1-General Standard Name
Straight-through stainless steel welded throttling valve (needle throttling valve), also named instrument needle throttling globe valve, micro regulating flow control valve.
2-Structural Features
Connection: Both ends male thread butt weld with welded nozzle, suitable for instrument seamless steel pipe welding with convenient installation and high tightness.
Operation: Plum blossom plastic hand wheel manual operation, rising stem and high-precision conical plug for micro flow precise regulation.
Material: 304/316 stainless steel, high pressure resistance and corrosion resistance, suitable for clean medium, oil, gas and steam.
Function: Dual functions of flow throttling regulation + pipeline on-off shut-off; precisely lapped plug for stable micro flow control.
