Pneumatic kontwòl kriyojenik modèl valv seleksyon
Ranje Tanperati : Dapre kondisyon yo ki espesifik tanperati ki ba, chwazi modèl la valv ki ka adapte yo ak seri a tanperati. Valv kontwòl kriyojenik anjeneral bezwen pou kapab kenbe tèt ak tanperati ki ba anpil, se konsa tiyo ki fèt ak materyèl espesyal bezwen yo dwe chwazi.
Kalite Valv : Dapre senaryo aplikasyon espesifik ak kondisyon kontwòl yo, chwazi kalite valv ki apwopriye a, tankou valv glòb, reglemante valv, valv boul, elatriye diferan kalite tiyo gen karakteristik kontwòl diferan ak chenn aplikasyon.
Mòd kontwòl : Chwazi Valv kontwòl Pneumatic dapre bezwen aktyèl, ki ka sèl aji (yon sèl-fason kontwòl) oswa doub aji (pozitif ak kontwòl negatif). Dapre kondisyon ki nan sistèm nan kontwòl, chwazi mòd nan kontwòl ki apwopriye yo.
Ou ka konsidere faktè sa yo pi wo a, ou ka chwazi apwopriye konpwesyon ki gen konpwesyon modèl la valv kontwòl kriyojenik. Konpayi nou an tou gen lòt pwodwi: valv kontwòl elektrik, valv boul konpwesyon, valv boul elektrik, konpwesyon valv papiyon , elatriye, Byenveni nan konsilte.
