Shut-off valve zGLO Fig. 215C, DN PN16, ductile iron EN-GJS-400-18-LT, design: 41, shut-off and check, loose disc without spring, stem, disc and body ring – stainless steel 215C125C41

zGLO Shut-off Valve – Reliable Flow Control

The zGLO shut-off valve Fig. 215C is a robust and durable solution for precise flow control in a variety of installations. Manufactured from high-quality ductile iron EN-GJS-400-18-LT, it ensures long-term, trouble-free operation even under demanding conditions. The shut-off/check design, combined with a spring-free floating mushroom, guarantees effective flow isolation and prevents medium backflow. A key feature is the use of stainless steel for the stem, mushroom, and body ring—providing high resistance to corrosion and extended service life.

This valve performs excellently in both hot and cold water systems, as well as in steam systems, industrial processes, district heating, and power generation. Designed for nominal pressure PN 16, it complies with stringent safety standards and carries CE marking for diameters DN 32 and larger. Compliance with the Pressure Equipment Directive 97/23/EC ensures its reliability and safe operation.

Design and Application

The Fig. 215C valve stands out for its meticulous construction and thoughtful design. Flanges are machined in accordance with EN 1092-2 for body material group A, facilitating installation and ensuring joint tightness. Overall length conforms to EN 558-1 Series 1, enabling easy replacement of existing valves. High sealing performance (Class A per EN 12266-1) minimizes leakage risk and ensures optimal system efficiency.

• Body Material: Ductile iron EN-GJS-400-18-LT – guarantees mechanical strength and corrosion resistance.
• Nominal Diameter: DN 125 – suitable for medium-flow installations.
• Nominal Pressure: PN 16 – safe operation under standard working conditions.
• Construction: 41 – spring-free floating mushroom, stem, mushroom, and body ring made of stainless steel – ensures reliable flow shut-off and resistance to internal corrosion.
• Application: Hot and cold water systems, steam systems, industrial processes, district heating, and power generation.
