Needle valve is a kind of can accurate regulating valve in a wide range of USES, such as flame cutting cutting distance, is used to regulate the knob to the flame temperature of the needle valve, needle valve and instrument is an important part of the instrument piping system. Cut-off valve and ball valve is used to open or cut off the line.
The purpose of any valve are cutting fluid. Depending on the valve core, can be divided into the cut-off valve, gate valve, plug valve, ball valve, the disc valve, needle valve, etc. Needle valve of the valve core is a very sharp cone, it is 14 needle valve like a needle is inserted into the seat of the name.
Needle valve shape can withstand more pressure than other types of valve, and has good sealing performance, so usually for small flow, high pressure gas or liquid medium sealing. The shape of needle valve is suitable for use with pressure gauge.
According to the specific requirements of the application of high pressure ball valve, the user should choose to meet the requirements of these ball valve, as in a ball valve excellent qualities and very good applicability, fully meet the application requirements, guarantee a good job in all aspects of application: material quality: to be made of fine material has excellent material of high pressure ball valve, quality is very good, can meet the quality level will be higher. So everyone should choose the material excellent ball valve, in 38 needle valve order to ball valves excellent quality remained stable in the application of structure, reliable function. Structure suitable: application of high pressure ball valve structure shape and size will have specific requirements, need to assure you choose suitable ball valve structure, to be able the normal is installed in the pipeline system and meets the requirements of installation effect, after the ball valve to function normally.
Instrument is an important part of the pipeline system. It mainly includes the cut-off valve and ball valve. Its function is to open or cut off the pipeline route. Needle valve installation, convenient disassembly, rapid connection, fireproof and explosion-proof, high resistance to high pressure, as well as good sealing performance. Needle valve sealing performance is good, long service ball valve manufacturer life. Even if the sealing surface is damaged, only need to replace parts can also continue to use. Installing a needle valve type, medium flow direction should be consistent with the direction arrow on the valve body. Manual cut-off valve and ball valve can be installed in any position.
