Four Eccentric Butterfly Valve as New Type Butterfly Valve

Recently, Zhengzhou Jinggong Technology Co., LTD. (ZZJG VALVE), headquartered in Zhengzhou City, Henan Province, has launched a new type of valve - the four eccentric butterfly valve, providing reliable zero-leakage conditions and lower torque opening and closing for industries such as LNG and petrochemicals. It offers its own solution to this long-standing problem that has plagued the industry for many years.

This new type of valve has been specially developed for the harsh working conditions of various industries, aiming to provide reliable, zero-leakage performance and a longer operating life.

The development of this butterfly valve is aimed at addressing long-standing leakage and corrosiveness issues in fields such as liquefied natural gas (LNG), petrochemicals, and aerospace, where traditional valves often have performance limitations. The four-offset design provides a solution for scenarios with extreme temperatures, high pressures, and those requiring absolute sealing integrity.

"Our goal in developing this valve is to design one that can eliminate common failure points and inefficiency issues in major industrial fields," said the chief engineer of ZZJG VALVE. This technology has brought about visible improvements, ensuring operational safety and will definitely reduce the operating costs for our customers.

The main technical features of this four-offset butterfly valve are as follows:

1. Wider temperature range
This valve can operate within an extremely wide temperature range, from low-temperature conditions of -196°C (-320°F) to ultra-high-temperature processes up to +1100°C (2012°F). This range covers the area that typically requires multiple specialized valves to meet, thereby simplifying the inventory management and system design for operators.

2. Verifiable zero leakage
This valve design focuses on achieving physically verifiable zero leakage. Through precise processing, the contour tolerance of its sealing surface is only 0.0004 inches, the surface finish is close to mirror finish, and the roughness is only Ra 0.156 μm. This level of precision is particularly important for handling leakage situations when dealing with hazardous fluids.

3. Reduce operating costs
Compared with the industry-standard three-eccentric valve, the operating torque of this valve has been reduced by more than 30%, which is a significant engineering advancement. The CAM design and frictionless geometry among them allow for the selection of smaller and more energy-efficient actuators, directly reducing cost expenditure and operational complexity.

This type of valve can also simplify the operation process. Its sealing ring is designed to simplify installation, thereby reducing the risk of human error during the replacement process. In addition, the ingenious design of the core components can prevent accidental damage to the sealing surface during assembly. This simplified installation and disassembly design significantly reduces the average repair time and directly enhances the operational profitability of the factory.

This valve can solve key problems in the industry such as
Liquefied natural gas (LNG) : It provides reliable sealing for cryogenic media throughout the system, minimizing dangerous leaks and costly evaporation losses during transportation and storage.

Petrochemicals and oil refining: Provide durable and long-term performance in high-temperature catalytic cracking units, significantly reducing fugitive emissions and maintenance cycles.

Aerospace and defense: Meeting the strict requirements for lightweight and high reliability of propulsion systems and ground support equipment under extreme thermal conditions.

Nuclear energy: Meeting the strict requirements for safety and reliability in nuclear-grade applications, ensuring zero failure in critical systems related to power plant safety.
