Products Description
Advantages of gate valves
The fluid resistance is small, the sealing surface is scoured and eroded by the medium is small.
Open and close less effort.
The flow direction of the medium is not restricted, not disturbing the flow, not reducing the pressure.
Simple shape, short structure length, good manufacturing technology, wide range of application.
Disadvantages of gate valves are as follows:
It is easy to cause erosion and abrasion between sealing surfaces, and it is difficult to maintain.
The external size is large, the opening needs a certain space, the opening and closing time is long.
The structure is more complex.

Advantages of check valves
1, stainless steel globe valve simple structure, manufacturing and maintenance is more convenient.
2. Stainless steel globe valve has small working stroke and short opening and closing time.
3. Stainless steel globe valve has good tightness, small friction force between sealing surfaces and long service life.

The advantages of ball valves
1， The lowest flow resistance ,
2，because it will not get stuck when working (in the absence of lubricant), it can be reliably used in corrosive media and low
boiling point liquids;,
3， in a large range of pressure and temperature, can achieve complete sealing;,
4， can realize fast opening and closing, the opening and closing time of some structures is only 0.05~0.1s, in order to ensure

The advantages of pneumatic butterfly valve
1, compact and light, easy to disassemble and repair, and can be installed in any position.version
2, Simple structure, compact weight, small operating torque, 90° rotation to open quickly.
3, flow characteristics tend to straight line, good regulation performance.
4. he connection between the pneumatic butterfly plate and the valve stem adopts no pin structure to overcome the possible
internal leakag
