Float valve DN125, FIG.274, construction 16: stem and mushroom - stainless steel, mushroom end - tapered EPDM 274A125B16

Float Valve – Reliable Solution for Water Systems

The float valve FIG.274 is a component designed for automatic control of liquid flow, particularly in hot and cold water systems. The valve’s construction ensures a high level of tightness and maintenance-free operation, resulting in long-term, trouble-free performance. Made from corrosion-resistant materials, it guarantees durability even under demanding conditions.

This valve is suitable for use in industrial, residential, and public utility installations where precise liquid level control and protection against overflow are required. Its angled design simplifies installation and integration with existing systems.

Construction and Key Features

The float valve DN125 from the FIG.274 series features a robust design and high manufacturing quality. The valve flanges are machined in accordance with EN 1092-2, ensuring compatibility with most standard piping systems. The face-to-face dimension complies with EN 558 Series 8, enabling easy replacement of existing valves without requiring modifications to the installation.

Particularly important is Design No. 16, featuring a stem and float disc made of stainless steel, with a conical end on the float disc sealed with EPDM. This combination of materials ensures excellent tightness and resistance to aggressive media. The use of EPDM as the sealing material also guarantees environmental safety. The valve meets Class A tightness (per EN 12266-1), confirming its superior sealing performance.

• Durability: Internal components made of stainless steel enhance corrosion resistance and extend valve lifespan.
• Tightness: Class A tightness ensures minimal fluid loss and safe system operation.
• Compatibility: Flanges machined to EN 1092-2 standard simplify installation and integration with existing piping systems.
• Maintenance-Free: The valve design requires no regular servicing, reducing operational costs.
• Versatility: Suitable for use in hot and cold water systems as well as neutral liquids.

Technical Parameters and Applications

The DN125 float valve operates at a maximum working pressure of 10 bar and a nominal pressure rating of PN 10. It is designed for operation at temperatures up to 90°C, making it suitable for a wide range of thermal conditions. Thanks to its design, this valve performs excellently in systems requiring precise liquid level control, such as retention tanks, irrigation systems, and industrial installations.
