NV1 Series Needle Valves
NV1 Series Needle Valves
Features
Maximum operating pressure: 5000 psi ( 345 bar ) ( For pressure limitations under high temperature conditions, refer to pressure-temperature table )
V type stem is standard; R, K, and N type stem are also available
End connections: GENLOK and NPT ( please refer to the specification tables for available dimensions )
Straight pattern is standard, angle pattern is optional
Panel mounting available
Cleaned and degreased for oxygen service according to CGA G-4.1 and ASTM G93 Class C, respectively
Every valve is factory tested for leakage at 1000 psi ( 69 bar ) Adjust packing nut when working pressure is higher than 1000 psi to prevent leakage.
