Shut-off valve GLO Fig. 215 DN300 PN16, gray cast iron EN-GJL-250, design: 31, swing check, loose disc with spring, stem, disc and body ring – stainless steel 215A300C31

The gate valve with GLO Fig. 215 is a reliable solution for flow regulation of media in diverse installations. Manufactured from high-quality gray cast iron EN-GJL-250, it ensures durability and corrosion resistance. This model, with a nominal diameter DN300 and pressure class PN16, is designed for operation in water, steam, and technological systems.

The valve features a gate-check design with a spring-loaded loose disc. This structural configuration enables effective flow shut-off while minimizing the risk of damage caused by water hammer. The stem, disc, and body ring are made of stainless steel, guaranteeing high corrosion resistance and long-term reliability. Particularly important is the high tightness (Class A per EN 12266-1), ensuring safety and minimizing medium losses.

The valve complies with the Pressure Equipment Directive 97/23/EC and bears the CE marking for DN32, confirming its conformity with European safety standards. Thanks to flanges conforming to EN 1092-2 and an installation length compliant with EN 558-1 Series 1, the valve can be easily installed and integrated into existing systems. It is compatible with popular calculation programs such as Instal-therm, Instal-san, Audytor C.O. 3.8, and Audytor H2O 1.5, and facilitates design and selection of the optimal solution for specific requirements.

• Versatility: Suitable for hot water, cold water, cooling water, and steam systems.
• Durability: Constructed from gray cast iron EN-GJL-250 and stainless steel components, ensuring long service life.
• Safety: Complies with Pressure Equipment Directive 97/23/EC and bears CE marking (for DN32).
• High tightness: Class A tightness per EN 12266-1 minimizes leakage risk and medium losses.
• Compatibility: Technical data available in libraries of calculation programs (Instal-therm, Instal-san, etc.).
• Application across industries: Ideal for industrial processes, district heating, and power generation.

This valve is used in a wide range of installations—from residential central heating systems to advanced industrial processes requiring precise flow regulation. The gate-check design protects the system against media backflow, which is especially critical in systems subject to pressure fluctuations or flow direction changes. Thanks to the spring-loaded loose disc, the valve effectively dampens hydraulic shocks, enhancing safety and extending the lifespan of the entire installation.
