Check valve FIG.401 DN50 with ball 401D050C55

Ball check valve – reliable installation protection

The Zetkama FIG.401 DN50 ball check valve is an installation component that prevents backflow of the medium. Its construction based on a steel ball coated with NBR ensures a tight seal and minimal flow resistance, which translates to efficient system operation. This is particularly important in water and sewage installations, where backflow can lead to serious problems.

This valve finds application in a wide range of installations, both domestic and industrial. It is suitable for places where reliable operation and protection against unwanted backflow are required. Thanks to the possibility of mounting in horizontal and vertical positions, the valve is easy to adapt to different installation conditions.

Construction and properties

The FIG.401 check valve is characterized by a solid construction with a body and cover made of ductile iron EN GJS-500-7, which guarantees strength and corrosion resistance. The steel ball covered with NBR rubber ensures tightness and long-term operation. The use of this material allows operation with water and sewage, as well as with various chemically neutral agents.

The valve has a body made of ductile iron EN GJS-500-7, which provides mechanical strength and corrosion resistance. The ball made of steel coated with NBR guarantees tightness and minimal flow resistance. The BSP connection allows easy installation in standard threaded installations. The valve is designed to operate at temperatures up to +70°C and at a nominal pressure of PN16. Its nominal diameter is DN50 (2"), which facilitates integration with existing infrastructure.

The valve is also characterized by low pressure losses thanks to a construction ensuring full medium flow and a self-cleaning function that minimizes the risk of the valve being blocked by impurities. In addition, the quiet operation of the valve increases user comfort.

Installation and application

The FIG.401 check valve is intended for installation in pipelines with a nominal diameter of DN50 (2"). Thanks to the BSP threaded connection, its installation is simple and does not require specialized tools. The valve can be mounted both horizontally and vertically, which provides a high degree of freedom in arrangement during installation.

Application:

• Water and sewage installations
• Heating systems
• Industrial installations
• Protection of pumps against backflow of medium
• Irrigation systems
