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.
