Simtech AVV 402 5 010 1" Aeratation Vent Valve Spigot

Simtech, AVV 402 5 010, 1" PP/FPM Aeratation Vent Valve Spigot (32mm)

When fluid is removed from a tank, the valve ball/float is located at the bottom of the valve. Air or protective gas can flow into the container, providing pressure compensation to ensure that the tank is not damaged by a vacuum. When the container is filled again, the air/protective gas escapes through the valve into the atmosphere until the fluid level reaches the valve ball/float. When the container is filled further, the valve ball/float rises with the fluid level and seals the container at the valve seat.

Features:

• Mounting in vertical position only;
• High level of operating safety and long service life;
• When the valve is closed, venting is only possible when the container pressure falls below the atmospheric pressure even with air build-up (outgassing media);
• The valves are not suitable for fluids that clog or gum up the balls/floats, impairing their opening and closing action;
• Low-maintenance.
