Kistenmacher Dual Plate Wafer Type Check Valve, EGK-VE-210-DN250, Ductile Iron, 1.6 Mpa, 10 Inch

The Kistenmacher Dual Plate Wafer Type Check Valve (EGK-VE-210-DN250) is a robust and space-efficient flow-control solution engineered to provide dependable backflow prevention and long-term performance in demanding industrial pipeline systems. Designed for a 10-inch (DN250) nominal bore and rated for PN16/1.6 MPa (16 bar) working pressure, this check valve is ideally suited for water supply networks, HVAC systems, fire protection lines, industrial process piping, and general utility services where reliable one-directional flow control is essential. At the core of this valve is its dual plate (double disc) design, which ensures rapid response to changes in flow direction. During normal forward flow, the two spring-assisted plates open smoothly, allowing fluid to pass with minimal pressure loss. When flow velocity drops or reverses, the integrated springs immediately force the plates to close, effectively preventing backflow. This fast and balanced closing action helps to reduce water hammer, vibration, and stress on pumps, pipes, and other downstream equipment, thereby enhancing overall system safety and longevity. The valve body is manufactured from high-strength ductile iron, offering excellent mechanical durability, impact resistance, and pressure-handling capability compared to conventional cast iron. This makes the EGK-VE-210-DN250 particularly well-suited for high-duty industrial environments where reliability under pressure fluctuations is critical. Internal components such as the plates, hinge pins, and springs are typically made from corrosion-resistant stainless steel, ensuring smooth operation, reduced wear, and long service life even under frequent cycling conditions. Its wafer-type construction allows the valve to be installed directly between two matching flanges, eliminating the need for additional pipe fittings or extended face-to-face space. This compact design significantly reduces installation weight and cost while making the valve ideal for retrofits, tight plant layouts, and systems where space optimization is a priority. The valve can be installed in both horizontal and vertical pipelines (with upward flow), providing flexibility across a wide range of applications.
