SS316 Stainless Steel Corrosion Resistant Male Thread Straight Needle Valves
Needle globe valves and needle ball valves, which are used to open or close pipeline access, are two types of Ss316 stainless steel corrosion-resistant male thread straight needle valves that are a crucial component of the instrument measurement pipeline system. The needle valve gets its name from the fact that its spool, an extremely pointed cone, is put into the valve seat in the shape of a needle. Although their nominal diameters are small, needle valves can be employed in high-pressure, high-temperature pipeline conditions.
Ss316 Stainless Steel Corrosion Resistant Male Thread Straight Needle Valves
Ss316 Stainless Steel Corrosion Resistant Male Thread Straight Needle Valves are an important part of the instrument measurement pipeline system, mainly including needle globe valves and needle ball valves, which are used to open or cut off pipeline access. The spool of the needle valve is a very pointed cone, which is inserted into the valve seat like a needle, hence the name. Needle valves can be used in high-pressure, high-temperature pipeline media, but their nominal diameters are small.
Needle globe valves are used for precise flow control. The disc is usually integral with the valve stem, which has a very precise needle-shaped head that fits into the valve seat. Moreover, the thread pitch of the stem thread of the needle globe valve is thinner than that of the ordinary globe valve. Under normal circumstances, the size of the seat hole of the needle globe valve is smaller than the pipe size.
The features of Ss316 Stainless Steel Corrosion Resistant Male Thread Straight Needle Valves
①Compact and lightweight;
② PTFE sealing pressure device, absolutely no leakage when the valve stem is operated;
③The sealing packing under the thread can prevent the thread from being corroded by the fluid medium;
④Two flow ports with proper flow direction.
The instructions for use of Ss316 Stainless Steel Corrosion Resistant Male Thread Straight Needle Valves
①Before installing the needle valve, the remaining impurities in the pipeline must be flushed and removed;
② Install a filter at the inlet of the pipeline as much as possible to prevent impurities from blocking the valve core;
③When the needle valve is installed, the flow direction of the medium should be consistent with the direction of the arrow on the valve body.
