Check-and-shut-off valve – reliable protection for installations

The check-and-shut-off valve zGLO Fig. 215C, in size DN50 and pressure class PN25, combines the functions of backflow prevention and complete shut-off of medium flow. The valve’s design ensures effective protection of the system, while its versatility makes it suitable for a wide range of applications.

This valve is constructed from high-quality materials: the body is made of ductile iron, providing strength and corrosion resistance, while internal components—including a brass stem and bronze disc—ensure tightness and long-term reliability. Particularly important is the use of a spring-free floating disc, which ensures smooth operation and minimizes the risk of damage.

Construction and application

Check-and-shut-off valves differ from standard shut-off valves by the presence of a cylindrical recess on the stem, facilitating installation and maintenance. This model features flanged connections, ensuring a leak-proof and stable connection to the pipeline. As a result, the valve is ideal for systems requiring both backflow protection and the ability to fully isolate the medium.

This valve is especially recommended for applications demanding high reliability and resistance to operating conditions. The ductile iron body (EN-GJS-400-18-LT 5.3103) guarantees mechanical strength and resistance to chemical corrosion. The brass stem ensures smooth valve operation, while the bronze disc and seat ring provide superior sealing.
