Shut-off and control valve – reliable flow control

This shut-off and control valve, model ZGLO Fig. 215C, with a nominal diameter DN200 and nominal pressure PN25, is a robust solution for precise flow regulation in industrial and technical systems. Manufactured from high-quality materials, it ensures long-term, trouble-free operation. The design featuring a threaded connection between the stem and the mushroom simplifies servicing and component replacement.

Throttling mushroom valves, such as this model, are widely used for regulating the flow of liquids and gases. Selecting the appropriate construction—particularly the material of the mushroom and stem—is critical to ensuring optimal performance and durability under specific operating conditions.

Construction and materials

The valve body is made of ductile iron, guaranteeing high mechanical strength and corrosion resistance. The stem is manufactured from brass, while the control mushroom and seat ring are made of bronze, ensuring smooth flow regulation and resistance to wear. Additionally, the valve is equipped with an opening indicator, enabling quick visual inspection of the valve position. Flanged connections facilitate installation and removal in existing systems.

The valve features a body made of ductile iron EN-GJS-400-18-LT 5.3103 (ex JS1025), a stem made of brass, and a control mushroom and seat ring made of bronze.

Applications and special features

This valve is suitable for a wide range of systems requiring precise flow regulation of the medium. Thanks to its design, it performs exceptionally well in water, heating, and industrial installations. The detachable stem-to-mushroom connection simplifies maintenance and repairs, minimizing system downtime. Please note that the manufacturer reserves the right to make design changes—always verify the current specification prior to installation.
