What brand of ball valve is better?

Like Jiebao fluid, it is durable, and ***, it is also a sanitary product.

Ball valves will have many specifications and models according to the specific application requirements, so the ** is not the same. According to statistics and usage.

1. Mingbao valve.

Shanghai Mingbao Valve **** is committed to the development of new valve products, and has achieved good results in ball valves, globe valves and gate valves. Now the company has developed into a modern science and technology enterprise integrating valve research and development, production and sales. The company has strong technical force, and has the ability to design and manufacture various types of valves with various professional and technical personnel and senior engineers.

Our factory mainly produces nominal diameter DN6-DN800) according to international ISO, American APIANSI, Japanese JIS JPJ, and Chinese GBJB standards, nominal pressure level 150L-1500LB (working temperature-40-680). Production of valve varieties: ball valves, butterfly valves, gate valves, globe valves, check valves, various engineering construction water conservancy control valves and other series of valves.

The main materials of the valve are stainless steel, carbon steel, alloy steel, ultra-low carbon stainless steel and titanium, etc., and can be smelted and manufactured according to the special requirements of customers.

2. High-pressure valves.

Lanzhou High Pressure Valve Factory (formerly Lanzhou High Pressure Valve Factory) is a key backbone enterprise in the production of high and medium pressure valves under the former Ministry of Machinery Industry, and the vice chairman unit of China General Machinery Valve Industry Association. Lanzhou high-pressure valve has always been a high starting point, high investment strategic vision to build the core competitiveness of technological innovation as the main body, 16 new products have obtained national patents. The valve R&D center established by the company in cooperation with Lanzhou University of Technology has been recognized as a provincial enterprise technology center by the Ministry of Science and Technology, and many of its products have filled the technical gap of major domestic equipment manufacturing industry.

Summary. Hello dear, the gate valve is better, the advantages of the gate valve: 1. The flow resistance is small, the medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small.

2. It is more labor-saving when opening and closing, which is compared with the globe valve, because whether it is open or closed, the direction of movement of the ram is perpendicular to the direction of medium flow. 3. The height is large, the opening and closing time is long, the opening and closing stroke of the ram is large, and the lifting is carried out through the screw. 4. The phenomenon of water hammer is not easy to occur, because of the long closing time.

5. The medium can flow in any direction on both sides, which is easy to install, and the two sides of the gate valve channel are symmetrical.

Hello dear, the gate valve is better, the advantages of the gate valve: 1. The flow resistance is small, the medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small. 2. It is more labor-saving when opening and closing, which is compared with the suffocation ratio of the globe valve, because whether it is open or closed, the direction of the ram movement is perpendicular to the direction of the medium flow.

3. The height is large, the opening and closing time is long, the opening and closing stroke of the ram is large, and the lifting is carried out through the screw. 4. The water hammer phenomenon is not easy to produce a bright mask, because of the long closing time. 5. The medium can flow in any direction on both sides, which is easy to install, and the two sides of the gate valve channel are symmetrical.

Gate valve and ball valve are two different valves, the use is also different, the advantages of ball valve: 1, with the lowest flow resistance (actually 0); 2. Because it will not get stuck when working (when there is no lubricant), it can be reliably used in corrosive media and low boiling point liquids; 3. In a large range of pressure and temperature, it can achieve complete sealing; 4. It can realize rapid opening and closing, and the opening and closing time of some structures is only to ensure that the rubber can be used in the automation system of the test bench. When the valve is opened and closed quickly, there is no impact in operation; 5. The spherical closing part can be automatically positioned at the boundary position; 6. The working medium is sealed on both sides; 7. When fully open and fully closed, the sealing surface next to the ball and the valve seat is isolated from the medium, so the medium passing through the valve at high speed will not cause the erosion of the sealing surface;
