The driving mode of swing check valve is automatic, the connection mode can be selected from flange, clip type, welding, thread, structure can be selected with swing type, sealing structure can be selected with PTFE, PPL, hard seal, pressure range PN10~ PN160, the nominal diameter is DN15-1200mm, the material can be selected from WCB, 304, 316, alloy steel and so on.

The comprehensive feature of the plug valve is that it has a long service life and high reliability. It is a good choice for many corrosive, abrasive, highly toxic, continuous operation media and devices, and has application advantages and extensive applications in the chemical industry.

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.

A gate valve, also known as a sluice valve, is a valve which opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow.

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.
