Shut-off valve GLO Fig. 215 DN100 PN16, gray cast iron EN-GJL-250, construction: 71, stem-to-bonnet connection – detachable – screw, stem, regulating disc, and body ring – stainless steel, without opening indicator 215A100C71

The ZGLO Fig. 215 gate valve is a reliable solution for precise flow shut-off in diverse installations. Manufactured from gray cast iron EN-GJL-250, this model with nominal diameter DN100 and nominal pressure PN16 performs excellently in both water and steam systems. The design features a detachable stem-to-bonnet connection secured by a screw, while internal components are made of stainless steel, ensuring long-term, trouble-free operation.

Construction and Application

This valve is widely used in hot, cold, and cooling water systems, as well as in steam systems, industrial processes, district heating, and power generation. Its versatility stems from a robust construction and high corrosion resistance. Construction code 71 – detachable stem-to-bonnet connection via screw, stem, control disc, and body ring made of stainless steel – ensures reliability and easy maintenance. The absence of an opening indicator simplifies the design and minimizes failure risk. The valve complies with the Pressure Equipment Directive 97/23/EC and carries CE marking for DN 32.
