- Wedgetorque操作机构提升，旋转90o，并且重新复位阀塞到其受到保护的阀座密封面内。积极的机械推力驱动阀塞进入阀体阀座馁，确保紧密双向管路密封。自动弥补由于磨损和温度波动而产生的变动。容易配置自动化执行机构。
Wedgetorque operator lifts, rotates 90o
and reseats plug on its protected seating surfaces. Positive mechanical
thrust drives plug into body seats to ensure tight bi-directional line
seal. Automatically compensates for wear and temperature changes. Automated
operation easily accommodated.
- 开启-关闭位置指示器。适用于远程指示的限制开关。
Open-close position indicator. Limit switches
for remote indication.
- 大型填料函可适应所有填料配置排列，包括适用于严酷应用环境的动负载结构和套环。
Large stuffing box accommodates all packing arrangements,
including live-loaded design and lantern ring type for severe services.
- 无润滑，锥形阀塞确保紧密密封，并且具有很低的启动扭矩。有硬化材料构造而成，配置备选硬面。
Non-lubricated, tapered plug assures tight seal
with low breakout torque. Constructed of hardened materials with optional
hard facing.
- 坚固耐用的阀体，配置具有研磨镜面光洁度的凸面阀座表面。可提供坚硬的阀塞和阀体阀座面。在开启-关闭位置，可防止管路流体介质进入阀体和阀塞阀座内。
Robust body with raised seating surfaces ground
to mirror-like finish. Hard plug and body seat facings available. Body
and plug seats protected from line media in open-close positions.
- 整体铸造阀体翼肋，与管路轴线平行和垂直，增加了阀体强度，适用于高压环境、高温和管道负载。
Integrally cast body ribs, running parallel and
perpendicular to the pipe axis, impart additional strength for high
pressure conditions, thermal and pipe loads.
- 七个阀体凸起部提供清洗，冲刷，排泄或旁路连接。(图示为清洗/冲刷)。底部凸起部配置标准管道螺纹。
Seven body bosses provide purge, flush, drain
or bypass connections. (Purge/flush shown.) Bottom boss is furnished
with standard pipe threads.
