Bestobell 超低温球阀Cryogenic Ball Valves

派克旗下品牌Bestobell的超低温球阀具备优异的流量性以及较长使用寿命。其创新设计允许介质流体实现全流量，充装站和便携式输送系统的流量输送实现较低压力损失而实现快速充装。Parker Bestobell's cryogenic ball valves are ideal where excellent full flow characteristics are required with no delay in filling time. They are widely used in gas production, transportation and storage, offering long term performance.

派克旗下品牌Bestobell的超低温球阀是设计用于液化气生产、运输和储存系统。这些阀门具备优异的全流量特性以及较长使用寿命，是客户需求中的理想选择。该阀门的新颖设计允许介质流体实现全流量，充装站和便携式输送系统的流量输送实现较低压力损失，从而实现快速充装，充装时间没有延迟。Parker Bestobell's cryogenic ball valves are specially designed for use in liquefied gas production, transportation and storage. These valves are ideal where the customer requires excellent full flow characteristics and long term performance. The innovative design of the valve allows for full flow of media from filling stations and portable delivery systems with low pressure loss, resulting in no delay in filling time.

这些球阀采用了新型的自由浮球式设计，允许上游压力的力量推动球芯与下游端的阀座密封，压力越高，压紧阀座力就越大，同时需要更大的扭矩开关阀门。 These ball valves feature an innovative free floating ball design that allows the force of upstream pressure to push the ball hard against the downstream seats. The higher the pressure, the more seating force and torque is required to operate the valve.

铜材质和不锈钢材质可选，球阀具有弹性压盖密封，在环境温度和超低温条件下都能提供较低的操作扭矩。Available in Bronze and Stainless Steel, the ball valves feature a spring-loaded gland seal, which provides low torque level under both ambient and cryogenic conditions.

派克Bestobell超低温球阀为无泄漏而设计，较大限度地提高使用寿命和降低维护成本。 Parker Bestobell's cryogenic ball valves are designed to eliminate leakages, maximise lifetime operation and reduce maintenance costs.
