Shut-off valve GLO Fig. 215C, DN50 PN16, ductile iron EN-GJS-400-18-LT, construction: 71, stem-to-bonnet connection – detachable – screw, stem, regulating mushroom, and body ring – stainless steel, without opening indicator 215C050C71

The ZGLO Fig. 215C shut-off valve is a reliable solution for flow regulation in diverse systems. Manufactured from high-quality ductile iron EN-GJS-400-18-LT, it ensures durability and corrosion resistance, making it an ideal choice for both professional installers and end users. This model, with a nominal diameter DN50 and nominal pressure PN16, performs excellently in water, steam, and industrial systems.

The valve’s design has been carefully engineered for ease of installation and maintenance. The detachable connection between the stem and the disc, secured by a screw, allows quick access to internal components during servicing. A critical feature is the use of stainless steel for the stem, regulating disc, and body ring—ensuring resistance to aggressive media and long-term reliability. The absence of an opening indicator simplifies the design and minimizes failure risk.

The valve complies with stringent European standards, including the Pressure Equipment Directive 97/23/EC and carries CE marking for diameters from DN32. It has passed testing and certification in accordance with EN 12266-1, confirming its high quality and operational safety. Flanges are machined in compliance with EN 1092-2 for body material group A, and the face-to-face dimension conforms to Series 1 per EN 558-1. Additionally, technical data is compatible with leading calculation software such as Instal-therm, Instal-san, Audytor C.O. 3.8, and Audytor H2O 1.5—significantly simplifying system design and component selection.
