Shut-off valve zGLO Fig. 215C, DN50 PN16, ductile iron EN-GJS-400-18-LT, execution: 33, shut-off and check, loose mushroom with spring, stem, mushroom and body ring – bronze 215C050C33

The zGLO Fig. 215C check valve is a reliable solution for protecting installations against backflow and overpressure. Manufactured from ductile iron EN-GJS-400-18-LT, it ensures long-term, trouble-free operation under demanding conditions. This model, with a nominal diameter DN50 and nominal pressure PN16, is suitable for a wide range of applications—from hot and cold water systems, through steam lines, to industrial processes, district heating, and power generation.

The valve features high tightness (Class A per EN 12266-1), guaranteeing minimal medium loss and safe operation. Its design incorporates a spring-loaded loose disc combined with a bronze stem, disc, and body ring, ensuring smooth operation and excellent corrosion resistance. Additionally, the valve complies with the Pressure Equipment Directive 97/23/EC and carries the CE marking for diameters DN32 and larger.

Design and Application

The zGLO Fig. 215C valve is engineered for easy installation and maintenance. Flanges are machined in accordance with EN 1092-2, facilitating seamless integration into existing systems, while the installation length conforming to EN 558-1 (Series 1) allows for straightforward replacement of older models. The use of bronze in critical internal components enhances resistance to chemical corrosion and abrasion, extending the device’s service life. Available as a check valve, it performs two functions simultaneously: shutting off medium flow and preventing reverse flow.

Practical Advantages:

• Versatility: Suitable for various media (water, steam) and industries (industrial, district heating).
• Durability: Ductile iron EN-GJS-400-18-LT ensures resistance to high pressures and temperatures.
• Tightness: Class A sealing guarantees minimal medium loss and enhanced system safety.
• Standards Compliance: Meets requirements of the Pressure Equipment Directive 97/23/EC and European standards (EN), confirming high product quality.
• Compatibility: Technical data is available in popular engineering software libraries (Instal-therm, Instal-san, Audytor C.O. 3.8, Audytor H2O 1.5), simplifying system design.
• Easy Integration: Machined flanges per EN 1092-2 ensure compatibility with existing pipeline systems.

This valve is a robust choice for professional installers seeking a reliable component for their projects, as well as for end-users who value safety and durability in their home or business installations.
