Recently, RAYS successfully delivered a batch of pneumatic ball valves to an international customer. This project will transport liquefied natural gas along the Northern Sea Route. To adapt to the harsh Arctic weather, these pneumatic ball valves are not only capable of stable operation in Cryogenic environments but also come with customized pneumatic actuators for quick opening and closing.

Given the flammable and explosive nature of liquefied natural gas, in order to meet customer demands and ensure equipment safety during the design and production process, RAYS’ pneumatic ball valve is designed with a drip tray on the extended bonnet of the cryogenic ball valve. The drip tray is installed on the outside of the insulation layer to prevent condensed water from dripping onto the insulation layer and the upper part of the valve body, thereby protecting the insulation layer and preventing cold energy loss.

Additionally, fireproof design and anti-static design are particularly important. The RAYS’ pneumatic ball valve uses graphite seals in various sealing parts to meet fireproof requirements and adopts a spring-loaded conductive structure to prevent the accumulation of static charges, which could lead to explosion hazards. When the valve cavity pressure exceeds the set pressure and the cavity pressure is abnormal, the valve seat will slightly move away from the surface of the ball to release the excessive cavity pressure into the channel.

This batch of Cryogenic pneumatic ball valves can operate stably within a temperature range of -120°C to +60°C. Each component, after cryogenic treatment, meets the relevant standards. They have performed excellently in Cryogenic tests and high-pressure gas tests, and inspection reports can be provided. They meet the customer’s quality requirements.

The RAYS team closely collaborates with customers throughout the entire order process while providing customized technical support & solutions and offering after-sales quality assurance services to ensure that the products meet international standards & customer requirements. This is all while being safe and effective in practical applications.

In the future, RAYS will continue to conduct research and development in the field of liquefied natural gas and gain an in-depth understanding of customer needs. RAYS will continuously drive the progress of industrial valve technology while providing efficient and reliable solutions for various demanding industrial applications!
