Check Valve with Backflow Prevention – Reliable Protection for Installations

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 supply. The valve’s design features a cylindrical stem bushing, simplifying maintenance and distinguishing it from standard shut-off valves.

The ZGLO Fig. 215C valve, with a nominal diameter DN32 and nominal pressure PN25, is constructed from high-quality materials ensuring durability and reliability. The body is made of ductile iron, providing resistance to corrosion and mechanical damage, while internal components — a brass stem, bronze disc, and body ring — ensure tight sealing and smooth operation. Flanged connections facilitate easy installation into existing piping systems.

Construction and Materials:

• Body: Ductile iron (EN-GJS-400-18-LT 5.3103, formerly JS1025) — ensures strength and resistance to environmental conditions.
• Stem: Brass — corrosion-resistant and ensures smooth valve operation.
• Disc and Body Ring: Bronze — guarantees sealing and minimizes risk of mechanical damage.
• Design: Floating disc with spring — enables fast and reliable closure; the spring assists in returning the valve to the open position.
• Connections: Flanged — allow for easy installation and removal within pipeline systems.

This valve is suitable for various industrial and building installations where protection against backflow and the ability to isolate the medium are required. This is especially critical in systems where reverse flow could cause damage or pose a safety risk. Designed for operation at nominal pressure PN25, it is appropriate for most standard applications.
