Shut-off valve GLO Fig. 215C, DN20 PN16, ductile iron EN-GJS-400-18-LT, construction: 91, stem-to-disc connection – detachable – screw, stem, regulating disc, and body ring – stainless steel, with opening indicator 215C020C91

Shut-off Valve – Reliable Shut-off for Pipelines

This shut-off valve from the zGLO Fig. 215C series is a robust solution for precise flow shut-off in diverse installations. Manufactured from high-quality spherical cast iron EN-GJS-400-18-LT, it ensures durability and excellent corrosion resistance. Designed for operation at PN16 pressure and DN20 diameter, it performs reliably in water, steam, and demanding industrial applications.

Design and Materials – Key to Long-Term Reliability

The valve features a thoughtfully engineered design combining strength and functionality. The separable stem-to-bonnet connection, secured by a screw, simplifies maintenance and component replacement. Critical components—the stem, mushroom, and body ring—are made from stainless steel, guaranteeing corrosion resistance and long-term performance even under harsh conditions. An opening indicator enables quick visual verification of the valve’s position, enhancing safety and user convenience.

Applications and Compliance with Standards

This valve is widely used in:

• Hot and cold water systems
• Cooling systems
• Steam systems
• Industrial processes
• District heating and power generation systems

It complies with the Pressure Equipment Directive 97/23/EC and carries CE marking (for DN 32). Testing and inspections have been conducted in accordance with EN 12266-1, confirming its high quality and reliability. Flanges are machined in compliance with EN 1092-2 for body material group A, and the face-to-face dimension conforms to Series 1 per EN 558-1. Leakage class A per EN 12266-1 ensures minimal medium loss.

Additionally, the valve’s technical data is integrated into popular engineering software libraries: Instal-therm, Instal-san, Audytor C.O. 3.8, and Audytor H2O 1.5, facilitating seamless design integration for professionals.
