ZHD Series (Electric or Pneumatic) Minimum Flow Control Valve
ZHD multistage cage fanaraha-maso valve nampiasa multilevel cage symmetric sleeve contol valve. Izy io dia mifehy ny hafainganam-pandeha antonony ao anatin'ny valva, ary mampihena be ny tabataba ataon'ny entona avo lenta na etona ao anaty valva, manara-penitra multistage ny tsindry mampihena ny fampihenana mahomby amin'ny fisorohana ny cavitation ranon-javatra, noho izany dia ny valva fanaraha-maso azo antoka ampiasaina amin'ny fanerena avo lenta, ny mpanjifa dia afaka misafidy multi -Mekanisma disphragm lohataona na actuator pneumatic, sns.
