PARKER電磁閥基本介紹
　　派克Bestobell提供范圍廣泛的高性能低溫截流閥，
　　其特點(diǎn)是采用*的松散凸緣螺栓閥帽設(shè)計(jì)。
　　該設(shè)計(jì)允許熱膨脹和收縮，
　　Anti-blowout stem design for operator safety.
of high performance cryogenic
　　globe valves, which feature a unique loose flange
　　專為低溫設(shè)計(jì)和設(shè)計(jì)。
　　The range is available with an actuated option,
　　using compressed air to open and a spring to close.
　　
　　bolted bonnet design.  The design allows for thermal
　　expansion and contraction, therefore eliminating the risk of leakage at the bonnet gasket.
　　Extremely durable, these valves deliver smooth
　　operation and reduced closing torque by use of a
