What Is Hanno Low Temperature Gate Valve?

A Hanno low temperature gate valve is a specially engineered industrial valve designed for controlling the flow of cryogenic or low-temperature fluids. These valves are manufactured to operate effectively in environments where temperatures can drop below -46°C and even reach cryogenic ranges such as -196°C.

Unlike standard valves, cryogenic gate valves require unique structural designs and material treatments to maintain sealing integrity and mechanical stability under thermal stress.

• Designed for LNG and cryogenic systems
• Excellent sealing performance
• High corrosion resistance
• Reliable under extreme low temperatures
• Long service life with minimal maintenance

Hanno focuses on producing industrial valves that comply with international standards while ensuring safe operation in demanding industrial conditions.

How Does a Low Temperature Gate Valve Work?

The working principle of a low temperature gate valve is similar to conventional gate valves. A gate or wedge moves vertically to open or close the fluid passage.

When the valve stem rotates:

• The gate rises to allow fluid flow
• The gate lowers to block the flow completely
• Bidirectional sealing prevents leakage
• Extended bonnet design protects stem packing from freezing

Cryogenic valves from Hanno are specifically designed with extended bonnets to reduce heat transfer and protect sensitive sealing components from extremely low temperatures.

Key Features of Hanno Low Temperature Gate Valves

Hanno valves are recognized for their advanced engineering and superior manufacturing quality. Below are some of the major features that make them suitable for industrial cryogenic applications.

1. Extended Bonnet Structure

The extended bonnet design minimizes temperature transfer from cryogenic media to external components, helping maintain operational reliability.

2. High-Quality Sealing Performance

Hanno uses precision-machined sealing surfaces and advanced seat materials to achieve tight shutoff performance.

3. Cryogenic Material Compatibility

Special stainless steels and low-temperature alloys maintain toughness and strength under cryogenic conditions.

4. Fire-Safe Design

Many Hanno valve models include fire-safe structures for improved operational safety in hazardous industrial environments.

5. Corrosion Resistance

The valves resist corrosion from chemicals, LNG, liquefied gases, and harsh industrial media.

Material Selection for Cryogenic Performance

Material selection is one of the most important factors in low temperature valve manufacturing. Poor material choices can lead to brittleness and structural failure.

Hanno carefully selects certified materials that comply with international low-temperature testing standards.
