Check valve zGLO Fig. 215C, DN15 PN25, construction 32: spring-loaded loose mushroom, stem – brass, mushroom and shell body – bronze. Body – ductile iron. 215C015D32

The check and shut-off valve ZGLO Fig. 215C is a reliable solution for protecting installations against backflow of the medium, while also enabling complete flow shut-off. This is particularly critical in systems requiring protection against medium reversal, such as water, heating, or industrial process systems. The valve’s design combines the functions of a check valve and a shut-off valve, resulting in versatile application and space savings.

This valve features a robust construction: the body is made of ductile iron, ensuring high pressure resistance and corrosion protection. The disc and seat ring, manufactured from bronze, guarantee tightness and resistance to wear, while the stem made of brass ensures smooth operation of the mechanism. The design 32 – loose disc with spring – enables rapid and secure closure of flow, while minimizing the risk of mechanical damage.

The valve is equipped with flanged connections, simplifying installation and removal in existing systems. It is rated for a nominal pressure of PN25, making it suitable for medium- and high-pressure applications. Notably, this model is available in DN15 size, allowing seamless integration with various pipe diameters.

The valve stands out by combining shut-off and check valve functions, optimizing space and reducing the number of required components. The ductile iron body ensures resistance to high pressure and corrosion. Tightness is guaranteed by the bronze disc and seat ring, while flanged connections facilitate integration into existing systems. This valve is widely used in water, heating, and industrial installations requiring protection against backflow.

Check and shut-off valves Fig. 215C are commonly applied in:

• Central heating systems – protection of boilers and pumps against backflow of hot water.
• Water supply systems – prevention of contamination of potable water sources.
• Industrial processes – protection of equipment from damage caused by reversal of process media.
• Sanitary installations – protection against backflow of wastewater.
