High pressure cryogenic ball valve

Product Description:

The High Pressure Cryogenic Ball Valve is designed for extreme temperature and high pressure applications where safety, durability, and performance are critical. It is used in systems that require the control of fluids or gases at cryogenic conditions (temperatures as low as -196°C) while maintaining high pressure (up to 4500 psi). These valves are commonly used in industries such as liquefied natural gas (LNG) production, liquefied petroleum gas (LPG) storage, chemical processing, and oil and gas pipelines. These valves feature a trunnion mounted ball design and superior sealing technology to ensure optimal functionality in critical cryogenic environments.

The Cryogenic Ball Valve is designed to prevent leaks, provide a tight shutoff, and maintain the structural integrity of the valve at low temperatures and high pressures. Made from high-strength materials, including stainless steel and carbon steel, these valves feature advanced insulation and specialized seals to prevent damage and ensure long-term reliability.

Product Features:

Cryogenic Performance: High-Pressure Cryogenic Ball Valves are designed to withstand extremely low temperatures down to -196°C, typical for LNG applications. The valves are designed to prevent thermal contraction or expansion, maintaining stable performance and reliable shutoff at cryogenic temperatures.

Trunnion-Mounted Ball Design: Trunnion-mounted balls are used to ensure more stable operation at high pressures. Unlike floating ball valves, the trunnion-mounted design provides better support for the ball, preventing deformation at high pressures and ensuring a tighter seal in demanding conditions.

Zero Leakage: The valve’s advanced sealing technology, including graphite seals, PTFE (polytetrafluoroethylene) seat rings, and Viton O-rings, enables zero leakage performance, which is critical for cryogenic systems where leaks can cause operational failures or safety risks.

Durable Construction: Made from high-quality materials such as stainless steel and carbon steel, these valves are built to withstand extreme conditions. These materials resist corrosion, wear, and fatigue, ensuring long-term durability and reliable operation.

Manual, pneumatic or electric actuation: Cryogenic ball valves can be equipped with a variety of actuation options, including manual, pneumatic or electric actuators, allowing remote control, automatic operation or manual closure, depending on the specific system requirements.

Compact and reliable: The compact design of the cryogenic ball valve makes it easy to install in tight spaces, especially in high-density piping systems, while still providing a reliable, tight seal under high-pressure and low-temperature conditions.

Advantages

Reliability in Cryogenic Applications: Designed for cryogenic temperatures, these valves ensure optimal performance in LNG and LPG systems where other valves may fail due to freezing or thermal expansion.

High Pressure Resistance: Rugged construction and design make these valves ideal for high pressure environments. They ensure fluid or gas flow is safely controlled even in systems operating at extreme pressures, reducing the risk of valve failure.

Safety: With zero-leakage performance and advanced sealing technology, these valves help prevent dangerous leaks of cryogenic fluids, improving the safety of the system and its operators.

Low Maintenance: Designed for reduced wear, these valves have a long service life and require less maintenance than valves not designed for cryogenic applications. The use of durable materials and self-lubricating seals ensures long-term reliability.

Versatile Actuation Options: The valves are able to support different actuation options (manual, pneumatic and electric), allowing for more flexible integration into automated or manual systems, reducing operating costs and improving overall system efficiency.

Enhanced Performance in Extreme Conditions: The valves’ thermal insulation properties combined with advanced sealing materials ensure they remain effective even in rapidly changing or extreme temperature and pressure conditions, providing consistent performance.

Long-Term Durability: High-strength materials and superior construction quality ensure these valves can withstand harsh environments for long periods of time, minimizing the need for replacement and reducing downtime.
