1、Classification of Stainless Steel Gate Valves:

2、Advantages of Stainless Steel Gate Valve:

1. It has low fluid resistance, the sealing surface is little scoured and eroded by the medium;

2. Opening and closing is labor-saving;

3. The flow direction of media is unrestricted;

4. Good manufacturing technology, reliable sealing performance, corrosion resistance and wide application range.

3、Disadvantages of Stainless Steel Gate Valve:

1. It is easy to cause erosion and scratch between sealing surfaces；

2. The overall dimension is large, so it needs a certain space for opening, the opening and closing time is long；

3. Complex structure.

4、Precautions for Installation of Stainless Steel Gate Valve:

1. It is generally installed horizontally in the pipeline;

2. Hand wheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited;

3. The bypass valve should be opened before the gate valve with bypass valve is opened (To balance the pressure difference between the inlet and outlet and reduce the opening force);

4. The gate valve with transmission mechanism should be installed according to the provisions of the product operation manual;

5. If the valve is opened and closed frequently, lubricate it at least once a month.
