Descote specializes in the manufacture of high integrity bellow seal globe and check valves for hazardous media and emission control in the chemical, petrochemical and nuclear industries.
Services such as chlorine, phosgene, anhydrous Hydrogen Chloride (AHCL), anhydrous Hydrogen Fluoride (AHF), other environmentally sensitive fluids and thermal oils are typical applications.
Products include manual, automated and control bellows sealed and packed valves in all materials, sizes and pressures.
Primary Seal -- multi-wall, hydroformed bellows ensures ZERO STEM LEAKAGE.
Globe Valves for positive shutoff -- proven performance and many advantges over plug and gate valves.
Hard knife effect seats -- to cut through iron fluoride and other process deposits.
Metal seated -- inherently fire-safe and fully pressure/ temperature rated.
Easy to operate -- no need for handwheel wrenches, making the valves safe and reliable.
Face to Face -- to match globe, gate and plug valves in ANSI Class 300 -- no piping modification needed when replacing gate or plug valves.
Manual and actuated isolation valves, instrumentation and modulating control valves, all from one manufacturer.
Hastelloy C valve trim at no extra cost. We can do this because every year we manufacture thousands of valves with Hastelloy C trim. These valves are used on AHF, choline, AHCI, phosgene ,etc.
Lowest maintenance-- HF alkylation valves from Descote work reliably without maintenance, resulting in longer life cycles than other valves.
Descote valves are listed in the Phillips HF Alkylation Process Design Specification manual.
Descote valves meet all of the UOP qualification requirements for severe HF service in UOP's HF Alkylation units.
