Gate valve GLO Fig. 215 DN65 PN16, gray cast iron EN-GJL-250, design: 43, check-return valve, loose disc without spring, stem, disc and body ring – bronze 215A065C43

zGLO Isolation Valve – Reliable Shut-off for Diverse Installations

The zGLO isolation valve Fig. 215 is a robust solution for precise flow shut-off in water, steam, and industrial process systems. Manufactured from durable gray cast iron EN-GJL-250, it ensures long-term, trouble-free operation even under demanding conditions. The design features a spring-free loose disc coupled with a bronze stem, disc, and body ring, guaranteeing high sealing performance and minimizing leakage risk.

This valve is particularly valued for its versatility—it performs excellently in both hot and cold water systems, as well as in steam applications and demanding industrial, district heating, and power generation environments. Compliance with the Pressure Equipment Directive 97/23/EC and CE marking (for DN 32) ensures its safety and conformity with applicable standards.

Design and Application

The Fig. 215 valve features a simple design that facilitates easy installation and maintenance. Flanges are machined in accordance with EN 1092-2, enabling seamless integration into existing systems. Installation length complies with EN 558-1 (Series 1), ensuring compatibility with most standard systems. The use of bronze for internal components (stem, disc, and body ring) enhances corrosion resistance and ensures smooth valve operation.

Applications include:

• Hot, cold, and cooling water systems
• Steam systems
• Industrial processes
• District heating
• Power generation
