    • A multi -position valve assembly (34) includes a valve body member (52) at least partially defining a body chamber (54) and a body orifice providing an inlet for ingress of a product into the body chamber (54). A stem member (56) includes a plug portion (58) at least partially located in the body chamber (54) and a stem portion (60) extending vertically from the plug portion (58) beyond a top of the body chamber (54). The stem member (56) includes a stem outlet (70) capable of communication with the body chamber (54) via a stem orifice (68). A first biases member (64) biases the stem member (56) toward a closed position. A second biasing member (72) biases the stem member (56) toward the closed position only after the stem memeber (56) is moved a clearance gap (86) to a first open position.
    • 多位阀组件(34)包括至少部分地限定主体室(54)的阀体构件(52)和设置用于将产品进入体腔(54)的入口的主体孔口。 柄构件(56)包括至少部分地位于主体腔(54)中的插塞部分(58)和从插塞部分(58)垂直延伸超过主体腔(54)的顶部的杆部(60) 。 杆构件(56)包括能够通过杆孔(68)与主体腔(54)连通的杆出口(70)。 第一偏压构件(64)将杆构件(56)偏压到关闭位置。 在第二偏置构件(72)仅在杆式构件(56)将间隙(86)移动到第一打开位置之后将杆构件(56)偏压到关闭位置。
