Wojin one-way degassing Valves/one-way degassing valve/air valve/coffee valve are designed to allow pressure to be released from an airtight package while not allowing external atmosphere to enter the package. Wojin offers two sizes of One-Way degassing valves, Model nos. WJ1901 and WJ1902. The one way valves are supplied with filter paper and without a filter paper. The filter paper stops small particles from clogging the one-way degassing valve.
