Check Valve with Backflow Prevention – Reliable Protection for Installations

The zGLO Fig. 215C check valve is a device combining the functions of a check valve and a shut-off valve. It provides effective protection against reverse flow of the medium and allows complete flow isolation when required. This is particularly critical in systems where flow direction is essential for proper operation.

This valve features a robust construction and high manufacturing quality. The body, made of ductile iron, ensures resistance to pressure and corrosion, while internal components — a brass stem, bronze disc, and bronze seat ring — guarantee tightness and long-term reliability. The 32 design, characterized by a floating disc with a spring, enables smooth operation and minimizes the risk of damage caused by water hammer.

The valve has a nominal diameter of 40 mm and is rated for a nominal pressure of PN 25. The body is made of ductile iron, the stem of brass, and the disc and seat ring of bronze. It features flanged connections.

The zGLO Fig. 215C valve is suitable for a wide range of industrial and building installations, including:

• Water supply and sewage systems
• Central heating systems
• Industrial refrigeration circuits
• Technological processes requiring protection against backflow

The valve’s cylindrical stem design facilitates easy installation and disassembly, which is especially important during system maintenance. The availability of multiple variants allows precise adaptation to specific operating conditions and medium types. These valves are offered in various nominal diameters and pressure classes, ensuring flexibility in hydraulic system design. Selecting the appropriate variant enables cost optimization and long-term reliable protection of the installation.
