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.
The Insulation Jacket Ball Valve is specially designed for pipeline systems that require maintaining the temperature of the medium. It is made of high-quality stainless steel or carbon steel and combines with precise processing technology to ensure reliable sealing and smooth control under high-temperature and high-pressure conditions. The valve body adopts a jacketed insulation structure and can be filled with steam or heat transfer oil, effectively reducing heat loss. It is suitable for high-temperature fluid transportation systems in industries such as chemical, petroleum, heat supply, and pharmaceuticals. The structure is compact, the opening and closing is rapid, the sealing performance is excellent, and it is an ideal control valve for high-temperature fluid pipelines.
The Axial Flow Check Valve has a unique axial flow design, and its spool is aligned with the flow direction, significantly reducing the resistance loss when the fluid passes through. The spool is driven by spring or fluid pressure for quick opening and closing. When the fluid is flowing forward, the spool is pushed open and the fluid passes smoothly. When the fluid flows in reverse, the spool is quickly closed, effectively preventing backflow, and ensuring the stability and safety of the system operation.
