Valve

Various embodiments of the present disclosure provide a reusable valve (10) in which a seal portion (124) is co-molded with and overmolded to the valve stem (30) to provide a secure mechanical bond therebetween. In one embodiment, the valve includes a snap fit between the valve stem (30) and a retaining cap (50) to provide easy assembly of the valve as well as an efficient and compact retention mechanism for a biasing spring (40) and the valve stem (30) in relation to the valve housing (20). In one embodiment, the valve includes an easy-to-use opening and closing mechanism that provides tactile feedback to the user when moving the valve stem to an open position and to a closed position to inflate, deflate, or maintain air or gas pressure in the inflatable article. The present disclosure also provides a dunnage bag with such valve. 本公开的各种实施例提供了可重复使用的阀(10)，其中密封部分(124)与阀杆(30)共模制和过模制到阀杆(30)以提供在封闭部分和阀杆之间的稳固的机械连接。在种实施例中，所述阀包括阀杆(30)和保持盖(50)之间的卡扣配合以提供所述阀的简单装配以及偏压弹簧(40)和阀杆(30)关于阀外壳(20)的高效和紧凑的保持机构。在种实施例中，所述阀包括易用的打开和闭合机
