Float valve DN40, FIG.274, construction 16: stem and mushroom – stainless steel, mushroom end – conical EPDM 274A040B16

The zFLO series float valve, model 274, is a reliable solution for liquid level control in piping systems. The DN40 valve, constructed from high-quality materials, ensures long-term, trouble-free operation. The design features a stem and disc made of stainless steel, with a conical EPDM disc end, guaranteeing resistance to corrosion and mechanical damage.

This valve is suitable for use with both hot and cold water, and its versatility allows installation in a wide range of systems—from residential to industrial applications. Flanges are cast in accordance with EN 1092-2, simplifying installation, while compliance with EN 558 Series 8 ensures compatibility with existing systems. Thanks to its high leakage class (A per EN 12266-1), it minimizes leakage risk and ensures safe operation.

Construction and materials:

• Body made of gray cast iron (EN-GJL-250) provides strength and resistance to mechanical loads.
• Stem and disc made of stainless steel (X20Cr13 / 1.4021) ensure corrosion resistance and long service life in contact with water.
• Conical EPDM disc end guarantees sealing and flexibility.
• Additional EPDM seals prevent leakage.
• Entire design is optimized to minimize maintenance requirements.

Application and specifications:

The DN40 float valve is designed for hot and cold water systems with a maximum operating pressure of 10 bar (PN 10). Its angular body (angled configuration) facilitates installation in confined spaces. Thanks to high-quality materials, the valve is environmentally safe and requires infrequent inspections. Compatibility with neutral fluids extends its application beyond standard water systems.

This valve is suitable for use in:

• Sanitary installations in residential and public buildings,
• Irrigation systems,
• Industrial processes requiring precise liquid level control,
• Industrial systems using water as a working medium.
