11 | 螺釘 Screw | 304SS |
上閥桿螺紋的潤滑脂與系統介質隔離 The lubricating grease on the upper valve rod thread is isolated from the system medium
閥桿和填料函接頭和閥體是相扣設計，防止閥桿脫離 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
手柄采用兩端螺釘鎖緊，穩固 The handle is firmly locked with screws at both ends
能耐高溫高壓,通過靜壓測試,防火防爆結構 It can withstand high temperature and high pressure, pass the static pressure test, and is a fireproof and explosion-proof structure
扭矩低,閥桿操作時絕對無泄漏 The torque is low, and there is absolutely no leakage when the valve rod is operated
