Zawory zwrotne DCV1 i DCV3 są zaworami o konstrukcji płytkowej,
przystosowanymi do zabudowy międzykołnierzowej. Konstrukcja
taka zapewnia znaczne zmniejszenie długości zabudowy w
stosunku do tradycyjnego, grzybkowego zaworu. Zastosowanie
sprężyny powrotnej, zamykającej, pozwala na zabudowę zaworu
płytkowego w dowolnej pozycji. Zawory rodziny DCV są stosowane
dla zapobieżenia przepływom czynnika w niepożądanym kierunku,
w instalacjach pary wodnej, kondensatu, gorącej wody i wielu innych
płynów przemysłowych, również agresywnych (odmiany w wykonaniu
ze stali nierdzewnej).
Wykonanie standardowe zaworów DCV:
- uszczelnienie metal-metal
- sprężyna standardowa
Opcje miękkiego uszczelnienia gniazda:
- Viton (dla olejów, powietrza i innych gazów)
- EPDM (dla wody)
Opcje sprężyn:
- sprężyna wzmocniona (różnica ciśnień otw. zawór ok. 700mbar),
dostępna dla średnic DN15 - 65
- sprężyna Nimonic (dla wysokich temperatur), dostępna w zaworach
DCV3 wszystkich średnic
- bez sprężyny.
