Shut-off valve zGLO Fig. 215C, DN20 PN16, ductile iron EN-GJS-400-18-LT, design: 31, shut-off and check, loose mushroom with spring, stem, mushroom and body ring – stainless steel 215C020C31

The shut-off valve zGLO Fig. 215C is a reliable solution for diverse applications, from water systems to industrial and district heating technologies. Manufactured from ductile iron EN-GJS-400-18-LT, it offers high mechanical strength and excellent corrosion resistance. This model, in version 31, features a spring-loaded loose disc and internal components—stem, disc, and body ring—made of stainless steel, ensuring long-term, trouble-free operation.

This valve is designed for use in hot, cold, and cooling water systems, as well as steam systems. It complies with the Pressure Equipment Directive 97/23/EC and carries CE marking for diameters from DN 32. Thanks to testing and certification in accordance with EN 12266-1, it guarantees high leak-tightness (Class A). Flanges are drilled in compliance with EN 1092-2 for body material group A, and the face-to-face dimension conforms to Series 1 of EN 558-1.

The use of stainless steel in critical internal components minimizes corrosion risk and ensures durability even under harsh operating conditions. The combined shut-off and check valve function simultaneously prevents reverse flow and isolates the medium supply. This makes it a versatile device suitable for both industrial and building installations. Additionally, technical data for this product are available in popular engineering software libraries such as Instal-therm, Instal-san, Audytor C.O. 3.8, and Audytor H2O 1.5, facilitating design and selection of the optimal solution for specific requirements.

Key features:

• Constructed from ductile iron EN-GJS-400-18-LT, ensuring high mechanical strength and resistance to cracking.
• Internal components made of stainless steel guarantee corrosion resistance and extended service life.
• Shut-off and check valve design combines flow isolation with protection against medium backflow.
• Compliance with EN standards (EN 12266-1, EN 1092-2, EN 558-1) and the Pressure Equipment Directive 97/23/EC confirms safety and reliability.
• Broad application range — suitable for water, steam, industrial processes, as well as power and district heating systems.
• Operates at a maximum working pressure of 16 bar (PN 16).
• Spring-loaded loose disc ensures reliable sealing and easy valve maintenance.

The zGLO Fig. 215C valve is an ideal choice for installers seeking a robust, long-lasting component for heating, water supply, and industrial process systems. Its solid construction and compliance with current standards ensure safe and efficient operation over an extended service life.
