Vacuum Insulated Shut-off Valve
Product Application
The Vacuum Insulated Shut-off Valve is an essential component in any cryogenic system, designed for reliable and efficient control of cryogenic fluid flow (liquid oxygen, liquid nitrogen, liquid argon, liquid hydrogen, liquid helium, LEG and LNG). Its integration with Vacuum Insulated Pipes (VIPs) and Vacuum Insulated Hoses (VIHs) minimizes heat leak, maintaining optimal cryogenic system performance and ensuring efficient transfer of valuable cryogenic fluids.
Key Applications:
- Cryogenic Fluid Distribution: Primarily used in conjunction with Vacuum Insulated Pipes (VIPs) and Vacuum Insulated Hoses (VIHs), the Vacuum Insulated Shut-off Valvefacilitates precise control of cryogenic fluids in distribution networks. This allows for efficient routing and isolation of specific areas for maintenance or operation.
- LNG and Industrial Gas Handling: In LNG plants and industrial gas facilities, the Vacuum Insulated Shut-off Valve is crucial for controlling the flow of liquefied gases. Its robust design ensures safe and leak-free operation even at extremely low temperatures. These are a critical piece of cryogenic equipment with wide spread use.
- Aerospace: Used in aerospace applications, the Vacuum Insulated Shut-off Valveprovides essential control over cryogenic propellants in rocket fuel systems. Reliability and leak-tight performance are paramount in these critical applications. The Vacuum Insulated Shut-off Valves are built to precise dimensions, thus improving cryogenic equipmentperformance.
- Medical Cryogenics: In medical devices such as MRI machines, the Vacuum Insulated Shut-off Valve contributes to maintaining the extremely low temperatures required for superconducting magnets. It is typically attached to Vacuum Insulated Pipes (VIPs) or Vacuum Insulated Hoses (VIHs). It can be essential for the reliable operation of life-saving cryogenic equipment.
- Research and Development: Laboratories and research facilities utilize the Vacuum Insulated Shut-off Valve for precise control of cryogenic fluids in experiments and specialized equipment. The Vacuum Insulated Shut-off Valve is often used to direct the cooling power of cryogenic fluids through Vacuum Insulated Pipes (VIPs) towards a sample for study.
The Vacuum Insulated Shut-off Valve is designed to offer superior cryogenic performance, reliability, and ease of operation. Its integration within systems featuring Vacuum Insulated Pipes (VIPs) and Vacuum Insulated Hoses (VIHs) ensures efficient and safe cryogenic fluid management. At HL Cryogenics, we are committed to manufacturing cryogenic equipment of the highest quality.
Vacuum Insulated Shut-off Valve
The Vacuum Insulated Shut-off Valve, also known as a Vacuum Jacketed Shut-off Valve, is a cornerstone of our Vacuum Insulated Valve series, essential for Vacuum Insulated Piping and Vacuum Insulated Hose systems. It provides reliable on/off control for main and branch lines and integrates seamlessly with other valves in the series to enable a range of functions.
In cryogenic fluid transfer, valves are often a major source of heat leak. Traditional insulation on conventional cryogenic valves pales in comparison to vacuum insulation, causing significant losses even in long runs of Vacuum Insulated Piping. Choosing conventionally insulated valves at the ends of a Vacuum Insulated Pipe negates many of the thermal benefits.
The Vacuum Insulated Shut-off Valve addresses this challenge by encasing a high-performance cryogenic valve within a vacuum jacket. This ingenious design minimizes heat ingress, maintaining optimal system efficiency. For streamlined installation, Vacuum Insulated Shut-off Valves can be pre-fabricated with Vacuum Insulated Pipe or Hose, eliminating the need for on-site insulation. Maintenance is simplified through a modular design, allowing seal replacement without compromising the vacuum integrity. The valve itself is a critical piece of modern cryogenic equipment
To accommodate diverse installation requirements, the Vacuum Insulated Shut-off Valve is available with a wide array of connectors and couplings. Custom connector configurations can also be provided to meet specific customer needs. HL Cryogenics is dedicated to only the highest performing cryogenic equipment.
We can create Vacuum Insulated Valves using customer-specified cryogenic valve brands, however, some valve models may not be suitable for vacuum insulation.
