Check valve flanged type 895 DN50 149B3000

Check valve flanged – reliable installation protection

This flanged check valve, type 895, with a nominal diameter of DN50, is a solid and effective solution to protect the installation against backflow of medium. The GG 25 (GJL-250) cast iron construction ensures durability and corrosion resistance, and the rubber seal guarantees tightness. This valve is used in water and sewage systems, industrial and heating systems, where preventing the backflow of liquids and gases is crucial.

Construction and principle of operation

The valve uses a two-part disc assisted by a spring, which ensures quick and reliable closing. This design minimizes pressure pulsations and dampens hydraulic shocks, protecting installation components from damage. Polished internal surfaces reduce flow resistance, lowering pressure losses and improving the energy efficiency of the system. Flanged mounting simplifies installation and disassembly of the valve, reducing the time required for service and maintenance.

Key features and benefits

• Material durability: The body made of GG 25 (GJL-250) cast iron provides resistance to corrosion and mechanical damage, which translates into a long valve life.
• Fast response: The spring-assisted two-part disc reacts instantly to a change in flow direction, effectively blocking backflow.
• Tightness: The rubber seal provides reliable sealing, minimizing the risk of leaks.
• Easy installation: The flanged design simplifies valve installation and disassembly, saving time and labor costs.
• Resistance to high temperatures: The valve is designed to operate at a maximum temperature of 100°C.
• Compliance with standards: Pressure class PN 16 (device) and PN 10 (flanges) guarantees safe use and compliance with applicable standards.

This valve is an ideal solution for both professional installers and end-users looking for reliable protection of the installation against backflow of medium. Its solid construction and ease of installation make it an investment that pays off.
