Recently, RAYS successfully delivered a batch of high-quality rising stem ball valves, totalling 60 units, designed explicitly for hydrogen. This accomplishment showcases RAYS’ outstanding production capabilities and R&D prowess. These rising stem ball valves have nominal diameters ranging from NPS 1” to 16”, with pressure classes from CL 300 to 1500. They feature a top-entry design that ensures durability and excellent sealing performance.The order includes two 16” 1500lb rising stem ball valves, notable for their large size and high pressure. These valves are suitable for high-pressure and high-flow conditions, reflecting RAYS’ expertise in manufacturing large-size, high-pressure valves.Hydrogen energy is a clean energy source that is environmentally friendly and economically viable. However, it also imposes high demands on the safety and reliability of valve products. RAYS manufactures valve products strictly according to the international API 6D standard. The materials and structure of this batch of rising stem ball valves have been carefully selected and tested, utilizing A105 and A216 WCB carbon steel with unique chemical compositions to ensure stable performance and long-term durability under hydrogen conditions.As the global demand for clean energy, particularly hydrogen energy, continues to grow, RAYS is committed to advancing technological innovation and providing high-standard valve products to contribute to a green and sustainable future.Product: Rising Stem Ball ValveMaterial: A105, A216 WCB Carbon SteelNominal Size: NPS 1″～16″Pressure Rate: CL300~1500Temperature Range: -29C～+350COperator: Handwheel, GearApplication Range: Suitable for hydrogen…

Triple Offset Metal Seated Butterfly ValveTriple Offset Butterfly Seated Valves are a type of high-performance butterfly valve, also known as triple eccentric metal-seated butterfly valves. These valves are designed with a triple offset structure that provides tight sealing characteristics, making them excellent for high-pressure and high-temperature applications. Technical ParametersProduct Type: Triple Offset Metal Seated Butterfly ValveSize Range: DN50-DN1200 or 2″-48″Pressure Rating: From 150LB to 2500LBOperating Temperature: From -196C to 650CConnection Type:RF, BW, LUG,WaferMaterial: Carbon steel (such as WCB), stainless steel (such as CF8/CF8M), alloys (such as Monel), duplex steel, etc.Suitable Medium:Butterfly Valves are designed to control fluid types such as water, oil, gas, steam, etcOperation Mode: Handle, turbine, gas-hydraulic linkage, electric, pneumatic, electro-hydraulic linkage, etc Product FeaturesGood sealing performance: Due to their eccentric design, when the valve is closed, the disc can tightly fit against the seat, achieving metal-to-metal sealing and minimizing leakage.High temperature and pressure tolerance: Metal sealing components enable triple offset butterfly valves to withstand higher temperatures and pressures, making them more durable than ordinary rubber or PTFE sealed butterfly valves.Longevity and low maintenance costs: Reduced friction means less wear and tear, leading to an extended service life and lower maintenance costs. The three “offsets” implication:First offset: The disc is offset from the shaft axis, which allows for reduced friction between the disc and the seal during opening.Second offset: The shaft axis is offset from the pipe centerline, which further reduces friction and wear between the sealing surfaces.Third offset: The centerline of the sealing surface is offset, often with the disc sealing surface and seat sealing surface being conical. This conical configuration allows for a tighter seal upon closure. Because of these characteristics, triple offset butterfly valves are very popular in critical processes within industries such as oil and gas, chemical, heating, and water treatment.…

RAYS recently delivered high pressure and high temperature gate valves and check valve for the project based in Malaysia.The middle cavity of the valve adopts a pressure self-tightening sealing structure. The higher the inner cavity pressure, the better the sealing performance. Both ends of the branch pipe are welded structures, which are suitable for different connection requirements.The sealing surfaces of the gate and valve seat are made of stellite cobalt-based cemented carbide, which has: good wear resistance, high temperature resistance, corrosion resistance and scratch resistance.The valve stem is quenched, tempered and surface nitride. This creates good corrosion resistance and scratch resistance. The structure of the opening and closing parts can be designed into different forms such as single board, double board, parallel double board and so on according to user requirements.The gate valve connected by welding is suitable for cutting off or connecting the medium on the pipeline of various working conditions such as petroleum, chemical industry, thermal power station, etc. This is with a nominal pressure of 16.0-32.0Mpa and a working temperature of 540 C.…

The power plant valves supplied by RAYS to a supercritical power plant phase Ⅱ in Thailand have been successfully delivered.Prior to this project, the Thailand power plant owners all used European imported power plant valves for the key position of supercritical high temperature and high pressure. However, after many technical exchanges/product design ideas and quality tracking control norms, and the high quality valves supply in the last two years at the phase Ⅰ, a power plant owner has full confidence and trust in our power plant valves for harsh conditions with the design/manufacture/quality control. Background/Condition of the Power Plant Valve ProjectThe power station project is located in a power station unit on a famous tourist holiday island in Thailand. The project code is “SKIC TG18”, and the EPC contractor is “SCG”. The medium is high-temperature & high-pressure steam, and the highest pressure reaches 100 Bar (10 MPa) when the temperature of steam reaches 510℃.Order Specifications of the Power Plant ValvePower plant pressure seal electric gate valve, size & pressure are 12″ & 1500LB, main material is F91, adopt ROTORK actuator imported from EuropePower Plant Valve Design CharacteristicsOne-piece forged F91 body and the design life of 25 years. Strict quality control, screening out high-quality forging suppliers, raw materials and machining process inspection stage through PMI element composition analysis, RT, PT, and other non-destructive testing procedures to strictly control the quality of pressure contain parts. In addition, during the machining process, the quality and technics can be traced for all sizes.Testing RequirementsDuring the final finished product testing, SGS as the third party inspection was invited to witness the dimension and pressure testing. The qualified rate of finished products was 100%, and the products were shipped & delivered to the owners successfully. Introduction to Power Plant ValvePower plant valve is also called the special valve for the power plant. It is mainly used for cutting off or connecting the pipeline medium in various systems of the thermal power station. Applicable medium: water, steam, and other non-corrosive media. Compared with other valves, the power plant valve is characterized by high temperature & high pressure, unique pressure seal design, and the higher the pressure, the more reliable the sealing. Due to the special performance with technical characteristics and working conditions, the power plant valves have special characteristics which other products can’t replace.Structural Advantages of Power Plant Valve1. Pressure seal is adopted and both ends of branch pipe for valve body have welded connection.2. The valve seat & disc sealing surface are made of cobalt-based hard alloy plasma spray welding and with good wear resistance & abrasion resistance.3. The valve stem is made of special material which is treated by a special process and has good corrosion resistance along with scratch resistance.…
