What is the purpose of the check valve? If you need fluid to flow through a pipe in one direction, you can't do without them. Check valves are designed with a two-way system with openings that allow fluid to pass through. After the flow has passed, the valve closes to prevent backflow. Check valves can also close automatically if downstream pressure is excessive.
Common uses of check valves:
Water and waste pumping systems
Water pipe
Sewage treatment system
Heating system
Fire hose
Marine and naval industries
Oil and gas pipelines
Flush toilet device
There are many different types of check valves, including rotary check, lift check, piston check, and ball check.
Soft-sealing gate valve is the replacement of the traditional gate valve, the use of flexible disc produce trace deformation compensation effect, achieve good sealing effect, the valve has the switch light, reliable sealing, elastic memory and long service life etc, can be widely used in tap water, sewage, construction, food, electricity, medicine, metallurgy, textile, energy systems and other fluid on the pipeline as the adjusting and intercepting device is used.

Main parts and materials
This globe valve features a valve body made of cast iron GG25 and a stainless steel valve seat. Cast iron globe valves are commonly used in applications such as heating and water distribution. This type of cast iron globe valve is suitable for both commercial and industrial use, with typical services including cold and hot water, HVAC, and other general utility services.
Product Features:
DIN standard shutoff valves feature a double strong corrugated seal design (corrugated + packing) to ensure zero stem leakage. No fluid loss improves plant safety and complies with international sealing standards. The sealing surfaces of the shut-off valve are covered with cobalt-based hard alloys with good wear and corrosion resistance, good friction resistance and long life. Stem is tempered and surface nitrided for good corrosion and friction resistance; stem lift position indication for better visualization.

A gate valve is a type of valve that uses a gate or wedge-shaped disc to stop or start the flow of a fluid. The gate is attached to a stem that is operated by a handle or a wheel, and it can be raised or lowered to open or close the valve. When the gate is fully raised, it allows the fluid to flow freely through the valve. When the gate is fully lowered, it blocks the flow of the fluid.
Gate valves are widely used in a variety of applications, including oil and gas, chemical processing, water treatment, and power generation. They are available in a range of sizes and materials to suit different applications and fluid types.
In China, gate valves are commonly used in industrial piping systems and are designed to meet Chinese national and industry standards. They are known for their reliability, durability, and ease of use, and they are often used in applications where a tight seal is required to prevent leaks. Like JIS flanged ball valves, gate valves are typically connected to the rest of the piping system using flanges, which are fastened together with bolts or other fasteners.
The valve body of the gate valve can be made of metal. Such as: forged steel gate valve, stainless steel gate valve, alloy gate valve, bronze gate valve, cast steel gate valve, carbon steel gate valve, etc. Among them, forged steel gate valves are widely used, especially as a cut-off device when the size is greater than 50mm. The main body can also be made of non-metallic materials. For example, ceramic gate valves have good wear resistance and hardness. Some other gate valves are made of special materials, such as Hastelloy gate valves, special steel gate valves and special alloy gate valves. To transport and process strong corrosive media, duplex stainless steel gate valves or super stainless steel gate valves are usually used to alleviate the problem, because they can work well in areas with corrosive environments.

Check valves are usually installed in the pipeline to prevent backflow. A check valve is basically a one-way valve in which the flow can flow freely in one direction, but if the flow turns, the valve will be closed to protect the piping, other valves, pumps, etc. If the flow is diverted without a check valve installed, a water hammer may occur. Water hammer often occurs with extreme force and can easily damage pipes or components.
Check Valve Definition
A check valve is a fundamental component in fluid systems, playing a crucial role in regulating the flow of liquids or gases. This simple yet essential device prevents backflow and maintains the desired direction of fluid movement. Understanding the function and types of check valves is essential for engineers, manufacturers, and anyone involved in fluid control systems.
How Does a Check Valve Work?
Check valves operate on a straightforward principle: allowing fluid to flow in one direction while preventing reverse flow. The valve consists of a movable mechanism, often a disk or a flap, and a body with an inlet and an outlet. When the fluid flows in the intended direction, the mechanism opens, enabling the fluid to pass through. However, when there is a reversal in flow, the mechanism closes, preventing the fluid from going backward.
