High Pressure Cryogenic Ball Valve

Product Overview

The high-pressure cryogenic ball valve is designed for extreme temperature and high-pressure applications where safety, durability, and performance are critical. It is suitable for systems that need to control fluids or gases at low temperatures (down to -196°C) while maintaining high pressures (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 utilize a trunnion-mounted ball design and superior sealing technology to ensure optimum performance in critical low-temperature environments.

Cryogenic ball valves are designed to prevent leakage, provide tight shutoff, and maintain the structural integrity of the valve at low temperatures and high pressures. These valves are constructed of high-strength materials, including stainless steel and carbon steel, with 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, which is common in liquefied natural gas (LNG) applications. These valves are designed to prevent thermal contraction or expansion to maintain consistent performance and reliable shutoff at low temperatures.

Trunnion-mounted ball valve design: Trunnion-mounted ball valves ensure more stable operation under high pressure. Unlike floating ball valves, the trunnion-mounted design provides better support for the ball valve, prevents distortion under high pressure, and ensures a tighter seal under severe conditions.

Zero Leakage: The valve utilizes advanced sealing technology, including graphite seals, PTFE (polytetrafluoroethylene) seat rings, and Viton o-rings, to achieve zero-leakage performance, which is critical for cryogenic systems where leakage could result in operational failures or safety risks.

DURABLE CONSTRUCTION: These valves are made of high quality materials such as stainless steel and carbon steel to withstand extreme conditions. These materials are resistant to corrosion, abrasion, 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 for remote control, automatic operation or manual shutoff depending on specific system requirements.

COMPACT AND RELIABLE: Cryogenic ball valves feature a compact design that makes them easy to install in tight spaces, especially in high-density piping systems, while still providing a reliable, tight seal under high-pressure, low-temperature conditions.

Product Advantages

Reliability in cryogenic applications: Designed for cryogenic environments, these valves ensure optimal performance in liquefied natural gas (LNG) and liquefied petroleum gas (LPG) systems, where other valves may fail due to freezing or thermal expansion.

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

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

Low Maintenance: Designed to minimize wear and tear, these valves provide long service life and require less maintenance than valves designed for non-cryogenic applications. The use of durable materials and self-lubricating seals ensures long-term reliability.

Multiple actuation options: These valves can support different actuation options (manual, pneumatic and electric), allowing for more flexible integration into automatic or manual systems, reducing operating costs and increasing overall system efficiency.

Superior performance in extreme conditions: The valve's thermal insulation, combined with advanced sealing materials, ensures that it remains effective even under rapidly changing or extreme temperature and pressure conditions, providing consistent performance.

Long-term durability: High-strength materials and superior build quality ensure that these valves can withstand harsh environments for long periods of time, minimizing replacement needs and reducing downtime.
