1. Ultra-low temperature performance: Through deep cold treatment technology, the valve ensures reliable sealing within the temperature range of -100℃, without the risk of brittleness.
2. Side-mounted design: The valve cover is installed sideways, eliminating the need to dismantle the pipeline during maintenance, significantly reducing maintenance costs and downtime.
3. Dual sealing guarantee: Using a combination of metal hard seal and soft seal, it has strong anti-wear properties and achieves zero leakage in both directions.
4. Anti-frosting structure: The elongated valve stem design and low-temperature insulation protection effectively reduce heat conduction and prevent external frosting.
5. Lightweight and high-strength: Optimizing the valve body structure, it reduces weight while ensuring the pressure-bearing capacity, facilitating installation and transportation.
6. Wide applicability: Compliant with international standards such asAPI 6D、 BS6364 and ISO28921, suitable for high-end fields such as LNG storage and transportation, and chemical industries.

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 Power Plant Gate Valve is mainly suitable for the pipelines of various systems of thermal power station, cutting or connecting the pipeline medium. Compared with other valve products, the Power Plant Gate Valve is characterized by high temperature and high pressure. It is counted as a unique and closely sealed structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The Power Plant Gate Valve has the design characteristics of ordinary wedge-type gate valves. The valve body has a guide mechanism to prevent rotation when the gate is turned on or closed to ensure that the seal of the gate on the valve seat is correspondingly accurate. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
RAYS pig valve is a high-performance ball valve designed for severe industrial environments, featuring multifunctionality aimed at optimizing pipeline cleaning and maintenance. This valve facilitates the movement of pipeline pigs to effectively remove scale, deposits, and other impurities, maintaining cleanliness and flow efficiency in pipelines.
