Check valve zGLO Fig. 215C, DN25 PN25, construction 33: loose mushroom with spring, stem, mushroom, and shell ring – bronze. Body – ductile iron. 215C025D33

Check Valve with Backflow Prevention – Reliable Protection and Flow Control

The zGLO Fig. 215C check valve is a versatile 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 isolation of the flow when required. This solution is ideal for systems demanding both protection against backflow and the ability to manually shut off the supply.

This valve features a robust construction based on ductile iron—a material renowned for high strength and corrosion resistance. Critical internal components, including the mushroom, stem, and body ring, are made of bronze, ensuring long-term, trouble-free operation. The floating mushroom with spring mechanism ensures rapid response to pressure changes and reliable performance under varying conditions.

Design and Applications

The valve is equipped with flanged connections, simplifying installation and integration into existing systems. Its design allows for easy maintenance and servicing. The cylindrical stem bushing enables precise flow control. Valves of this type are widely used across various industrial sectors and building installations—anywhere protection against backflow and manual flow control are required.

• Body Material: Ductile iron EN-GJS-400-18-LT (formerly JS1025) – ensures high mechanical strength and corrosion resistance.
• Internal Components: Bronze – guarantees durability and reliable operation under diverse conditions.
• Connections: Flanged – facilitate easy installation and system integration.
• Pressure Class: PN 25 – defines the maximum operating pressure of the valve.
• Design: Floating mushroom with spring – ensures rapid response to pressure fluctuations.

The zGLO Fig. 215C valve is a proven choice for professionals and end-users seeking a reliable solution to protect installations against backflow and enable manual flow control.
