Check Valve with Backflow Prevention – Reliable Protection for Installations

The check valve with shut-off function ZGLO Fig. 215C, in size DN125 and pressure class PN25, is a versatile device combining the functions of a check valve and a shut-off valve. Its design ensures effective protection against reverse flow of the medium, while also enabling complete isolation of the supply. Manufactured from ductile cast iron, it guarantees long-term, trouble-free operation even under demanding conditions.

Design and Materials – Key to Durability

The valve features a well-engineered design utilizing high-quality materials. The spring-free floating disc, combined with a brass stem, bronze disc, and bronze body ring, ensures tight sealing and smooth operation. The body, made of ductile cast iron (EN-GJS-400-18-LT 5.3103), exhibits high resistance to corrosion and mechanical damage. Flanged connections simplify installation and integration with existing infrastructure.

Applications and Benefits

This type of valve finds wide application across various industrial sectors and building installations. It performs reliably wherever protection against backflow and manual flow shut-off are required. Thanks to its design, this valve is particularly recommended for applications where reliability and durability are critical. The ability to manually shut off flow makes it more versatile than a standard check valve—saving space and reducing installation costs.
