FNV-4MFA-B-K-X - Forged Brass Needle Valve Angle, 1/4" MNPT X 1/4" FNPT, Soft Stem Tip, O2 Cleaned

Forged Needle Valve – Series FNV 1/8” - 3/8” NPT 1/8” & 1/4” Dual Ferrule Tube Vacuum – 5000 PSIG (345 Bar) Description of Forged Needle Valves Series FNV Needle Valves feature a forged body, integral bonnet design with PTFE and metallic wafer stem packing. This provides leak-tight service from vacuum to the maximum operating pressure. Series FNV are available in Straight and Angle configurations, with NPT and Dual Ferrule Tube connections. The industry standard panel mounting allows the FNV to be a cost effective solution to many applications. Standard metal to metal stem and optional Soft Tip stem provide accurate metering over a wide range of pressures. The Series FNV can be ordered cleaned for Oxygen Service. Features • Metallic and PTFE Wafer Stem Packing provides low operating torque • Panel Mounting Standard • Metal to Metal Standard, Optional Soft Stem Tip (PCTFE) • Straight or Angle Body Configurations • Male and Female NPT or Dual Ferrule Tube Connections • 100% Factory Tested Technical Data for Forged Needle Valves Maximum Operating Pressure @ 100º F Brass: 3000 PSIG (207 Bar) Stainless: 5000 PSIG (345 Bar) Temperature / Pressure Ratings Temperature, °F (°C): - 65 (-53) to 100 (37) Max.
