Shut-off valve GLO Fig. 215 DN200 PN16, gray cast iron EN-GJL-250, construction: 71, stem-to-bonnet connection – detachable – screw, stem, regulating disc, and body ring – stainless steel, without opening indicator 215A200C71

Valve designed for demanding installations

This shut-off valve ZGLO Fig. 215 is a robust solution for precise flow isolation in a variety of systems. Manufactured from durable gray cast iron EN-GJL-250, it ensures reliability and long service life even under harsh operating conditions. A nominal diameter DN200 and pressure class PN16 make it an ideal choice for medium- and high-capacity installations.

This valve stands out due to its meticulous construction and thoughtful design. The detachable connection between the stem and the disc, achieved via a screw, enables easy disassembly and servicing. A key feature is the use of stainless steel for the stem, regulating disc, and body ring—guaranteeing corrosion resistance and long-term sealing integrity. The absence of an opening indicator simplifies the design and minimizes the risk of failure.

Construction and practical application

The valve is suitable for applications in hot and cold water, cooling systems, and steam, as well as in industrial processes, district heating, and power generation. Compliance with the Pressure Equipment Directive 97/23/EC and CE marking (for DN 32) ensures adherence to stringent safety standards. Testing and inspections conducted in accordance with EN 12266-1 confirm its high quality and reliability. Flanges are machined in compliance with EN 1092-2 for body material group A, facilitating installation and integration with existing systems. Face-to-face dimensions conform to EN 558-1 Series 1, ensuring compatibility with other system components.

• Durable materials: Gray cast iron EN-GJL-250 provides resistance to corrosion and mechanical damage.
• Stainless steel components: Use of stainless steel on critical parts (stem, disc, ring) ensures long-term sealing and reliability.
• Wide range of applications: Ideal for water, steam, and various industrial processes.
• Compliance with standards: Meets requirements of the Pressure Equipment Directive 97/23/EC and European standards (EN).
• Compatibility: Flanges machined to EN 1092-2 simplify installation in existing systems.
• Design support: Technical data is available in leading calculation software libraries (Instal-therm, Instal-san, Audytor C.O., Audytor H2O), facilitating the design of heating and sanitary systems.

This valve is not merely a component—it is an investment in system safety and years of trouble-free operation.
