**Low-Temperature Shut-Off Valve Description:**
A low-temperature shut-off valve is a type of valve where the closing element (valve disc) moves along the centerline of the valve. Depending on the movement of the disc, the opening of the valve seat changes proportionally with the stroke of the disc. This design allows for precise control and regulation of flow, making it ideal for both shut-off and throttling applications.
**Key Features:**
- Compared to simpler valves, this design offers easier manufacturing and maintenance.
- The sealing surfaces are less prone to wear and abrasion, ensuring good sealing performance.
- During operation, there is no relative sliding between the valve disc and the valve body sealing surface, which reduces wear and enhances longevity.
- The valve has a relatively short stem stroke, resulting in a compact height compared to gate valves, although the overall structure may be longer.
- Opening and closing requires more effort due to higher torque requirements, and the process takes more time.
- There is significant fluid resistance because the flow path is more tortuous, leading to increased power consumption.
- For nominal pressures up to PN≤16MPa, the medium typically flows from below the valve disc upward. For higher pressures (PN≥20MPa), the flow direction is usually reversed, moving downward from the disc to improve sealing.
- It is important to note that the medium can only flow in one direction when using a globe valve, and the flow direction cannot be changed during operation.
- When fully open, the valve may experience some erosion depending on the media and operating conditions.

This valve is widely used in industrial settings, especially where reliable shut-off and accurate flow control are required. Its durable construction and efficient performance make it a preferred choice in cryogenic and high-pressure environments.
Tungsten Alloy Blank
A tungsten alloy blank is a piece of material made from a mixture of tungsten and other metals, such as nickel, iron, or copper. Tungsten alloys are known for their high density, strength, and resistance to corrosion and wear. These blanks can be used to create a variety of products, including bullets, weights for fishing or hunting, radiation shields, and aerospace components. The blanks are typically produced through a process of powder metallurgy, where the tungsten and other metals are mixed together, pressed into a mold, and then sintered at high temperatures to create a solid piece of material.
