VAN MỘT CHIỀU CÁNH BƯỚM DK VALVE - Dual plate check valve

Dual plate check valve

Retainer-less design with no external body penetrations eliminating the possibility of outside leakage
Light weight and compact design reduce pipe supports, simplifies piping, easier, less costly installation
Spring-loaded, double disc design has low cracking pressure and provides high responsiveness.
Efficient and positive sealing under most flow and pressure conditions.
Valve closes before flow reversal at zero velocity and minimizes water hammer effect.
Low pressure drop and reduced energy loss irrespective of pressure rating
Long life and trouble-free opreation.
