Low Temperature Valve

  Material Selection
 
Goole Valve uses materials with excellent low-temperature performance (such as austenitic stainless steel, nickel based alloys, etc.) to manufacture low-temperature valves, ensuring that the valves can maintain good strength and sealing performance at extremely low temperatures.
 Sealing Technology
 
Advanced sealing structures (such as metal hard seals, elastic seals, etc.) are used to ensure that the valve does not leak under high pressure and low temperature conditions.
 
 
 
Structural Design
 
Special structures such as long neck valve cover and anti-static design improve the safety and reliability of the valve.
 
 
 
 

Safety Valve And Relief Valve

  Overpressure Protection
 
The safety valve can automatically open when the system pressure exceeds the set value, releasing excessive pressure to prevent equipment damage and accidents.
 Release Control
 
Release valves are used to release pressure and maintain system stability when needed. These valves play a crucial role in the storage and transportation of LNG.
Control Valve And Regulating Valve
Flow regulation: By precisely adjusting the opening of valves, precise control of flow can be achieved to meet different needs in LNG processing.
Pressure regulation: The regulating valve can maintain the stability of system pressure, ensuring the continuity and safety of LNG processing.
Control Valve And Regulating Valve
In response to the special needs of the LNG industry, Goole Valve also offers a range of special material valves (such as titanium valves, nickel valves, zirconium valves, etc.), which have excellent corrosion resistance and low-temperature performance, suitable for the storage, transportation, and refueling processes of LNG.

The Key Role Of Valves

Valve Function During LNG Storage Process

  Control Inflow And Outflow
 
Low temperature valves are used in the inlet and outlet pipelines of LNG storage tanks to precisely control the inflow and outflow of LNG. These valves can ensure the stability and safety of LNG during storage, preventing safety issues caused by excessive or insufficient flow.
 
  Protect Storage Devices
 
 
Valves also play an important role in protecting storage equipment. For example, when the internal pressure of the storage tank is too high, the safety valve will automatically open to release the excessive pressure to prevent the tank from being damaged due to overpressure.
 
  Prevent Overpressure And Negative Pressure
 
To prevent overpressure or negative pressure accidents in low-temperature storage tanks, the tanks will be equipped with corresponding pressure relief valves and nitrogen filling systems. The collaborative work of these valves and systems ensures that the storage tank operates within a safe pressure range.

Valve Function During LNG Transportation

  Ensure Secure Transfer
 
 
Low temperature valves play a crucial role in the loading and unloading process of LNG carriers. They can ensure the safe transfer of LNG during transportation, prevent leaks and accidents.
 
  Adjust Flow And Pressure
 
 
Valves are used in transportation pipelines to regulate the flow and pressure of LNG. This helps ensure the stability and controllability of LNG during transportation, thereby avoiding potential safety risks.
  Emergency Shutdown Function
 
In case of emergency during transportation, such as vehicle accidents or leaks, the shut-off valve can quickly close the pipeline to prevent further liquid leakage, thereby protecting the safety of personnel and the environment.

Valve Function During LNG Refueling Process

  Control The Filling Amount
 
At LNG refueling stations, valves are used to precisely control the amount of refueling. This helps ensure safety and accuracy during the filling process, preventing waste or safety issues caused by over or under filling.
 
 
  Adjust The Filling Speed
 
 
The valve can also adjust the filling speed of LNG. By adjusting the opening of the valve, the flow rate of LNG can be controlled to ensure a smooth refueling process.
 
 
 
  Protect The Refueling Equipment
 
During the filling process, the valve also plays an important role in protecting the filling equipment. For example, when the filling pressure is too high, the safety valve will automatically open to release the excessive pressure to prevent damage to the filling equipment due to overpressure.
It is an intelligent manufacturing enterprise that integrates production, sales, and services, with mature technical strength, advanced production equipment, strong production capacity, and excellent service team.
