Shut-off valve GLO Fig. 215 DN15 PN16, gray cast iron EN-GJL-250, construction: 91, stem-to-bonnet connection – detachable – screw, stem, regulating disc, and body ring – stainless steel, with opening indicator 215A015C91

The ZGLO Fig. 215 shut-off valve is a reliable solution for flow regulation 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 detachable stem-to-disc connection (screw), simplifying servicing and internal component replacement.

This valve is suitable for applications in hot and cold water systems, chilled water circuits, steam systems, industrial processes, district heating, and power generation. Thanks to its high tightness class (Class A per EN 12266-1), it minimizes medium losses and ensures safe system operation. Designed for nominal pressure PN 16, it is compatible with flanges machined according to EN 1092-2 for material group A and has installation length compliant with EN 558-1 Series 1.

• Robust construction: Body made of gray cast iron EN-GJL-250 provides resistance to corrosion and mechanical damage.
• High tightness: Class A tightness per EN 12266-1 ensures minimal medium leakage and safe system operation.
• Versatile application: Ideal for water, steam, and industrial process installations.
• Easy maintenance: Detachable stem-to-disc design allows quick replacement of internal components without removing the entire valve.
• Standards compliance: Meets the requirements of the Pressure Equipment Directive 97/23/EC and carries CE marking for DN ≥32.
• Durable materials: Stem, regulating disc, and body ring are made of stainless steel, ensuring corrosion resistance and extended service life.
• Position indicator: Enables visual confirmation of valve position without manual inspection or opening—useful for installers during commissioning and end-users during operation.

The valve is compatible with popular calculation software such as Instal-therm, Instal-san, Audytor C.O. 3.8, and Audytor H2O 1.5, facilitating design and selection for specific system requirements. Execution 91 features a detachable stem-to-disc connection via screw, with stem, regulating disc, and body ring all manufactured from stainless steel to ensure maximum durability and corrosion resistance.
