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' Double Disc Gate Valve-Ethylene is manufactured using high-strength, high-temperature resistant materials, specifically designed for handling cracked gases in the petrochemical industry. This valve features exceptional sealing capabilities and low maintenance requirements, effectively handling high temperatures and corrosive media. Its unique slab gate design ensures smooth fluid flow without any obstruction, thereby reducing pressure loss and enhancing system efficiency. Additionally, the valve is equipped with an automatic self-cleaning feature that removes deposits during operation, ensuring reliability and stability over long-term use. Ideal for both new projects and upgrades of existing systems, the RAYS Double Disc Slab Gate Valve-Ethylene is a perfect choice for enhancing productivity and safety.
The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of forged steel stop valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel stop valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and their sealing performance is much better than that of cast steel stop valves, and their service life is longer. Like other stop valves, they are subject to the restrictions of the flow direction of the medium. Forged steel stop valves can be divided into straight-through stop valves (type stop valves) and direct-flow stop valves (Y-type stop valves) according to installation positions.
