Product Advantages:
Ball valve is a new valve widely used in recent years, it has the following advantages:
1.The fluid resistance is small, and its resistance coefficient is equal to the same length of pipe section.
2.Simple structure, small size and light weight.
3.Tight and reliable, the sealing surface material of ball valve is widely used in plastic, good sealing, and has been widely used in vacuum system.
4.Easy to operate, fast to open and close, from full open to full close as long as the rotation of 90 , easy to remote control.
5.Easy maintenance, ball valve structure is simple, sealing ring is generally active, disassembly and replacement are more convenient.
6.When fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium, which will not cause erosion of the sealing surface of the valve when the medium passes through.
7.Wide range of applications, from small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.Valves of this type shall generally be installed horizontally in pipelines.
Three-piece ball valve with internal thread connection belongs to a type of ball valve with internal thread connection.Valve body casting adopts advanced technology introduced from Taiwan, with reasonable structure and beautiful shape.
Feature:
Three-piece ball valve with internal thread connection belongs to a type of ball valve with internal thread connection.Valve body casting adopts advanced technology introduced from Taiwan, with reasonable structure and beautiful shape.The valve seat USES the elastic sealing structure, the sealing is reliable, opens and closes easily.The valve stem adopts the downassembly structure with inverted seal, and the valve stem will not be flushed out when the valve chamber increases pressure abnormally.
Three-piece ball valve connection form also butt welding (BW) socket welding (SW), and can be equipped with international standard ISO bracket platform and locking device.Can set 90 switch positioning mechanism, according to the need to add a lock to prevent misoperation, ball valve is a rotation of 90diameter ball valve) flow coefficient flow resistance coefficient is small, simple structure, long service life, easy to maintain.
Application:
widely used in the system control of chemical industry, petroleum industry, light textile industry, electric power industry, food and pharmaceutical industry, refrigeration industry and paper industry.Driving mode: manual, electric and pneumatic.
Application: It is suitable for regulating flow and intercepting medium on the gas pipeline of water supply and drainage, such as pharmaceutical, chemical, petroleum, electric power, light textile, paper making, etc
Product feature:
1, simple and compact structure, small and light, easy to disassemble and maintenance, and can be installed in any location
2, 90 degrees of rotation, open and close quickly
3, flow characteristics tend to be straight, good regulation performance4, choose different parts material, can be applied to a variety of media
Application:
It has the function of automatic compensation pipeline expansion and cold contraction for easy loading and unloading. It is used as the best device for regulating flow rate and carrying cut-off body on petroleum, chemical, electric power, paper making, water supply and drainage and municipal construction pipelines with the temperature below 425 and nominal pressure below 1.6MPa.
Product feature:
1. Unique structure, flexible design, light weight, labor saving, quick opening and closing
