ARelief Air Relief Valve B Application Get control with the BradfordTM dependable air relief valve C which can be installed vertically on top of a tank, con- tainer or tube where air removal is required. Examples: 1.Bleeding of a tube line where an air pocket has formed. D This application calls for installation at the top of the tube. 2.Bleeding of a tube on the suction side of a pump. The E suction side is bled automatically, before the pump starts, establishing a vacuum. Binding of air to liquid will be prevented, and so will subsequent cavitation. In F this application the valve is mounted in front of the pump, on the top of the inlet tube. G Working Principle The BradfordTM air relief valve allows air to be removed from a line or container without the liquid flowing out. Its H design does not allow air to enter the line or container, even if subjected to a negative pressure. It is a double- seated valve with a freely moving polypropylene ball. The I ball, which is lighter than water, closes against the upper or lower seat, depending on the pressure conditions. J Features and Benefits � No tools for assembly or disassembly � The valve ball is constructed of FDA, 3A approved � The ball and gaskets are replaceable polypropylene K � The valve seals for both pressure and vacuum. The air � PTFE valve ball is available (density=0.078 lb/in3) and water can be directed away by using a plastic tube � Other gasket materials available and the 1/8" FNPT connection port on the valve L � All product contact surfaces have a radius of �" or better M Technical Data, Specifications and Dimensions N O P Q R S T Dimensions (in) Part Number Description A B C D E F G H J BARV-G150 air relief valve 1.98 1.4 1.5 --- 2.4 --- --- --- 1/8"NPT U BARVE-G150 3A air relief valve 1.98 1.4 --- 1.5 --- 0.37 4.5 1.1 --- � Note: all dimensions are in inches.
