Manual needle valve for local regulation of small flows and isolation of auxiliary lines. Model 658004 features female/female NPT threading, AISI 316L / 1.4404 body, polished exterior, and handwheel. Available from 1/4” to 1 1/2”.
Suitable for clean liquids or gases compatible with 316L, FKM, and PTFE. Used in:
The needle geometry facilitates gradual opening changes. Not a substitute for control valves with actuators when continuous automated adjustment is required.
Model 658004 is selected when piping or equipment has NPT female/female connections. For installations with parallel BSPP/ISO 228 threading, the corresponding ISO version is required to avoid mechanical incompatibilities and thread leaks.
Upon request, anti-static arrangement ATEX II 2G Ex h IIC T4 Gb / II 2D Ex h IIIC T135°C Db is available, as well as M.O.C.A. CE 1935/2004 compliance for food contact applications.
When to choose a needle valve?
When manual micro-adjustment of flow is required, not simple on/off isolation.
What should be checked before procurement?
NPT size, PN, temperature, elastomer chemical compatibility, and media cleanliness.
