The body is made of high-grade ductile iron, which is about 20% to 30% lighter than traditional gate valves and is easy to install and maintain.

Generally, gate valves have two sealing surfaces, and the processing and manufacturing are more complicated than globe valves.

The internal medium channel of the valve body is straight, the medium flows in a straight line, and the flow resistance is small.

There are many domestic manufacturers of gate valves, and most of the connection sizes are not uniform.

When the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate plate is pressed to the valve seat on the other side by the me...

The opening and closing part of the gate valve is the gate plate. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened an...

The gate valve is a gate that opens and closes. The movement direction of the gate is perpendicular to the direction of the fluid.

The valves have been tested for strength and sealing before leaving the factory, and all connections should remain in their initial state during use.

Flat gate valves are suitable for natural gas, petroleum, chemical industry, environmental protection, urban pipelines, gas pipelines and other transportation pipelines, venting systems and steam s...

For oil and natural gas transmission pipelines, single or double gate flat gate valves should be used.

When the medium pressure is low, the sealing force of the metal sealing surface is not enough to achieve a satisfactory seal.

The flow resistance is small, and the flow resistance of the non-necked pipe is similar to that of the short pipe.
