Needle valve for ammonia
Alias: liquid ammonia needle valve ammonia needle valve
Model: AJ13W-160P AJ23W-160P AJ63W-160P
Introduction to needle valve for ammonia:
Needle valves for ammonia, stainless steel needle valves, threaded needle valves, and welding needle valves are forged from high-quality carbon steel and stainless steel (1Cr18Ni9Ti) or heat-resistant alloy steel, and the sealing surface is welded by hard alloy surfacing, which are widely used in petroleum, petrochemical, natural gas, chemical industry, metallurgy, power, light industry, environmental protection, scientific research, food, shipbuilding and other industries.
