Fine chemical processing valves control corrosive, toxic and
\nhigh-purity media in reactors, dosing systems, transfer lines and
\nutility systems. WDL Valve supplies ball, butterfly, diaphragm,
\nglobe, needle and control valves with metallic or lined construction
\nselected for the actual chemical process.<\/p>\n<\/header>\n

\n

Where Are Fine Chemical Valves Used?<\/h2>\n

Fine chemical processing valves are used for raw-material feeding,
\nreactor isolation, chemical dosing, sampling, product transfer,
\ncleaning and utility control. Typical media include acids, alkalis,
\nsolvents, catalysts, additives and high-purity liquids.<\/p>\n

Each valve must match the chemical composition, concentration,
\ntemperature and pressure. Leakage limits, cleaning procedures,
\nsuspended particles and operating frequency also affect the final
\nvalve design.<\/p>\n<\/section>\n

Materials for Corrosive Chemical Service<\/h2>\n

Common valve materials include stainless steel, duplex stainless
\nsteel, titanium, zirconium, nickel, Monel, Hastelloy and other
\ncorrosion-resistant alloys. PTFE, PFA or other lined construction
\nmay be considered when metallic materials are unsuitable for the
\nprocess medium.<\/p>\n

Material selection must consider the complete chemical composition.
\nA material that resists a pure acid may behave differently when the
\nprocess also contains water, chlorides, oxidizers or other chemicals.
\nConcentration and temperature must therefore be provided together.<\/p>\n<\/section>\n
