News & Notes
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.
It mainly relies on the flow of the medium itself in the pipeline to generate power, thereby automatically opening and closing the valve. Specifically:
In pump stations, when the water pump stops working or suddenly loses power, the fluid in the pipeline may continue to flow due to inertia, resulting in reverse pressure. Pressure Seal Check Valve can quickly close to prevent the fluid from flowing back, thereby protecting the water pump and other equipment from damage.
Natural gas is a flammable and explosive medium. Residual oil and oxygen contact may cause violent oxidation reaction, resulting in seal failure or safety accidents12.
The working principle of High Temperature Check Valve is based on a simple and ingenious design: it relies on the flow of the medium itself to automatically open and close the valve disc, thereby realizing the function of preventing the medium from flowing back. When the medium flows in the normal direction, the pressure generated by it pushes the valve disc, so that it overcomes its own gravity and spring force (if there is a spring assist), thereby opening the valve and allowing the medium to pass smoothly. At this time, the valve disc is like being gently lifted by an invisible force, making way for the flow of the medium.
In the steel-like industrial pipeline network, the forged steel swing check valve is like a guardian in armor, using precision mechanical structure and high-strength materials to build a barrier against backflow, interpreting the philosophy of safety between movement and stillness.
Big Size Check Valve (nominal diameter ≥ DN300) uses a one-way flow design and relies on the kinetic energy of the medium to automatically open and close the valve disc, effectively preventing fluid backflow, avoiding pump reversal, pipeline water hammer and equipment damage16. Its lack of external power dependence simplifies the system control logic and reduces the complexity of operation and maintenance35.
As a key protective device for industrial fluid systems, alloy check valves have material properties and performance advantages including corrosion resistance, high temperature stability, mechanical strength and sealing.
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.
