JS-91 needle valve Overview
JS-91 needle valve instrumentation measurement system is an important part of pipe systems, there are globe valves and ball valves, its function is to open or cut off the pipeline access. Needle valves have the advantages of easy installation and removal, connection and fastening, is conducive to fire prevention, explosion and pressure resistance, good sealing performance, etc., is a advanced connection valve in power plant, oil refining, chemical plant and instrumentation measurement pipeline . Needle valve sealing is good, long life, even after the sealing surface is damaged, only need to replace the vulnerable parts, you can continue to use. The needle valve should be installed so that the flow direction of the medium matches the direction of the arrow on the valve body. Manual shut-off valve, ball valve can be installed in any position on the pipeline. Needle valve is a valve that can be precisely adjusted for a wide range of uses, such as flame cutting with a pitch, the knob to adjust the flame temperature is a needle valve, gauge needle valve instrumentation piping system is an important part of the system, there are Globe valve and ball valve, its function is to open or cut off the pipeline access. Depending on the spool, it can be divided into globe valve, gate valve, plug valve, ball valve, disc valve, needle valve, etc. • The spool of the needle valve is A very sharp cone, like a needle inserted into the seat, hence the name, JS-91 needle valve than other types of valves to withstand greater pressure, good sealing performance, it is generally used for smaller Flow, high-pressure gas or liquid medium seal needle type valve and pressure gauge with the most appropriate use of the general needle valve made of thread connections.
