There are many different locations within a pipeline where air valves are needed. Items sold by USABlueBook are intended for use only by professionals in the water and wastewater treatment industry. The CARD valve series is available in 1, 2, and 4 NPT (CARD100, CARD200, and CARD400 respectively). The high buoyancy float causes the poppet to have a large sealing force holding the large orifice tightly closed, regardless of system pressure, as long as it is higher than atmospheric pressure. Trapped air causes pump failures, corrosion, flow issues, water hammer and pressure surges. This mode is made possible by a combination of a lever and engineered force balanced float that allows the small degassing orifice to open even though the piping system is still under pressure. When air or gas accumulates again, the float drops and the valve reopens. In most cases, residual liquid and/or vapor in the valve may be expelled from the outlet port just prior to valve shut-off. Unique float design opens as air or gas collects in the valve, closes when liquid returns, allowing continuous expulsion of trace amounts of gas as it occurs. Sizes from 1/2 to 4 in a wide range of materials and connection types. 4054 Brewster Way Therefore, it is recommended to pipe the outlet port to a safe area for hazardous liquids, or use a standpipe for non-hazardous liquids.
