Valve, is there any difference between the two types of valves?

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. 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.

Which two? There is so little information available.

Gate Valve Gate Valve.

A gate opening and closing part ram, the direction of movement of the ram is perpendicular to the direction of the fluid, and the gate valve can only be fully opened and closed, and can not be adjusted and throttled. The gate valve is sealed through the contact between the valve seat and the ram, and usually the sealing surface will be surfacing with metal materials to increase the wear resistance, such as surfacing 1Cr13, STL6, stainless steel, etc. The gate has a rigid gate and an elastic gate, and according to the different gates, the gate valves are divided into rigid gate valves and elastic gate valves.

When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, only rely on the medium pressure to press the sealing surface of the ram roller to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forced to seal the code, that is, when the valve is closed, it is necessary to rely on external force to forcibly press the gate to the valve seat to ensure the tightness of the sealing surface.

Movement mode: The gate plate of the gate valve moves in a straight line with the valve stem, which is also called the open rod gate valve. Usually there is a trapezoidal thread on the lifting rod, which changes the rotary motion into linear motion through the nut at the top of the valve and the guide groove on the valve body, that is, the operating torque into operating thrust.

When the valve is opened, when the ram lift height is equal to 1:1 times the valve diameter, the flow of the fluid is completely unobstructed, but this position cannot be monitored during operation. In actual use, it is marked by the apex of the valve stem, that is, the position that cannot be opened, as its fully open position.

In order to account for the lock-up phenomenon of temperature changes, it is usually rewound back to the apex position and then reverses 1 2 1 turns as the position of the fully open valve. Therefore, the fully open position of the valve is determined by the position of the ram (i.e., the stroke). Some gate valve stem nuts are located on the gate plate, and the handwheel rotates to drive the valve stem to rotate, and the gate plate is lifted, and this valve is called the rotary rod gate valve or the dark rod gate valve.
