Anti-blow out stem is a backseated design.
· 2O型密封圈,可有效防止泄漏
Two set of O-ring seals efficiently prevent leakage
· 密封剂注入器设计,可在紧急状态下注入密封胶,对阀杆或阀座进行密封
Sealant injection fittings for emergency stem or seat sealing
· 可选择的操作:提供手动、气动、电动等驱动方式
A wide choice of handle, gear, electrical, pneumatic or hydraulic operators can be supplied.
· 可选择的锁定装置
Optional locking device

All ball valves can be supplied in full compliance with NACE MR0175 Standard.
· 带波形、碟形、或圆柱螺旋形弹簧的浮动阀座设计
A floating seat with wave / disc / cylindrical spring design is provided.
·低压时阀座在弹簧预紧力的作用下,保证球与阀座间的低压密封
The preload of spring ensures bubble-tight sealing of ball and seat at low pressure.
·高压时阀座唇与球体全面接触,确保阀门的可靠密封性和较低的操作扭矩
At high pressure, the seat lip deflects slightly to ensure full seat-to-ball contact. This results in reliable sealing at high pressure and low operating torque.
