Gate valve GLO Fig. 215 DN250 PN16, gray cast iron EN-GJL-250, design: 41, gate-check, loose gate without spring, stem, gate and body ring – stainless steel 215A250C41

Shut-off Valve – Reliable Flow Stoppage in Diverse Installations

The zGLO Fig. 215 shut-off valve is a proven industrial valve designed for effective stoppage of media flow across a wide range of applications. Its construction, based on a gray iron body and stainless steel internal components, ensures durability and corrosion resistance even under demanding conditions. This model, with a nominal diameter DN250 and pressure class PN16, performs excellently in both water and steam systems.

Construction and Materials – Key to Long Service Life

The valve’s body is manufactured from gray iron EN-GJL-250, providing high mechanical strength and resistance to thermal stresses. Critical internal components — the stem, disc, and seat ring — are made from stainless steel, minimizing corrosion risk and ensuring smooth, long-term operation. The designation "41" indicates a non-spring-loaded shut-off valve, enhancing reliability and simplifying the design. Additionally, the valve features a loose disc, facilitating easy maintenance and replacement when needed.

Broad Range of Applications – From Industry to District Heating

The zGLO Fig. 215 valve is suitable for numerous industrial and building installations:

• Hot and cold water systems: Reliable stoppage of media flow in water supply networks.
• Steam systems: Safe operation in heating systems and industrial processes utilizing steam.
• Industrial technologies: Stoppage of various media in production processes.
• District heating: Control of heat flow in central heating systems.
• Power generation: Use in energy installations requiring highly reliable valves.

The valve complies with the Pressure Equipment Directive 97/23/EC and bears the CE marking for DN≥32, confirming its safety and conformity with European standards. Technical data for this valve are integrated into leading calculation software libraries (Instal-therm, Instal-san, Audytor C.O. 3.8, Audytor H2O 1.5), simplifying professional system design. Testing and inspections have been conducted in accordance with EN 12266-1, guaranteeing high quality and tightness (Class A per EN 12266-1). Flanges are machined in accordance with EN 1092-2 for body material group A, and the face-to-face dimension complies with EN 558-1 Series 1.
