上阀杆螺纹的润滑脂与系统介质隔离 The lubricating grease on the upper valve rod thread is isolated from the system medium
阀杆和填料函接头和阀体是相扣设计，防止阀杆脱离 The joint between the valve stem and stuffing box and the valve body is designed to be interlocked to prevent the valve stem from separating
手柄采用两端螺钉锁紧，稳固 The handle is firmly locked with screws at both ends
能耐高温高压,通过静压测试,防火防爆结构 It can withstand high temperature and high pressure, pass the static pressure test, and is a fireproof and explosion-proof structure
扭矩低,阀杆操作时绝对无泄漏 The torque is low, and there is absolutely no leakage when the valve rod is operated
