AISI 904L Needle Valves
AISI 904L Needle Valves are regulating valves that allow fine control of clean gases and fluid flowing through the pipeline. Needle valves are small sized valves and generally capable of relatively low flow rates. 904L SS needle valves can be used to start, stop, and regulate the flow rate within a pipeline.
Anand Steels is a manufacturer and supplier of AISI 904L needle valves with size ranging from 1/8” to 2” NPS. AISI 904L valves are generally manufactured with screwed ends but flanged, socket-weld and butt-weld can also be made available on make-to-order basis. 904L needle valves and valves parts are constructed with ASTM A182/A182M F904L, A276/A276M type 904L and A479/A479M UNS N08904 material specifications. Stainless steel 904l needle valves are duly marked for traceability. We offer worldwide shipping by Sea or Air freight options.
