Do you know the Butterfly valve

 Butterfly valve, also known as flap valve, is a simple structure of the control valve can be used for low-pressure pipeline media control switch butterfly valve means the closure (valve flap or disc) as a disc, rotating around the valve shaft to open and close A valve.The different from it, Globe valve is a kind of forced-sealed valve.
Valves can be used to control the flow of various types of fluids such as air, water, steam, corrosive media, slurries, oils, liquid metals and radioactive media. Mainly in the pipeline cut off and throttling effect. Butterfly valve opening and closing pieces is a disc-shaped disc, the valve body around its own axis of rotation, so as to achieve the purpose of opening and closing or regulation.

The features of Knife-shaped Stainless Steel Gate Valve

There are many types of regulating valve body,Commonly used are Gost Globe Valve,Butterfly Valve.
Knife-shaped stainless steel gate valve using knife gate, play a good role in shear effect, It's most suitable for the fluid that are slurry, powder, fiber and other difficult to control.
Stainless steel knife gate valve range of use:
1. Mining, iron and steel industry - for coal, slag slurry, etc .;
2. Purification device - for wastewater, mud, dirt and water with suspended solids;
3. Paper industry - for any concentration of pulp, water mixture;
4. Ash power station - for the ash slurry.

What's the ball valve

Some people are familiar with the valve products like Cast Iron Ball Valve,DIN Lift Check Valve.Do you know what's the ball valve. I will introduce for you.

Opening and closing pieces (ball) by the valve stem and around the ball valve for rotational movement of the valve. It can also be used for the regulation and control of the fluid. Among them, the V-shaped ball valve with hard seal has a strong shear force between the V-shaped ball core and the metal valve seat of the hardfacing alloy. It is especially suitable for containing the fine particles And other media. The multi-pass ball valve in the pipeline not only can be flexibly control the merging of media, diversion, and flow switching, but also can close any channel and the other two channels connected. This type of valve in the pipeline should be generally horizontal installation. Ball valve in accordance with the drive is divided into: pneumatic valve, electric valve, manual valve.

The definition of Globe Valve

 Globe valve, also known as the cut-off valve,which is different from gate valve.Cast Iron Ball Valve is also common to see. Globe valve is a forced-sealed valve, so the valve is closed, the pressure must put pressure on the valve flap to force the sealing surface does not leak. When the medium from below the valve into the valve, the operating force needed to overcome the resistance that is the valve stem and packing friction and the thrust generated by the media pressure, off the valve force than the valve open, so the valve stem The diameter should be larger, otherwise it will happen valve stem bend.
