Shut-off Valve – Reliable Isolation for Installations

The shut-off valve ZGLO Fig. 215 is a robust solution for flow shut-off in various systems. Manufactured from gray cast iron EN-GJL-250, it ensures long-term, trouble-free operation even under demanding conditions. Designed for use with hot water, cold water, cooling water, and steam, it is suitable for industrial processes, district heating, and power generation.

Construction and Materials

The valve features a detachable connection between the stem and disc via a screw, facilitating servicing and component replacement. The stem is made of brass, while the regulating disc and body ring are made of bronze. This material combination ensures corrosion resistance and guaranteed sealing. High sealing class (Class A per EN 12266-1) minimizes leakage risk.

Application and Compliance with Standards

The valve complies with the Pressure Equipment Directive 97/23/EC and carries CE marking for DN 32. Flanges are machined in accordance with EN 1092-2 for body material group A, and the face-to-face dimension conforms to Series 1 per EN 558-1. It has successfully passed testing and certification in accordance with EN 12266-1, confirming its safety and reliability.
