The Series F16 Dual Plate Wafer Type Check Valve is a high-performance flow control solution engineered for industrial efficiency. Designed with a compact wafer-style body, this valve provides a reliable non-return mechanism that prevents backflow, ensuring the safety and integrity of your piping system while minimizing pressure drop across the line.
Constructed from premium materials including Cast Iron and Ductile Iron, the Series F16 is versatile enough to handle a wide range of media. With its dual-plate design, it offers a shorter face-to-face dimension compared to traditional swing check valves, making it an ideal choice for space-constrained installations in general equipment manufacturing and fluid transport.

Frequently Asked Questions
Dual plate check valves are more compact, lighter, and offer a lower pressure drop. They also close faster, which significantly reduces the impact of water hammer in industrial piping.
For higher temperature and chemical resistance, Viton is generally recommended, whereas EPDM is excellent for steam and water applications.
Yes, the Series F16 is designed for versatility and can be installed in both horizontal and vertical lines, provided the flow is in the correct direction.
The body materials comply with international standards including ASTM A126 (Cast Iron), ASTM A536 (Ductile Iron), DIN 1691, and EN 1561.
The wafer design allows the valve to be sandwiched between two flanges, reducing the total length of the piping run and making replacement much faster.
Nickel plating provides an essential layer of corrosion protection, increasing the operational lifespan of the disc when exposed to mildly corrosive fluids.
