TVN V209 Dual-Plate Check valve is one of the most compact check valves. The wafer-type check valves are designed with a short overall length. Their excellent hydrodynamic properties result in very low pressure losses. Their lower weight brings advantages during installation, transport and storage.
When fluid enters the valve, the pressure causes the discs to open, pushing the spring. When the fluid stops, the spring returns to its compressed state, making the discs return to the closed position, ensuring a quick closing.
