Shut-off valve GLO Fig. 215 DN20 PN16, gray cast iron EN-GJL-250, design: 91, stem-to-bonnet connection – detachable – screw, stem, regulating mushroom, and body ring – stainless steel, with opening indicator 215A020C91

Shut-off Valve – Reliable Isolation for Installations

The shut-off valve ZGLO Fig. 215 is a robust solution for flow shut-off in a variety of installations. Manufactured from gray cast iron EN-GJL-250, it ensures durability and corrosion resistance. Designed for use with water, steam, and industrial processes, it performs reliably in both residential buildings and demanding industrial environments.

Construction and Materials – Key to Longevity

The valve’s design combines a cast iron body with components made from stainless steel. The stem, control disc, and seat ring are all manufactured from stainless steel, guaranteeing corrosion resistance and long-term, trouble-free operation. The connection between the stem and disc is detachable and secured with a screw, facilitating servicing and component replacement. The opening indicator allows for quick visual verification of the valve’s position.

• Cast iron body (EN-GJL-250) ensures strength and pressure resistance.
• Stainless steel moving parts minimize corrosion risk and ensure extended service life.
• Detachable stem-disc connection simplifies maintenance and repairs.
• Opening indicator enables rapid identification of valve status.
• Compliance with the Pressure Equipment Directive 97/23/EC and CE marking (for DN 32) confirm safety and product quality.

Applications and Compliance with Standards

This valve is suitable for use in:

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

It meets the requirements of EN 12266-1 (high tightness class A), EN 1092-2 (flange facing), and EN 558-1 (face-to-face length series 1). It can be used in systems rated up to PN 16 and with steam. This makes it a versatile valve component suitable for a wide range of applications. Additionally, the valve’s technical data is available in popular engineering software libraries such as Instal-therm, Instal-san, Audytor C.O. 3.8, and Audytor H2O 1.5, facilitating professional system design.
