N-Line Valves are designed for the changing needs of the oil and gas industries. We take into account that the produced or injected medium will frequently contain free water, chlorides, CO2, H2S, and other corrosive compounds. N-Line Valves are available in a wide range of body materials, varying from carbon steel to nickel alloy based materials. Valve internals to match the design conditions are numerous and include proprietary wear materials such as Tungsten Carbide. To avoid problems related to elastomeric explosive decompression the standard seal material selection is non-elastomeric PTFE and PEEK. Bonnet seals are double tapered metal for the ultimate in sealing reliability
