VENT VALVE

Application

The vent valve is installed vertically on the suction side of a pump at the top of a tank or at the highest point of an installation in order to release the entrapped air.  The valve remains open as long as there is an air flow, but closes as soon as the product reaches the valve to prevent the product from escaping.

Operating principle

The density of the freely floating ball is less than the density of water, when the product reaches the valve, the ball floats on its surface. As the product rises, the air can escape till the ball is forced to close the valve.

Design and features

Easy assembly/disassembly - clamp design, no tools required.
Standard connection: welding.
