Shut-off valve GLO Fig. 215 DN50 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 215A050C08

Isolation Valve – Reliable Shut-off for Your Installation

This cast iron isolation valve from the 215 series is a robust and proven solution for diverse applications in water, steam, and industrial systems. Manufactured from high-quality gray cast iron EN-GJL-250, it ensures durability and corrosion resistance. The design features a detachable stem-to-bonnet connection (threaded), simplifying servicing and PTFE seal replacement, thereby minimizing downtime. The valve is designed for nominal pressure PN 16 and nominal diameter DN50.

Construction and Application – Key to Efficient Operation

The valve has been engineered for broad application versatility. It performs reliably in hot and cold water, cooling systems, steam networks, industrial processes, district heating, and power generation. Thanks to its high leakage class (Class A per EN 12266-1), it guarantees minimal medium loss and safe system operation. The flanges are machined in accordance with EN 1092-2 for body material group A, ensuring compatibility with existing installations. The face-to-face dimension complies with EN 558-1 Series 1, facilitating easy installation and integration with other system components.

The valve meets the requirements of the Pressure Equipment Directive 97/23/EC and carries CE marking for DN 32, confirming its safety and compliance with European standards. Design variant 08 features a steel stem, bonnet, and body ring—enhancing mechanical strength and resistance to damage. The PTFE bonnet seal ensures long-term tightness and minimizes leakage risk.
