Shut-off valve zGLO Fig. 215C, DN40 PN25, design 03: stem-to-bonnet connection – detachable – screw, stem, bonnet. Body – ductile iron. 215C040D03

Shut-off mushroom valves, such as this model from the zGLO series Fig. 215C, serve the primary function of fully opening or closing the flow of medium in a system. This specific model, with a diameter DN40 and nominal pressure PN25, is designed for applications requiring reliable flow isolation. The design featuring a threaded connection between the stem and mushroom ensures tightness and durability.

The valve features a body made of ductile iron (EN-GJS-400-18-LT), guaranteeing pressure resistance and corrosion resistance. Flanged connections (compliant with EN 1092 standard) simplify installation and integration with existing infrastructure. Designation 03 indicates a detachable stem-to-mushroom connection via screw, facilitating servicing and replacement of sealing components. The stem is made of brass, while the mushroom and seat ring are made of bronze, ensuring excellent resistance to wear and corrosion.

This valve is suitable for a wide range of applications, including water, steam, compressed air, oil, and glycol systems. It can also be used with glycerin. Thanks to its construction and materials, the valve is rated for operation at temperatures up to +350°C. However, it is essential to verify material compatibility with the medium—detailed information on chemical resistance can be found in the manufacturer’s documentation from Zetkama.

Key features to note:

• Durable construction: Ductile iron body ensures high mechanical strength and corrosion resistance.
• Leak-tight sealing: Detachable stem-to-mushroom connection guarantees a secure flow shut-off.
• Versatility: Suitable for various media (water, steam, compressed air, oil, glycol).
• Easy installation: Flanged connections simplify integration into existing systems.
• Serviceability: Design allows for easy replacement of sealing components.

This valve is ideal for professional installers seeking a reliable solution for industrial and commercial systems, as well as end-users requiring a robust valve for residential installations. It provides effective medium isolation, minimizing the risk of failures and downtime.
