The high-temperature ball valve is a special type of valve designed for high-temperature and high-pressure environments. It can effectively control the on-off of high-temperature and high-pressure fluids. It can operate stably under harsh conditions and meet the precise control requirements in industrial production processes. It is widely used in the petroleum, chemical, natural gas, and power industries.
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 globe valve is mainly composed of valve body, valve cover, valve disc, valve stem and valve stem nut. The handwheel applies a certain torque on the upper end of the valve stem, and passes the valve stem to the valve petals to move it along the valve stem axis to achieve full or full-closed motion. The force applied by the handwheel can be obsessed with the valve seat to reach the stagnation state. The two-valve petals are designed to enter the top of the medium from the cover of the valve petals. The force force of the medium is the same as the valve closure direction, so the torque of the valve closure is small; The petals, the medium enters the exit of the valve from the inside, and generates a small amount of balance of the pressure of the pressure on both ends of the valve inlet and export, thereby achieving the effect of reduced the valve opening torque. Therefore, globe valve(double disc) is mainly used in high pressure or large-caliber pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.
