Shut-off valve GLO Fig. 215 DN25 PN16, gray cast iron EN-GJL-250, construction: 71, stem-to-bonnet connection – detachable – screw, stem, regulating mushroom, and body ring – stainless steel, without opening indicator 215A025C71

Isolation Valve – Reliable Flow Shut-off

The isolation valve ZGLO Fig. 215 is a robust solution for precise flow shut-off 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. This model, with a nominal diameter DN25 and nominal pressure PN16, is particularly recommended for industrial, district heating, and power generation applications.

Construction and Materials – Guarantee of Durability

The key feature of this valve is the detachable connection between the stem and the mushroom, secured by a screw. The stem, regulating mushroom, and body ring are made of stainless steel, providing excellent corrosion resistance and extended service life. The absence of an opening indicator simplifies the design and minimizes the risk of failure. The use of high-quality materials ensures reliability and reduces operational costs.

Application and Compliance with Standards

This valve performs excellently in hot and cold water systems, cooling circuits, and steam systems. It complies with the Pressure Equipment Directive 97/23/EC and carries the CE marking for DN 32, confirming its safety and conformity with European standards. Testing and inspections conducted in accordance with EN 12266-1 ensure high quality and tightness (Class A per EN 12266-1). Additionally, flanges are machined in compliance with EN 1092-2 for body material group A, and the face-to-face dimension conforms to EN 558-1 Series 1.
