Gate valve GLO Fig. 215 DN300 PN16, gray cast iron EN-GJL-250, design: 41, check-return, loose disc without spring, stem, disc and body ring – stainless steel 215A300C41

Check valve with shut-off function – reliable protection for installations

This check valve with shut-off function, marked as Fig. 215, is a robust solution for protecting installations against backflow and enabling easy shut-off of medium flow. Manufactured from high-quality gray cast iron EN-GJL-250, it ensures durability and corrosion resistance. Designed for diameters DN300 and pressure rating PN16, it is ideal for both industrial applications and residential construction.

Design and application

The valve features a spring-free mushroom disc design, ensuring smooth operation and minimizing the risk of damage. Critical components—the stem, disc, and body ring—are made from stainless steel, guaranteeing resistance to aggressive media and long-term reliability. This valve is suitable for hot water, cold water, and cooling systems, as well as steam systems and industrial processes. It performs reliably in district heating and power generation.

• Wide range of applications: Ideal for water, steam, and various industrial media.
• Durable construction: Cast iron body (EN-GJL-250) ensures strength and corrosion resistance.
• Stainless steel components: Stem, disc, and body ring provide longevity and resistance to aggressive media.
• Check and shut-off function: Protects the system against backflow and allows easy isolation of medium flow.
• Compliance with standards: Meets requirements of the Pressure Equipment Directive 97/23/EC and carries CE marking (for DN 32).
• High tightness: Leakage class A per EN 12266-1 ensures minimal medium loss.
• Software compatibility: Technical data is available in calculation software libraries: Instal-therm, Instal-san, Audytor C.O. 3.8, and Audytor H2O 1.5 — simplifying design and selection.

The valve is compatible with flanges according to EN 1092-2 for body material A and has installation length compliant with EN 558-1 Series 1. This ensures simple and intuitive installation for both professionals and less experienced users. It provides effective protection against overpressure and backflow — just like most circuit breakers in this class.
