1/4-28 Air Outlet Pressure Relief Valve, 1 psi, Viton seal

Description
Evaporation control units contain check valves that reduce the flow of vapor in or out of a solvent supply bottle. During a system run, as liquid solvent travels out of the supply bottle to the system, air must exit the bottle as solvent is added. This valve allows air to escape the bottle, but not enter (providing pressure relief.) Constructed from PTFE and Polypropylene with filter and Viton check element.
 
Air Outlet Pressure Relief Valve fits the following port caps:
WF-FS70-7, WF-70NAL-7, WF-83B-10, WF-100-10, WF-GL38-2, WF-GL38-3, WF-GL38-4, WF-GL38-7, WF-GL38-2, WF-GL38-3, WF-GL38-4, WF-GL38-7, WF-GL38-9, WF-GL-45-2, WF-GL-45-3, WF-GL-45-4
