(3). - Spring: alloy
(4). - Hinge pin: Stainless steel
(5). - Plug: cast steel
3. Nominal Diameter ＆ Pressure
Diameter: 50~600
Pressure: 150
4. Features
Wafer design: The wafer design of the valve allows for easy installation between flanges, without the need for additional support or hardware. This makes it a cost-effective and efficient option for many marine applications.
Spring-loaded disc: The valve features a spring-loaded disc that opens in the direction of flow, allowing fluids to pass through while preventing backflow. The spring ensures that the disc returns to its closed position quickly and reliably, even in the presence of high flow rates.
Durable materials: Marine class 150 wafer check valves are typically made from durable materials such as cast iron, stainless steel, or bronze, which can withstand the harsh marine environment and resist corrosion.
