Регуляторы для высокого давления

  • Совместимость с катализируемыми и водорастворимыми материалами 
  • Ручное или пневмоприводное управление 
  • Вольфрамовые и карбидные материалы для коррозионной устойчивости 
  • Картридж клапана обеспечивает быструю очистку и замену 
  • Компактность и малый вес – идеально для распылительных аппаратов
