Check Valve with Backflow Prevention – Reliable Protection and Flow Control

This check valve combines the functions of backflow prevention and complete flow shut-off. It is the ideal solution wherever both system protection and precise control over the process are required. The valve’s design, featuring a spring-loaded free-floating disc, stem, and body ring made of stainless steel, ensures long-term, trouble-free operation even under demanding conditions. The ductile iron body guarantees strength and corrosion resistance.

Construction and Applications

This valve features flanged connections, simplifying installation and removal in existing systems. The free-floating disc with spring enables rapid and reliable flow shut-off while minimizing the risk of mechanical damage. Valves of this type are widely used in water, heating, industrial, and sanitary systems. They perform equally well in new installations and during upgrades of existing systems.

Key Features and Benefits

• Multifunctional: Combines check valve and isolation valve functions — one device performs two roles.
• Durability: Internal components made of stainless steel provide excellent corrosion resistance and extended service life.
• Strength: Ductile iron body ensures resistance to high pressure (PN25) and mechanical damage.
• Easy Installation: Flanged connections simplify installation and maintenance.
• Safety: Spring-loaded disc ensures positive valve closure, protecting the system from backflow.
• Wide Application Range: Ideal for water, heating media, and industrial applications.

The Fig. 215C check valve with backflow prevention is a robust solution for professionals and users who value reliability and longevity. Its versatility ensures application across a wide range of systems, delivering safety and efficient operation.
