Product Description:

Metal-to-Metal Seal Ball Valves

Metal-to-Metal Seal Ball Valves are usually used in the industrial controlling pipeline services of high pressure, high temperature, severe corrosion and solid material containing industry, such as coal chemical, polysilicon and vitriol/ nitric acid. The leakage rate of metal-to-metal seal control ball valves can reach rate V. Top flange is designed per ISO5211 for easy amount various type of actuator.

Q:The difference between gate valve, ball valve and butterfly valve
Gate valve: there is a flat plate in the valve body which is perpendicular to the direction of the medium flow, and the plate is lifted and closed.Features: good tightness, fluid resistance small, open and close force is small, widely used, also have to regulate the flow performance, generally applicable to the large diameter of the road.Ball valve: the use of a hole in the middle opening of the ball as the spool, by rotating the ball to control the opening and closing of the hair.Features: the structure is simpler than the gate valve, small size, low fluid resistance, and can replace the role of gate valve.Butterfly valve: closure is a disk-shaped, around a fixed axis rotation of the valve body.The utility model has the advantages of simple structure, small size and light weight, and is suitable for making larger diameter valves. As the sealing structure and materials are still problems, it is only used for low pressure, for the transport of water, air, gas and other media!Own code words, hope to adopt!
Q:What's the difference between a hot melt ball valve and a ball valve in general? What's the use of it?
In general, both sides of the ball are wire interface, and hot melt ball valve on either side or side of the live connection with PP-R short tube, as a hot melt interface, so called hot melt ball valve. As for the use, there is no obvious difference, but the connection is different.
Q:Advantages of track ball valves
1., the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section. 2., simple structure, small size, light weight. 3., close and reliable, at present the ball valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used. 4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control. 5., maintenance is convenient, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient. 6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface. 7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.
Q:Pneumatic two stage ball valve principle
Two section type pneumatic ball valve, pneumatic piston two stage shut-off valve to achieve a two step or two step off the action of the cut-off valve is a special pneumatic valve, provides 0 degrees, 45 degrees, 90 degrees or 0 degrees, 90 degrees, three operating mode 180 degrees.
Q:Switch valve type, switch valve, ball valve or butterfly valve is good
Ball valve and butterfly valveBall valve is used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media.Butterfly valve, also known as shutter valve, can be used to control the air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. On the pipeline, mainly from cutting and throttling.
Q:Why can't the ball valve be screwed?
You are too weak, or else you are not in the right direction.
Q:Ball valve use?
The utility model has the action of rotating 90 degrees, and the cock body is a sphere, and has a round through hole or a passage through its axis.
Q:What's the difference between T ball valve and L ball valve?
This is the code for the three way ball valve and the three way plug valve flow passage. The L shape can only connect the two channels perpendicular to each other, and the T shape allows the three channels to communicate with each other or to connect two of them.
Q:How to distinguish between single and double ball valve?
I don't know what you mean by "single" and "double", but the ball valve can be divided into one, two and three.
Q:Principle of forced sealing ball valve
With spring to achieve forced sealing, not applicable to high pressure
