Valves for fertilizer plants
Fertilizer production combines chemicals, power and water. One plant needs valves for ammonia, acids, steam and large volumes of cooling water.

Ammonia and gases
Ammonia service uses steel valves with no copper alloys in contact with the medium and tighter seat and packing requirements. Refrigerated ammonia also needs steel with proven low-temperature toughness.
Acids and solutions
Nitric, sulphuric and phosphoric acids need stainless steels and special alloys selected for concentration and temperature. Salt solutions tend to crystallise, so designs without dead zones and with heat tracing are preferred.
Steam and water
On-site boiler houses and CHP plants, cooling towers and recirculating water use general-purpose gate, butterfly and check valves, where price and stock availability matter.
Where TAZ fits
TAZ covers general-purpose valves for water, steam and utilities and GOST steel gate and globe valves. Special designs for aggressive media are discussed case by case.
