Gate valve zGLO Fig. 215C, DN200 PN16, ductile iron EN-GJS-400-18-LT, construction: 43, swing check, loose disc without spring, stem, disc and body ring – bronze 215C200C43

zGLO Shut-off Valve – Reliable Protection for Installations

The zGLO shut-off valve Fig. 215C, with a nominal diameter DN200 and nominal pressure PN16, is a robust solution for protecting water, steam, and industrial process systems. Manufactured from ductile iron EN-GJS-400-18-LT, it ensures long-term, trouble-free operation even under demanding conditions. The swing-check design with a spring-free, loose disc, combined with a bronze stem, disc, and body ring, guarantees effective flow shutoff and prevents backflow of the medium.

This valve is suitable for applications in hot and cold water systems, cooling systems, steam networks, industrial processes, district heating, and power generation. Its versatility makes it an ideal choice for both professional installers and end customers seeking a reliable solution.

Design and Key Features

The valve features high sealing performance (Class A per EN 12266-1), minimizing leakage risks and ensuring safe operation. It has undergone rigorous testing and certification in accordance with EN 12266-1. The flanges are machined in compliance with EN 1092-2 for material group A, and the face-to-face dimension conforms to EN 558-1 Series 1. The valve complies with the Pressure Equipment Directive 97/23/EC and bears the CE marking for DN 32.

Design code 43 indicates a spring-free swing-check valve, where the stem, disc, and body ring are made of bronze – a material resistant to corrosion and abrasion. This construction ensures smooth valve operation and minimizes the risk of mechanical damage.

Compatibility and Design Support

The valve is compatible with leading hydraulic and thermal calculation software: Instal-therm, Instal-san, Audytor C.O. 3.8, and Audytor H2O 1.5 – facilitating quick and accurate system design and component selection. This enables engineers and designers to seamlessly integrate the valve into their projects with precision and efficiency.
