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 valve configurations. HLN Series needle valves are designed for pressures up to 10,000 psig (689 bar)
