Marine Wafer Check Valve

Wafer Check Valves are designed and manufactured strictly to International Standards API 6D, API 594, ASME B16.34 or equivalent standards. Have the below characteristics.

Short structural length, only 1/4~1/8 of that of traditional flanged check valve.

Low volume, light weight, only 1/4~1/20 of those of traditional flanged check valve.

Quick valve disc closedown, low water hammer pressure.

Applicable for and easily installed for vertical or horizontal pipelines.

Smooth flow passageway and small fluid resistance.

Flexible action and good sealing performance.

Narrow valve travel and small closedown impact.

Integrated structure, simple and compact, in beautiful shape.

Long service life and good reliability.

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.
