The V209 dual-plate check valve is one of the most compact non-return valve designs, engineered with a wafer-type body and short face-to-face length, making it ideal for installations where space, weight and efficiency are critical.

Thanks to its optimized internal geometry, the valve provides excellent hydrodynamic performance with very low pressure loss. The lightweight construction offers clear advantages during installation, transportation and storage, reducing overall project costs.

When fluid enters the valve, system pressure causes the dual plates to open smoothly, compressing the internal springs. As soon as the flow stops or reverses, the springs return to their original position, ensuring a fast and reliable closure. This spring-assisted mechanism minimizes reverse flow and significantly reduces the risk of water hammer.

The valve is suitable for horizontal and vertical installation. With properly selected springs, it can be mounted in any position, providing flexibility in pipeline design. The stainless steel shaft ensures high resistance to corrosion and long service life, while the self-seating design reduces wear on the seat surfaces.

Designed for liquids, gases and steam, the V209 dual-plate check valve is widely used in heating, cooling, air conditioning and industrial systems where dependable backflow prevention and energy efficiency are required.

Hydrostatic testing is performed according to EN 12266-1, with seat test pressure at PN × 1.1 and shell test pressure at PN × 1.5, ensuring operational safety and compliance with international standards.
