Product Detail

Gate valve

Product overview

It is a gate valve of an opening and closing part. The movement direction of the gate valve is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by contact between the valve seat and the gate valve. Usually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1Cr13, STL, stainless steel, etc. The gate valve has a rigid gate valve and an elastic gate valve. According to the difference of the gate valve, the gate valve is divided into a rigid gate valve and an elastic gate valve.

Product features

1. Small flow resistance. The medium channel inside the valve body is straight-through, the medium flows in a straight line, and the flow resistance is small.

2. It is more labor-saving when opening and closing. Compared with the stop valve, the movement direction of the gate valve is perpendicular to the flow direction of the medium whether it is open or closed.

3. The height is large, the opening and closing time is long, the opening and closing stroke of the gate valve is large, and the lifting is carried out by a screw.

4. Water hammer phenomenon is not easy to occur.

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

6. Simple shape, short structure length, good manufacturing processability, and wide application range.

7. Smooth channel, small flow resistance, stainless steel and hard alloy sealing surface, long service life, reliable sealing, easy and flexible operation.

Widely used: in pipelines of various systems in petroleum, chemical, hydropower, and thermal power plants. Applicable to: water, oil, steam, acid, alkali, ammonia, urea, sulfur-containing natural gas, etc.
