  • Low temperature valve main material selection

    2025/12/13 8:34:22

    From the metallographic perspective, in addition to austenitic steel, copper and aluminum with face-centered cubic lattice in metal materials, the general steel will appear low-temperature brittleness at low temperature, thus reducing the strength and service life of the valve. When selecting the main material, the material suitable for working at low temperature should be selected first. 

  • Fault judgment and elimination of electro-hydraulic valve

    2025/12/13 8:33:35

    Electro-hydraulic valve is a reasonable control valve in principle and structure at present. The rationality of its structure is fully reflected in fault judgment and maintenance. 

  • Leakage of cryogenic valves

    2025/12/13 8:32:39

    Low temperature valves include low temperature ball valve, low temperature gate valve, low temperature globe valve, low temperature safety valve, low temperature check valve, low temperature butterfly valve, low temperature needle valve, low temperature throttle valve, low temperature pressure reducing valve, etc., suitable for medium temperature of -40℃ ~ -196℃ valve.

  • Functional characteristics of multifunctional electro-hydraulic valve

    2025/12/13 8:31:48

    can be multi-section open, closed, eliminate water blow. For a general oil system, the impact pressure of the water hammer often exceeds the maximum pressure limit of the relevant equipment on the pipeline, sometimes even up to more than 3 times. This is enough to cause the pump, valve, flowmeter, pressure gauge

  • Low temperature valve industry development status

    2025/12/13 8:30:49

    Low temperature valve is a kind of small functional device used in industrial and urban construction, whose work is to control the activity state of the medium (liquid, gas, powder) in the pipe and equipment. Low temperature valve in the management of its role in the characteristics of the classification

  • Manual cryogenic valve operation

    2025/12/13 8:29:55

    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:
