测试
阀门出厂前均经过1000psi (69bar) 氮气检漏，漏率不超过0.1std·cm3/min；
清洁和包装
阀门出厂前洁净度均依照《X-tec标准清洁包装》(X-C&P01)执行；
氧气应用和禁油装配的阀门均依照《X-tec特种清洁包装》(X-C&P02)执行；
应用及安全
BVS仪表球阀建议在室温环境下使用，苛刻的外部环境会造成密封失效；
当流体沿球面或阀杆出现微泄漏时，请拆下手柄调整填料螺栓；
温度交变会造成填料松弛，经过BVS球阀的流体请严格控制在 -10℃ ~ 90℃范围内，超过额定范围会增加填料螺栓调整的频率，降低阀门使用寿命；
通过带压流体时，BVS球阀手柄一定要在全开、全关或定位点，禁止停留在两位置之间；
如遇含有颗粒物杂质的流体时请在前端加装过滤装置，以避免阀内零件损伤增加维护成本；
发现操作手感异常时，请释放阀内压力后调整填料螺栓并补充润滑剂；
当应用高纯度氧气时，请参照《X-tec氧气系统安全应用》(X-S&A08)；
