Advantages, disadvantages and technical parameters of stainless steel gate valve

Release Date: June 01, 2017


1. The fluid resistance is small, and the sealing surface is less brushed and eroded by the medium.

2. Less effort to open and close.

3. The flow direction of the medium is not restricted, does not disturb the flow and does not reduce the pressure.

4. Simple shape, short structure length, good manufacturing process and wide application range.


1. It is easy to cause erosion and abrasion between sealing surfaces, and it is difficult to maintain.

2. The size is large, it needs a certain space to open, and the opening and closing time is long.

3. The structure is more complicated.

Technical Parameters:

1. Nominal pressure: 1.0MPa, 1.6MPa, 2.5MPa
