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.…

Relying on the high-tech senior engineering team of RAYS, the wear-resistant ball valve independently developed by RAYS has truly achieved zero leakage and its’ service life has reached the world’s advanced level.Advanced ball and seat hardening technologyIn order to ensure that the valve can adapt to: high, low temperature, and particle conditions; the ball and seat sealing surface of RAYS wear-resistant ball valve adopts advanced sealing surface hardening technology. This includes: supersonic spraying, metallurgical melting spraying, surface envoy hardening, cemented carbide spraying, etc. The surface hardness of supersonic spraying is up to HRC70 in which the coating thickness can reach 0.3mm, and the bonding strength is above 10000PSI. The surface hardness of metallurgical melt spraying is about HRC64 in which the coating thickness can reach 1mm, and the bonding strength is up to 15000PSI. The sealing surface material can withstand high temperature up to 650C and has strong friction & erosion resistance in which it can meet the requirements of various harsh working conditions.Reliable packing sealing structureThe valve stem adopts a V-shaped packing sealing structure. The V-shaped packing can effectively convert the pressing force and medium force of the packing gland into the sealing force of the valve stem. The traditional packing gland is changed to the two-piece structure design of the packing pressure plate and the packing socket. The packing pressure plate & the packing socket adopt spherical contact to ensure that the packing socket is always vertical, and a guide bush is set inside the packing socket to avoid the packing socket galling & wear in which reduces valve operating torque. According to the needs of the working conditions, a butterfly spring-loaded packing pressing mechanism can be used to make the sealing of the valve stem packing more reliable so the valve can still ensure the sealing performance of the valve stem packing after long-term use.Excellent sealing performanceRAYS adopts special ball and valve seat processing equipment combined with the unique ball grinding process through the multi-directional 360-degree rotation of the ball and the grinding tool. Therefore, the ball reaches the specified roundness, smoothness, and 100% matched between the ball & valve seat sealing surface to achieve zero leakage of the sealing.…
