LP2002 Coffee Valve Without Filter

The WJ2002 adopts a large outer diameter cap structure, which provides a wider force-bearing area when installed into the packaging bag by a heat press, thereby ensuring a more uniform distribution of heat sealing pressure and a more stable weld, greatly reducing the risk of air leakage or sealing wrinkles caused by uneven force; this product eliminates the filter screen in exchange for a more extreme exhaust rate and cost-effectiveness, and is specially designed for solid granular packaging.
