CHM703 High Pressure Control Valve is a high-precision fluid control device specially designed for harsh industrial environments. It is suitable for high-pressure pipeline systems in industries such as petroleum, chemical engineering, power, and metallurgy. This product uses high-quality materials and advanced manufacturing techniques to ensure stable operation even under extreme conditions such as high pressure, high temperature, and strong corrosion. Its compact structure and reliable sealing enable precise regulation of flow and pressure, meeting the strict requirements of complex industrial processes. The high-pressure regulating valve has excellent shock resistance and vibration resistance, and is suitable for frequent opening and closing and high-load operation environments. It is also easy to maintain, effectively reducing long-term usage costs, making it an ideal choice in the field of industrial fluid control.
Expanding Slab Gate Valve is a type of slide valve that utilizes parallel gate plates as its closing mechanism. These plates are equipped with a spreading mechanism to enhance functionality. The force pressing the plates against the valve seat is regulated by the medium pressure acting on either a floating gate plate or a floating valve seat. In dual gate flat gate valves, the inter-plate spreading mechanism provides additional pressing force. This valve is designed with innovative features including low operating torque, rapid actuation, minimal vibration, extended operational life, and enhanced safety. It is mainly used for the isolation or venting of gases and liquids in pipeline systems.
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.
