Shut-off valve GLO Fig. 215 DN25 PN16, gray cast iron EN-GJL-250, construction: 31, shut-off and check, loose mushroom with spring, stem, mushroom and body ring – stainless steel 215A025C31

Check Valve with Backflow Function – Reliability and Versatility in One

The Fig. 215 DN25 PN16 gate valve is a robust solution for precise flow control in diverse installations. Manufactured from high-quality gray cast iron EN-GJL-250, it ensures durability and corrosion resistance. The design features a spring-loaded loose disc combined with a stainless steel stem, disc, and body ring, guaranteeing tight sealing and reliable operation. This valve integrates both shut-off and check functions, making it ideal for applications requiring both flow interruption and prevention of medium backflow.

This valve performs excellently in hot and cold water systems, steam lines, as well as industrial, district heating, and power generation applications. Compliance with the Pressure Equipment Directive 97/23/EC and CE marking (for DN 32 and larger) ensures adherence to stringent safety standards. Designed for nominal pressure PN 16 bar, it offers a broad range of applications.

Construction and Materials – Key to Long-Term Durability

The use of stainless steel for internal components – stem, disc, and body ring – significantly enhances resistance to aggressive media and ensures long-term reliability. The cast iron body provides dimensional stability and mechanical strength. Additionally, the valve has undergone rigorous testing and certification in accordance with EN 12266-1, confirming its high quality and operational safety. Flanges are machined in compliance with EN 1092-2 for body material group A, facilitating easy installation in existing systems. Face-to-face dimension conforms to EN 558-1 Series 1.

Practical Benefits for Installers and Users

• Versatility: Combined shut-off and check function eliminates the need for two separate valves, simplifying installation and reducing costs.
• Leak-tightness: High sealing class (Class A per EN 12266-1) minimizes leakage risk and ensures safe operation.
• Compatibility: Compatible with popular calculation software (Instal-therm, Instal-san, Audytor C.O. 3.8, Audytor H2O 1.5), simplifying system design.
• Durability: High-quality materials ensure long service life even under demanding operating conditions.
• Safety: Compliance with Pressure Equipment Directive 97/23/EC and CE marking confirm safe usage (for DN 32 and larger).
• Easy Installation: Machined flanges compliant with EN 1092-2 enable seamless integration into existing piping systems.
