Dual Plate Check Valve
The Berzico Dual Door Check Valve is an all-purpose non-return valve that is much stronger and lighter in weight due to the compact design when compared to a conventional Swing Check Valve or Lift Check Valve.
BERZICO dual door check valves are designed to prevent back flow where systems are made to allow flow in one direction and prevent flow in the opposite direction. The valves are recommended for clean liquids, air, and gases.
Dual Door check valves are equipped with a spring for fast, non-slam shut off against the elastomer or metal seat. The dual doors automatically open when the downstream flow creates the required
pressure in the off-seating direction. When the flow reduces, the torsion of the spring will
automatically close the doors to prevent a flow reversal and minimize system surges and water
