As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

You can search, each valve factory has different fist products.

The type of valve should be selected according to the specific application scenario and the function to be implemented. Here are some general recommendations:

1.Butterfly valve: suitable for small and medium-sized pipes, easy to operate, fast opening and closing, low fluid resistance, usually used for flow regulation, cutting off and regulating the flow of media.

However, butterfly valves can be leaked and worn at high temperatures and pressures, so caution should be exercised in such cases.

2.Gate valve: suitable for large-diameter pipelines and high-temperature and high-pressure media, with simple structure and good sealing performance, suitable for high-viscosity media and media containing particulate impurities. However, because the opening and closing of the gate valve requires a large operating force and the opening and closing time is long, it is not suitable for frequent operation.

Haidun knife gate valve.

3.Ball valve: suitable for general small and medium-sized pipes, fast opening and closing, good sealing performance, usually used to cut off and cut off the flow of medium. However, the fluid resistance of the ball valve is large, so it is not suitable for situations where convection resistance is required.

Haidun V-type ball valve.

4.Globe valve: suitable for occasions with strict requirements for medium flow, which can accurately control the flow rate.

The shut-off valve has a small opening and closing force and a short opening and closing time, so it is suitable for occasions that require frequent operation. However, the fluid resistance of the globe valve is also relatively large, so it is not suitable for occasions where convection resistance is required.

It is necessary to select the appropriate valve type according to the actual situation, and combine other factors, such as materials, working environment and other factors to make a comprehensive consideration.

Compared with ordinary gate valves, knife gate valves have simple structure, small size, flexible operation, easy installation, and are suitable for media with high consistency and solid particles. The full-bore knife gate valve design allows the valve to be used in dirty media, and the replaceable seat and packing make valve maintenance easy. Although the performance is better, because the knife gate valve** is about 20% higher than the ordinary gate valve, it has not replaced the ordinary gate valve.

Electro-hydraulic gate valve is a kind of gate valve, there are single gate and double gate plate, single gate wedge gate valve, simple structure, reliable use, but the accuracy of the sealing surface angle is required to be higher, processing and maintenance are more difficult, the possibility of wedge is very high when the temperature changes, the double gate wedge gate valve is easy to bond in water and vapor medium, affecting the seal, more mainly the upper and lower baffle is easy to produce rust after long-term use, the gate is easy to fall off, the electro-hydraulic gate valve is electro-hydraulic to start, greatly reducing the difficulty of opening, It is widely used in mining power plants, sewage treatment, industrial pipelines, food, health, medicine and other professional pipeline systems. With its small size, small flow resistance, light weight, easy installation, easy to disassemble and other advantages, the electro-hydraulic gate valve completely solves the difficult problems of large flow resistance, large weight, difficult installation and large floor area of ordinary gate valves.

Recommend the light valve, it's not bad! Knife gate valve from the eighties into China, in less than 20 years, its scope of use from the ordinary field to a broader range of industries, from the mine power plant coal preparation, gangue, slag discharge, to the development of urban sewage treatment, from the general industrial pipeline to food, health, medicine and other professional pipeline systems.

Knife gate valve is also known as knife gate valve, knife gate gate valve, slurry valve, mud valve, its opening and closing parts are ram, the direction of movement of the ram is perpendicular to the direction of fluid, relying on the blade-shaped ram that can cut fiber materials to cut off the medium, the ram has two sealing surfaces, the most commonly used mode gate valve two sealing surfaces form a wedge, wedge-shaped angle varies with the valve parameters, usually 50, the wedge knife gate valve gate plate can be made into a whole, called a rigid ram; It can also be made into a ram that can produce a slight amount of deformation to improve its manufacturability and make up for the deviation of the sealing surface angle in the processing process, which is called an elastic ram. There is virtually no chamber in the valve body, the ram is raised and lowered in the side guide groove and pressed on the valve seat by the lugs at the bottom, and the O-shaped seal seat can be used to achieve bidirectional sealing when high medium tightness is required. The knife gate valve has a small installation space, low working pressure, is not easy to accumulate debris, and is low.

When the knife gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, the sealing surface of the ram is pressed to the valve seat on the other side by relying on the medium pressure to ensure the sealing of the sealing surface, which is self-sealing. Most of the knife gate valves are forced sealed, that is, when the valve is closed, the ram should be forced to the valve seat by external force to ensure the tightness of the sealing surface. This type of valve should generally be installed vertically in the pipeline.

Hope it helps!

The opening and closing parts of the knife gate valve are the gate, and the direction of movement of the gate is perpendicular to the direction of the fluid, and the manual knife gate valve can only be fully opened and closed, and cannot be adjusted and throttled.

The knife gate valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, light and flexible operation, small size, smooth channel, small flow resistance, light weight, easy installation, easy disassembly, etc., and can work normally under the condition of working pressure and operating temperature -29-650. The knife gate valve has a shear function on the gate, which can scrape off the adhesive on the sealing surface and automatically remove debris, and the stainless steel gate can prevent seal leakage caused by corrosion.
