the vacuum piston inside the valve opens automatically and draws air into the tank. In reverse, this keeps the pressure inside and outside the tank balanced. From the Pressure side, when the valve is normally closed and the tank pressure exceeds the rated pressure on the outside of the valve, the valve automatically opens and vents air to atmosphere.
◎As for installation of the clamp style Tank Pressure and Vacuum Relief Valve, position the valve on the process line and tighten the nut or fasten the clamp according to the fastening system selected and if you are using the clamp style it is recommended to use a clamp gasket and tighten the wing nut of the Heavy Duty Single Pin Clamp to 25 inch pounds of torque.
◎Note: Since this valve has been set at 15 psi (pressure), any pressure exceeding 15 psi, this valve will open and expel to atmosphere, thus protecting the tank from over pressurizing.
This Valve has been set at 15 psi (pressure) and -0.1bar (vacuum) and can not be changed.
Max pressure is 3.2bar, adjustable
Sanitary Quick Breather Tank Pressure and Vacuum Relief Valve Maintenance:
1. In order to use breathing valve safely, fire resistant layer should be removed periodically corrugated within 3-6 months, to clean, to ensure the smooth flow of each hole on the fire resistant layer,to prevent clogging, to ensure the safety of normal use.
2. Regularly check through the atmosphere positive and negative valve plate movement is flexible, guide rod and valve plate seal contact surface for damage, if damaged should be immediately exchanged.
3. In the inspection, maintenance reinstall, you should ensure that each binding plane quick breathing valve tight fit, flexible disc lift.
4. When the new valve opening should be installed before the purge valve disc between shockproof material, otherwise breathing valve failure.
Sanitary Quick Breather Tank Pressure and Vacuum Relief Valve selection:
1, the requirements for the installation location and temperature range requirements, it should be used as a cold-weather regions breathing valve (quick breathing valve), and should be installed in the pipe pipeline breathing valve selection.
2, the control valve pressure breathing should be related to the ability to adapt to the pressure.
3, breathing valve specifications (flange diameter) should meet the maximum out of the oil tank breathing gas flow requirements.
