Shut-off valve zGLO Fig. 215C, DN200 PN16, ductile iron EN-GJS-400-18-LT, construction: 41, swing check, loose disc without spring, stem, disc and body ring – stainless steel 215C200C41

Gate Valve Made of Spheroidal Graphite Cast Iron – Reliable Shut-off for Demanding Installations

This gate valve made of spheroidal graphite cast iron, with a nominal diameter DN200 and nominal pressure PN16, is a robust solution for industrial and municipal applications. Manufactured from durable spheroidal graphite cast iron EN-GJS-400-18-LT, it ensures long-term, trouble-free operation even under harsh conditions. The valve’s design features a spring-free, gate-and-check mechanism with a floating disc and a steel stem, disc, and body ring, guaranteeing tightness and corrosion resistance.

Construction and Application – Key to Effective System Protection

This valve is suitable for a wide range of applications, including hot and chilled water systems, steam systems, industrial processes, district heating, and power generation. It complies with the Pressure Equipment Directive 97/23/EC and carries CE marking (for DN 32), confirming conformity with European safety standards. Flanges are machined according to EN 1092-2 for material group A, and the face-to-face dimension conforms to EN 558-1 Series 1. Thanks to its high sealing class (Class A per EN 12266-1), it minimizes leakage risks and ensures optimal system performance.

Benefits for Installers and End Users

• Durable Construction: Spheroidal graphite cast iron EN-GJS-400-18-LT offers high mechanical strength and excellent corrosion resistance, resulting in extended valve service life.
• High Sealing Performance: Class A sealing (EN 12266-1) ensures minimal medium loss and safe system operation.
• Versatile Application: Suitable for use with various media, including water and steam, across multiple industrial sectors.
• Compliance with Standards: Conformity with Pressure Equipment Directive 97/23/EC and European norms ensures safe and certified operation.
• Software Compatibility: Technical data is available in leading calculation software libraries (Instal-therm, Instal-san, Audytor C.O. 3.8, Audytor H2O 1.5), simplifying system design.
• High-Temperature Resistance: Internal component materials allow operation at temperatures up to 450°C.
• Gate-and-Check Functionality: Integrated check function prevents backflow of the medium in the system.
