RAYS Gas-Over-Oil Actuated Ball Valves Finished For Delivery

Recently, RAYS have successfully completed a DN150-DN1000 PN63 Gas-Over-Oil actuated ball valves project which have passed various tests. After debugging, these 17 pcs of ball valves and actuators have been delivered to our foreign customer in March of 2020 which will be placed in a large-scale booster compressor station project.Due to the recent epidemic situation in China, under the advice of the local epidemic prevention team during early March, RAYS management and personnel department properly arranged the enterprise to resume work and production. RAYS have tried their best to shorten the impact of the delivery date for customers.All the ball valves delivered this time adopted safety Gas-Over-Oil actuator with hydraulic manual and pneumatic functions, which are featured with remote control and ESD emergency shutdown functions. The customer only needs to provide 220V AC power supply on-site. In addition, the challenging characteristics of the products in this order were: large diameter, high pressure, high height of the whole setup, the largest single piece of the DN1000 ball valve weighed about 15 tons, production equipment, lifting equipment, debugging equipment, and personnel safety production. In the early stage of order production RAYS held: production seminars, process seminars, safety production training sessions for personnel, debugging training sessions for executing agencies, and other ways to ensure the smooth progress of the order. Also, RAYS held reasonable time planning and procurement of the corresponding supporting equipment to ensure the production efficiency of the order and the stringent testing requirements of the valves.The products of this order have two different designs of ball valves: bolted body connection and fully welded body. Before installation of the actuator, in order to ensure that the torque of the ball valve is within the theoretical calculation range, there is a need to detect the torque value of the ball valve before the actuator debugging. Fortunately, RAYS is also equipped with a special automated computer torque detector for situations such as this.The excellent quality and high-performance stability of the fully welded ball valve is not achieved by the normal ball valve. Therefore, the service life of the fully welded ball valve far exceeds the normal ball valve. In this instance, it is used very widely in various fields such as: urban gas, urban heating, petrochemical, ship-building, steel, pressure control station, power plant, and other types of pipeline equipment. Fully welded ball valves can be: long-term, stable operation, easy installation, lower cost of the expenditure, etc. In the foreseeable future, the fully welding process will become a trend in valve manufacturing.For more information, please visit http://old.raysvalve.com/, or send an email to info@raysvalve.com…

RAYS XL sized Fully Welded Ball Valves finished for delivery

Recently, RAYS have successfully completed 14 pcs of fully-welded ball valves with specifications of DN1200 PN16 which have passed various tests. They will be delivered to an international customer and put into use within a large-scale natural gas project. Such a large sized valve can be called a “giant valve”. Valve companies rarely produce such large sized full welded ball valves. Therefore, this was also the first time for us, here at RAYS, to manufacture such a large size. We used a serious and rigorous attitude into each process which we invested 100 percent of the effort, and the final product resulted in our favor - RAYS extra-large sized fully welded ball valves finished for delivery successfully. Technical features of fully welded ball valves:Due to the ball valve adopting a fully-welded structure, the overall leakage point is very little which greatly reduces the risk of leakage.Compact structure & easy for installation.Special flux is used in welding with fine granularity and good slag removal which can meet the high strength & toughness of weld metal performance.With fire-safe & anti-static device which are safer and more reliable.The buried type ball valves can be directly buried into the ground, no need to build a tall valve well, only set up small shallow well on the ground, and greatly saves construction costs and engineering time.Body length and stem height can be adjusted according to pipe construction & design requirements.The machining precision of the sphere is very precise and easy to operate.With our customer’s request, the driving device includes: lever, worm gear, electric, pneumatic, pneumatic-hydraulic, electro-hydraulic, etc. The excellent quality and high-performance stability of the fully welded ball valve is not achieved by the normal ball valve. Therefore, the service life of the fully welded ball valve far exceeds the normal ball valve, so it is used very widely in various fields such as: urban gas, urban heating, petrochemical, shipbuilding, steel, pressure control station, power plant, and other types of pipeline equipment. Fully welded ball valves can be: long-term, stable operation, easy installation, lower cost of the expenditure, etc. In the foreseeable future, the fully welding process will become a trend in valve manufacturing.

RAYS large sized and middle to high pressure Fully Welded Ball Valves finished for Delivery

Recently,RAYS have successfully completed four pcs of fully-welded ball valves withspecifications of 32" CL600 and 40" CL600, which had passed varioustests and finished painting. They will be delivered to an internationalcustomer later this month and put into use within a large-scale natural gasproject. Due to the ball valve adoptinga fully-welded structure, the overall leakage point is very little whichgreatly reduces the risk of leakage.The valve stem is designed forblowout prevention to prevent the valve stem from ejecting from the valve bodydue to improper operation.Fully-welded ball valve alsohas a fire and anti-static device.In order to drain the ballvalve, the drain valve and vent valve are respectively installed on the valvebody. Then the isolation valve or special discharge joint is adopted, which is saferand more reliable. Inconclusion, compared with ordinary ball valves, fully-welded ball valves havehigher safety performance. Fully-welded ball valves can also be equipped with a connecting padof various drive devices. The driving device includes lever, worm gear,electric, pneumatic, pneumatic-hydraulic, electro-hydraulic, etc. 尺寸SizeDN50-DN1400 NPS 2” ~ NPS 56”压力Pressure RatingPN20-PN420 Class 150LB—Class 2500LB材料MaterialWCB、LCB、CF8、CF8M、CF3、CF3M、A105、LF2、F304、F316、F304L、F316L设计制造标准Design standardAPI608、API 6D 、BS5351、ASME B16.34、GB/T12237、GB/T15672结构长度Face to FaceASME B16.10、GB/T12221、API 6D连接标准End ConnectionASME B16.5、ASME B16.47、ASME B16.25、GB/T9113、JB/T79、HG/T70592压力测试标准Test and InspectionAPI 6D 、API 598、GB/T13927、GB/T26480操作方式Operation Method手柄、蜗轮、电动、气动、气液联电动等lever, worm gear, electric, pneumatic, pneumatic-hydraulic, electro-hydraulic For more information, please visit http://www.raysvalve.cn/, or send an email to info@raysvalve.com, or call +86-577-66999000 …
