Gate valve GLO Fig. 215 DN125 PN16, gray cast iron EN-GJL-250, construction: 42, swing-check type, loose disc without spring, stem – brass, disc seat ring – bronze 215A125C42

Cast Iron Isolation Valve – Reliable Shut-off for Pipelines

The isolation valve ZGLO Fig. 215 DN125 PN16 is a robust solution for flow shut-off in diverse piping systems. Manufactured from durable gray cast iron (EN-GJL-250), it ensures long-term, trouble-free operation even under demanding conditions. The shut-off and check design, featuring a spring-free loose disc, guarantees effective medium shut-off and prevents backflow.

Construction and Applications

This valve is designed for use with hot water, cold water, cooling water, and steam. It performs reliably in industrial, district heating, and power generation systems. The construction type 42, with a brass stem and bronze disc seat on the body, provides excellent corrosion resistance and durability. Valve flanges are machined in accordance with EN 1092-2 for body material group A, facilitating installation and ensuring joint tightness. Face-to-face length complies with EN 558-1 Series 1.

Key Features and Benefits

• High Tightness: Class A leakage rating per EN 12266-1 ensures minimal medium loss and safe system operation.
• Durability and Resistance: Gray cast iron body (EN-GJL-250) combined with high-quality internal components (brass, bronze) guarantee extended service life.
• Versatility: Suitable for applications involving water, steam, and various industrial processes.
• Standards Compliance: Meets requirements of the Pressure Equipment Directive 97/23/EC and carries CE marking for DN 32.
• Software Compatibility: Technical data is available in leading design software: Instal-therm, Instal-san, Audytor C.O. 3.8, and Audytor H2O 1.5 – simplifying system design and component selection.
• Safety: Shut-off and check function protects the system against backflow, minimizing risk of damage and failure.

The valve operates at a maximum working pressure of 16 bar (PN 16). Its simple, streamlined design facilitates operation and maintenance. This proven industrial valve is ideal for both new installations and modernization of existing systems.
