Valves are an important part of the equipment manufacturing industry. They are indispensable fluid control equipment for pressure-bearing special equipment boilers, pressure vessels and pressure pipes. They are widely applied in: petroleum, chemical, power, long-distance pipelines, shipbuilding, nuclear industry, aerospace, onshore & offshore oil recovery, and other fields.   With the development of cryogenic technology – liquid helium (LHe), liquid hydrogen (LH2), liquid nitrogen (LN2), liquid oxygen (LO2) and liquefied natural gas (LNG) are evolving in the fields of nuclear…

The performance test of the #cryogenic valves are carrying out inside the RAYS factory. The valves were cooled down to -196 °C with liquid nitrogen, and the body was filled helium gas and the shell leak test was performed using a Helium Leak Detector.  …

Recently, RAYS had sets of DN150/PN100 and DN300/PN150 carbon steel pneumatic hydraulic actuated Ball Valves which have been completed for production. They successfully passed the inspection and will be delivered to an international customer for their use in their natural gas pipeline. The pneumatic hydraulic ball valve is widely used in long distance natural gas pipelines and Oil & Gas field ring trunk pipe networks. They have the advantages of: stable transmission, easy control, and no need of power supply.…

RAYS Cryogenic Ball Valves are mainly used in liquefied natural gas, liquefied petroleum gas installations, air separation devices, and other low-temperature industries. The most advanced Lip-Seal sealing technology is adopted by RAYS Cryogenic Ball Valve, which can maintain excellent sealing performance in application. For the ball valves which are commonly used in low temperatures, RAYS fully considers the requirements of various parts of the valve under low temperature conditions. Due to the temperature stress of the valve body under low…

Recently, RAYS sets of 20″ 600LB and 24″ 600LB fully-forged buried top entry ball valves have been successfully produced in the factory, and will be delivered in May 2018 to our international customer for use in a large Gas project. Top Entry Ball Valves are widely used in: petroleum & natural gas pipelines, oil extraction, oil refining, petrochemical, chemical, chemical fiber, metallurgy, electric power, and nuclear power plants. The biggest difference between top entry ball valve vs. the ordinary ball…

On March 21, 2018, RAYS Valve was completing a fire test with the Quality Supervision Bureau. Valve fire test is the test of simulating a valve in an actual fire environment, which can reflect the fire resistance of the valve. The fire resistance of the valve is the ability of the valve to keep working normally in a high temperature flame. It is an important indicator for the safety performance of the valve. Picture of a Valve after the fire…
