Low-Temperature Ball Valve

1.Usage

Low-temperature ball valve is suitable for the pipeline of class 150~1500,DN16~100,JIS10k~20K and used for severing and getting medium in the pipeline. Choosing different material can be suitable for different temperature and medium. The lowest working temperature is –254℃. The actuation modes of ball valve are of manual worm gear actuator, pneumatic actuator or electric actuator currently, The connecting types of ball valve are of flange and welding. 2.Scope of product Low-temperature ball valve has Low-temperature floating ball valve and Low-temperature fixed ball valve.it scope of product,face to face,flange connecting dimension can refer to the data of floating&fixed ball valve. For the temperature under –29℃ commonly, the neck length T is accordance with customer's Requirement and caculating, or relevant standards. 3.Structure feature Low-temperature ball valve is used for the Low-temperature working condition,Especially,Used for some dangerous medium condition of liquefied natural gas. For low-temperature ball valve's design, manufacture, test and inspection, Liangjin Group accumulates abundant experience. 4.Feature of structure design and manufacture Valve used for low-temperature medium, when it is in the position of closure.Low-temperature liquid medium resorted in the valve cavity will make the volume expand rapidly when the temperature raised to gasify.induce valve cavity pressure raise abnormally, Serious it ,it will make valve burst. Liangjing ball valve has the function of releasing automatically when cavity's pressure raised abnormally medium can depend on its own function to pull seat and release automatically to make sure valve's safe. Parts for valve in the disposal of ultra low temperature is to make sure the stability of parts' shape and size in the low temperature. Low temperature test: in the corresponding temperature conditions using nitrogen on the sealing performance of the valve testing.
