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.…
