Check Valve with Backflow Prevention – Reliable Protection for Systems

This valve combines the functions of a check valve and a shut-off valve, providing dual protection for the system. It prevents reverse flow of the medium while also enabling complete isolation of the flow. The valve’s design allows for easy identification: it features a cylindrical extension on the stem, located outside the threading of the securing nut.

The ZGLO Fig. 215C valve, with a nominal diameter DN40 and nominal pressure PN25, is constructed from high-quality materials ensuring durability and reliability. Design 41 features a loose poppet without a spring, with the poppet, stem, and body ring all made of stainless steel. The valve body is made of ductile iron – a material resistant to corrosion and mechanical damage.

Construction and Materials:

• Body: Ductile iron – ensures strength and corrosion resistance.
• Poppet, Stem, and Body Ring: Stainless steel – guarantees resistance to aggressive media and long service life of sealing components.
• Design: Loose poppet without spring – minimizes the risk of poppet jamming and facilitates easy replacement when needed.
• Connections: Flanged – enable simple installation and removal within the system.

This valve is suitable for a wide range of industrial and building installations requiring protection against backflow and the ability to shut off the medium. It is particularly recommended for applications involving media requiring high corrosion resistance, thanks to the use of stainless steel in critical structural components. The use of this type of valve ensures safe and efficient system operation over an extended period.
