  • Manual cryogenic valve operation

    2025/12/13 9:35:14

    Manual low temperature valve is operated by hand wheel and handle. It is widely used in petrochemical plant. Operators should pay attention to the following points:

  • Low temperature valve material cold brittle phenomenon

    2025/12/13 9:34:31

    Because the valve used in the pipeline is processed and manufactured according to the characteristics of the pipeline itself and the medium inside the pipeline, so it can also be said that the current valve structure is basically formed because of the many needs of the pipeline and medium. 

  • Low temperature valve valve knowledge

    2025/12/13 9:33:47

    Low temperature valve A control unit in a low temperature fluid delivery system that has the functions of diversion, interception, regulation, throttling, preventing backflow, shunt or overflow pressure relief. Applicable to the medium temperature of -40℃ to -196℃ valves are collectively referred to as low temperature valves.

  • A sticking problem in cryogenic valve use

    2025/12/13 9:33:05

    Now cryogenic pipeline is carrier of the city goods delivery, and some of them need to use a variety of auxiliary equipment, now the pipeline valve category, which is used to the cold of the pipeline valve, generally the cryogenic valve, this butterfly valve is used in the low temperature pipes, have lower friction

  • Why should low temperature valve be specified with long neck valve cover is what?

    2025/12/13 9:32:20

     The long neck valve cover has the function of protecting the stuffing box, because the sealing of the stuffing box is one of the keys of the low temperature valve. If there is leakage, it will reduce the cooling effect and lead to the gasification of liquefied gas. 

  • Starting and adjusting method of electro-hydraulic valve

    2025/12/13 9:31:30

    First of all, the air in the chamber of the main valve piston must be discharged, otherwise, the valve may work unstable or reduce the sensitivity. The VALVE IS INSTALLED IN A HORIZONTAL LINE, AND AIR IS AUTOMATICALLY DISCHARGED FROM THE UPPER CHAMBER OF THE PISTON, USUALLY AFTER SEVERAL COMPLETE SWITCHES.
