Check valve zGLO Fig. 215C, DN40 PN25, construction 42: loose mushroom without spring, stem – brass, mushroom and body ring – bronze. Body – ductile iron. 215C040D42

Check valve with backflow prevention – reliable protection for installations

This valve combines the functions of a check valve and a shut-off valve, providing dual protection for the system. It prevents reverse flow of the medium while simultaneously allowing complete closure of the flow—essential during servicing or maintenance. The valve’s design enables easy identification, featuring a cylindrical stem extension that simplifies operation.

The ZGLO Fig. 215C valve, with DN40 diameter and PN25 pressure rating, is a robust solution for demanding applications. Manufactured from ductile iron, it ensures high strength and corrosion resistance. The use of brass for the stem and bronze for the disc and body ring guarantees reliable sealing and long service life. The free-floating disc design without a spring is ideal for systems where minimizing the risk of automatic valve closure is critical.

Design and materials – the key to durability

The valve features a thoughtfully engineered construction using high-quality materials:

• Body: Ductile iron – provides high mechanical strength and pressure resistance.
• Stem: Brass – corrosion-resistant and ensures smooth valve operation.
• Disc and body ring: Bronze – creates a leak-tight seal, minimizing leakage risk.
• Connections: Flanged – enable easy installation and removal within the system.

This careful selection of materials ensures long service life and trouble-free operation even under harsh operating conditions. This valve is particularly recommended for industrial applications and water or heating systems where high reliability and corrosion resistance are essential.
