Shut-off valve zGLO Fig. 215C, DN25 PN16, ductile iron EN-GJS-400-18-LT, construction: 91, stem-to-disc connection – detachable – screw, stem, regulating disc, and body ring – stainless steel, with opening indicator 215C025C91

Isolation Valve – Reliable Flow Shut-off in Demanding Installations

This isolation valve, model ZGLO Fig. 215C, with nominal diameter DN25 and pressure rating PN16, is a robust solution for precise flow shut-off across diverse systems. Manufactured from high-quality ductile iron EN-GJS-400-18-LT, it ensures durability and excellent corrosion resistance. The design features a detachable stem-to-bonnet connection secured by a screw, with internal components (stem, regulating disc, and body ring) made from stainless steel, guaranteeing reliable operation even under harsh conditions. An opening indicator facilitates visual verification of the valve’s position.

Durability and Safety in Every Detail

This valve is engineered for long-term service and user safety. The body, cast from ductile iron, offers high mechanical strength and resistance to cracking. Stainless steel components provide superior corrosion resistance and minimize the risk of medium contamination. The valve complies with the Pressure Equipment Directive 97/23/EC and carries the CE marking for DN 32, confirming conformity with European safety standards. Testing and verification have been performed in accordance with EN 12266-1, ensuring high tightness (Class A). Flanges are machined per EN 1092-2 for body material group A, and the face-to-face dimension conforms to EN 558-1 Series 1 requirements.

Broad Application – From Residential to Heavy Industry

This valve is suitable for a wide range of installations:

• Hot, cold, and chilled water systems: Ideal for central heating, domestic hot water (DHW), and air conditioning systems.
• Steam systems: Performs reliably in industrial steam generation and distribution networks.
• Industrial processes: A dependable component in production systems requiring precise flow control.
• District heating and power generation: Suitable for boiler rooms, cogeneration plants, and other energy facilities.
