Gate valve GLO Fig. 215 DN250 PN16, gray cast iron EN-GJL-250, design: 31, check-return, loose disc with spring, stem, disc and body ring – stainless steel 215A250C31

zGLO Shut-off Valve – Reliable Flow Isolation

The zGLO Fig. 215 shut-off valve is a robust solution for precise flow isolation in water, steam, and industrial process systems. Manufactured from high-quality gray cast iron EN-GJL-250, it ensures durability and corrosion resistance. The design features a loose mushroom with a spring, combined with a stainless steel stem, mushroom, and body ring, guaranteeing tight sealing and reliable operation even under demanding conditions. Suitable for media such as hot and cold water, steam, and industrial applications in heating and power generation.

Construction and Application

This valve features flanges drilled according to EN 1092-2 for body material group A and body length compliant with EN 558-1 Series 1, ensuring simple and efficient installation. CE marking (for DN ≥32) confirms compliance with the Pressure Equipment Directive 97/23/EC, critical for overall system safety. Notably, the valve achieves high leak-tightness class A per EN 12266-1, minimizing leakage risk.
