RAYS' rising stem ball valve is designed to operate without friction between the ball and the seat during opening and to achieve zero leakage when closed. This makes it well-suited for demanding conditions. The valve is made entirely of metal and is fire-resistant, capable of functioning in extreme temperatures ranging from -196°C (320.8°F) to 538°C (1000.4°F). It can handle media with particulates like sand and short fibers, and meets NACE standards for corrosion resistance, ensuring it can resist sulfide stress cracking in harsh environments. The valve also features a self-cleaning mechanism. When the ball is tilted away from the seat, the fluid flows 360° around the ball's sealing surface, effectively removing any debris. This prevents damage from high-speed fluid flows and keeps the sealing area clean. The rising stem ball valve is ideal for various applications including exhaust, fluid transfer, pipeline isolation, bypass, product segmentation, and emergency shutdowns, particularly where high switching frequencies and zero leakage in high temperatures are required.
The working principle of the three eccentric butterfly valve is based on its unique structural design, which achieves sealing and flow control functions through three eccentric distances: Structural Design: Three Eccentric Structure: The valve stem axis deviates from the center of the butterfly plate and the body center, and the rotation axis of the valve seat is at an angle to the axis of the valve body channel. This design enables the butterfly plate to form a wedge-shaped space with the valve seat when closed, achieving sealing through friction. Conical Sealing Surface: The periphery of the butterfly plate is machined into an external inclined conical surface, and the valve seat is an internal inclined conical surface, forming an elliptical contact surface. When closed, the butterfly plate achieves sealing through the asymmetric pressing force in the up and down directions, and the sealing becomes tighter as the pressure increases. Working Mechanism: Open State: The butterfly plate is separated from the valve seat, and the fluid passes through the channel; due to the eccentric design, during the opening process, the butterfly plate gradually detaches from the valve seat, reducing friction and operating torque. Closed State: The butterfly plate rotates 90° to contact the valve seat, forming a wedge-shaped space and achieving sealing through torque. Flow Regulation: During the opening rotation of the butterfly plate, the valve's flow area gradually increases, reducing fluid resistance and improving the flow coefficient, achieving flow regulation. Technical Advantages: Sealing Performance: The metal-to-metal hard sealing method can still maintain good sealing performance in high-temperature and high-pressure environments; Low Friction Operation: The eccentric design significantly reduces the operating torque and extends the valve's lifespan; Self-Locking Function: When closed, the butterfly plate becomes tighter under pressure, preventing the phenomenon of over-positioning. This valve is widely used in the petroleum, chemical, and power industries, and common structural connection forms include double flange type, welding type, lug type, and socket type, etc.
The self-regulating control valve is an energy-saving control device that does not require external driving energy. It relies on the pressure or temperature of the medium being regulated as its power source, automatically adjusting according to set values based on changes in the medium. This valve integrates multiple functions of detection and control into one unit, forming an independent instrument control system. The self-operated control valve adopts a standard modular design. Our products are characterized by: standardization, serialization, and generalization. This achieves a high level of these three aspects. The components of the self-operated pressure regulator and differential pressure regulator are interchangeable. If the control conditions change, the spring & diaphragm components can be easily replaced. The accuracy of the self-operated control valve surpasses that of similar products, and it also offers high stability.
