The plug valve is a closing or plunger-shaped rotary valve that opens or closes by rotating the passage port on the valve plug 90° degrees or the same as the passage port on the valve body.Plug valve is difference from knife gate valve. The plug of the plug valve may be cylindrical or conical shape.

Plug valves are best suited for use as a globe and closing medium as well as for shunting, but can sometimes be used for throttling depending on the nature of the application and the erosion resistance of the sealing surface. It is also commonly used for media with suspended particles due to the wip

The structure of piston check valve is similar to globe valve,but these two kinds of have have some differences between globe valve and piston check valve,the operation of piston check valve is flow automatic,the globe valve have a handwheel to operating,this is most difference of valve’s type.

The needle valve is evolved from the globe valve, sometimes called the needle valve globe valve. The specific difference is that the disc of the needle valve is a sharp cone, which is inserted into the valve seat like a needle. The needle valve is a kind of valve that can be precisely adjusted. For

Compared with the gate valve, the globe valve has the advantages of simple structure, good sealing performance and convenient manufacturing and maintenance; The gate valve and the globe valve are full-open and fully-closed valves.

Knife gate valve is kind of gate valve,but there is still have difference between gate valve and knife gate valve.The gate valve is a gate of the opening and closing part. The direction of movement of the gate is perpendicular to the direction of the fluid.

What is the difference between a butterfly valve and a globe valve? To put it simply: the globe valve has better adjustment performance than the butterfly valve, and the butterfly valve has poor regulation performance.

Compared with the gate valve, the globe valve has the advantages of simple structure, good sealing performance and convenient manufacturing and maintenance; the disadvantage is that the liquid resistance is large, and the opening and closing forces are large.

After the valve is used for a long period of time, the sealing surfaces of the valve disc and the valve seat will wear out and the tightness will be reduced. Repair sealing surface is a large and important work. The main method of repair is grinding.
