F2 系列浮动球阀－Floating Ball Valve供应

F2 系列浮动球阀－Floating Ball Valve 提供手动、气动、电动等驱动方式

主要设计特点－Main Designing Features

· 可调节的防火阀杆填料

Adjustable fire-safe stem packing

· 凸起的防火唇作为金属辅助密封阀座，符合API 607标准的防火要求，且可阻止流体对阀座内侧的冲蚀和阀座的冷流

The raised fire-lip acts as metal backup seat meeting API 607 through leakage requirements, and protects the seat from abrasion of flow and seat cold flow

· 防吹出阀杆

Anti-blow out stem

· 防静电装置

Anti-static device

· 可适合于任意方向的切断

Full rated bi-directional shut off

· 可选择的带锁手柄

Optional lockable handle

· 缠绕式垫片，防止外漏

Spiral wound gasket, prevent external leakage

· 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.

· 符合NACE规范要求

All ball valves can be supplied in full compliance with NACE MR0175 Standard.

· 弹性阀座

Self-compensation seat

·低压时阀座位置 Seat Position at Low Pressure

低压时阀座弹性唇在装配预紧力的作用下，保证球与阀座间的可靠密封及阀门的最低的操作扭矩

An integral seat lip provides positive low pressure “bubble-tight” sealing of ball and seat. The assembly preload ensures constant surface load of ball to seat with minimum operating torque.

·高压时阀座位置 Seat Position at High Pressure

阀座唇在高压时的轻微变形使球与阀座全面接触，可恢复的弹性唇保证高、低压时的可靠密封性，并确保阀门较低的操作扭矩和更长的使用寿命。

The seat lip deflects slightly at higher pressure to ensure full seat-to-ball contact. The seat’s “memory-action” provides bubble-tight sealing at low and high pressure. The feature results in low torque and long life operation.
