The main products of this company are Bronze valves, API/DIN gate/globe/ check valves/butterfly valve/plug valve, ball valves and forged steel valves. Its products have been widely used in petroleum, petrochemical, chemical, metallurgy, electric power, water conservancy, machinery and many other fields.
Slab Gate Valve, as a core component in the industrial pipeline system, plays the role of a "hard-core switch". Its working principle is based on the up and down sliding of a stainless steel plate, which can quickly cut off or release the flow of oil and harmful fluids to achieve efficient control.
Did you know? Among those silver-shining pipeline valves in the factory, there is a tough guy called wedge gate valve. It is like the "door god" of the industrial world. It can make dangerous liquids obedient by moving up and down with a blade-shaped metal gate plate16.
Did you know? Those stainless steel gate valves that work silently in chemical plants and oil pipelines are like the "switch masters" of industrial systems. They can accurately control the flow of various liquids and gases by moving a metal gate up and down14.
Forged stainless steel gate valves, an important equipment in the modern industrial field, have become the core components of fluid control systems in many key industries with their excellent corrosion resistance, high strength and unparalleled reliability. From petrochemicals to water treatment, to energy production, forged stainless steel gate valves are everywhere. They silently guard the safe operation of pipeline systems and ensure the stability and efficiency of industrial production.
Special alloy gate valves are made of high-performance materials such as Hastelloy, Monel or GH2130 high-temperature alloy, which have excellent corrosion resistance and can effectively resist chemical erosion by strong acid and strong alkali media (such as hydrogen sulfide and high concentration of chloride ions). These alloys can still maintain stable mechanical properties under high temperature environment (over 800°C), and the wear resistance of the sealing surface is further enhanced by surface surfacing of hard alloy or anodizing. The valve body design adopts a wedge-shaped double gate structure, and linear opening and closing is achieved through pneumatic actuator drive, supporting two states of fully open and fully closed.
Pressure Seal Gate Valve plays an indispensable role in the industrial field. It is widely used in various pipeline systems, mainly used to control the flow of fluids and achieve sealing functions. The design, manufacture and application of this equipment involve complex mechanical engineering knowledge and strict standards and specifications, which are essential to ensure the safe and stable operation of related production processes.
In modern industry, precise and efficient control of fluid flow is the key to improving production efficiency and ensuring safe operation. As the core component of this demand, cryogenic gate valves are widely used in important industries such as petroleum, chemical industry and liquefied natural gas. These valves not only need to maintain stable performance at extreme temperatures, but also have excellent sealing and reliability. With the continuous advancement of technology, the innovation and optimization of cryogenic gate valves have become an important direction for the development of the industry. This article will explore the importance of this key equipment and its application in various industrial fields, and analyze its technical details, design challenges and future development trends.
At Dalian LNG receiving station, engineers are doing a "physical examination" on a silver valve. The surface of Low Temperature Gate Valves">Low Temperature Gate Valves is covered with white frost, like a Coke can just taken out of the refrigerator. Technician Xiao Wang explained while recording data: "This low-temperature gate valve must withstand liquid nitrogen at minus 196 degrees. You can see the metal tube extending from its neck here, which is used to isolate the cold air."
In Baosteel's hot rolling workshop, red steel billets are passing through the heating furnace at 1250℃. On the pipe gallery, only 3 meters away from the flames, the valve body of a gate valve was burned dark red. "This is the ability of Inconel 718 material," said Zhang Gong, the equipment director, wiping his sweat. "Look at the thermal imager, the valve cavity temperature is 732℃, but the flange surface is always controlled below 180℃."
In the hydrocracking unit area of Zhenhai Refining and Chemical, engineer Chen Li is calibrating the bolts of the DN80 valve with a torque wrench. "The thickness of this valve body is 1.8 times that of an ordinary gate valve," he tapped the luminous surface, "A182 F22 material is normalized three times during forging, and the grain size can reach ASTM grade 7."
In the Yanshan Petrochemical Maintenance Workshop, operator Master Wang is turning the 450mm diameter cast iron handwheel. As the valve stem rises steadily, the DN200 gate valve completes the 1832nd opening and closing operation. "This valve, which was put into production in 1998, has a handwheel thread that still maintains a 0.1mm matching clearance." He said, tapping the spokes that are shining with patina.
Today, as the wave of digitalization sweeps across the industrial field, in a petrochemical plant maintenance workshop, a Gear Operated Gate Valve that has been in service for 18 years is being slowly turned by a worker. With the uniform "click" sound from the bronze gearbox, the gate with a diameter of 300mm is precisely in place - this seemingly traditional mechanical device still plays an irreplaceable role in modern industry.
