다수의 변형예는, 밸브(12)의 고정 본체(46)에 의해 형성되는 공동부(56)에서 밸브(12)의 가동 스템(48) 주위에 위치되며, 스템(48)의 운동을 용이하게 해주는 부싱(100); 및 공동부(46) 내부에서 부싱(100)의 내측에서 스템(48) 주위에 위치되는 시일 부재(102, 104)를 포함하는 제품을 포함할 수 있고, 시일 부재(102, 104)는 스템(48)의 외경면(76)과 시일 부재(102, 104)의 대면하는 내경면(120, 128) 사이의 유체 유동을 실질적으로 방지하여 제 1 시일을 형성하게 된다. A number of variations may include a product comprising: a bushing (100) located at a cavity (56) formed by a stationary body (46) of a valve (12), and located around a movable stem (48) of the valve (12), wherein the bushing (100) facilitates movement of the stem (48); and a seal member (102, 104) located in the cavity (46), around the stem (48), and on the inboard side of the bushing (100), wherein the seal member (102, 104) substantially prevents fluid-flow between an outer diametrical surface (76) of the stem (48) and a confronting inner diametrical surface (120, 128) of the seal member (102, 104), forming a first seal.
