Needle Valves | LN Series Locked Bonnet Needle Valves

LN Series needle valves are designed for the special temperature, pressure and compatibility required in many severe service applications in the oil & gas, chemical/petrochemical, and power industries.  The locked bonnet and live-loaded chevron packing are ideal for applications having high vibration and dynamic pressures and temperatures.   LN Series valves are also available in gauge and block & bleed valves configurations.

NEW! HLN Series Needle Valves

HLN Series needle valves are designed for applications with working pressures up to 10,000 psig (689 bar) and temperatures from -100 to 1200°F (-73 to 648°C).  

  • Temperature: -100 to 1200° F (-73 to 648° F)
  • Pressure: up to 10000 psig (689 bar)
  • Valve Orifice Sizes (max. Cv):
    • HLN4:  0.156 orifice (0.34)
    • HLN6:  0.250 orifice (0.85)
  • Patterns: Straight
  • Body Materials: 316 SS
  • Packing Materials: PTFE (Standard), PEEK, and flexible graphite.  
  • Stem types: Non-rotating vee,  regulating and metering
  • End Connection Types: Duolok, Unilok and Griplok tube fittings, NPT and BSP pipe ends, and tube and pipe socket weld
  • End Connection Sizes
    • Fractional: 1/4 and 1/2 in.
