Shut-off valve zGLO Fig. 215 DN150 PN16, gray cast iron EN-GJL-250, construction: 08, stem-to-bonnet connection – detachable screw, stem, bonnet, and body ring – stainless steel, bonnet seal – PTFE 215A150C08

Gate Valve – Reliable Flow Isolation in Demanding Installations

The Zetkama zGLO type 215 gate valve is a proven industrial valve designed for effective flow isolation across a wide range of applications. Its construction, based on a gray iron body and stainless steel internal components, ensures durability and corrosion resistance. The valve is suitable for use in systems carrying steam, hot and cold water, and compressed air, making it a versatile solution. Compliance with European standards enables its use in both new and upgraded systems.

Construction and Materials – Key to Long Service Life

The valve features a robust design. The body is manufactured from gray iron EN-GJL-250, providing high mechanical strength and excellent corrosion resistance. Critical internal components—the stem, disc, and body seat—are made of stainless steel, further enhancing resistance to aggressive media. The disc seal is made of PTFE, ensuring tightness and minimizing leakage risk. The stem-to-disc connection is detachable via a screw, facilitating maintenance and component replacement. Valve flanges are machined in accordance with EN 1092-2 for material group A, ensuring compatibility with existing piping systems.

Applications and Standards Compliance

This valve is widely used in:

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

It complies with the Pressure Equipment Directive 97/23/EC and carries CE marking for nominal diameters from DN 32. Testing and inspections conducted in accordance with EN 12266-1 confirm the product’s high quality and reliability. The face-to-face dimension conforms to EN 558-1 Series 1. The valve is also compatible with popular engineering software such as Instal-therm, Instal-san, Audytor C.O. 3.8, and Audytor H2O 1.5—technical data is available in their libraries. Class A leakage rating per EN 12266-1 guarantees minimal medium loss and safe operation.
