Float valve DN65, FIG.272, construction 16: stem and mushroom - stainless steel, mushroom end - EPDM tapered 272A065B16

Float Valve – Reliable Flow Shut-off

The float valve DN65, type 272, is a robust and proven design intended for automatic shut-off of fluid flow in cold and hot water systems, as well as in systems using neutral media. It performs reliably in both industrial applications and fire protection or district heating systems. Its construction based on durable materials ensures long-term, maintenance-free operation.

Design and Materials

The valve features a well-engineered design that ensures high reliability and minimal servicing requirements. Critical components such as the stem and mushroom are manufactured from stainless steel, providing excellent corrosion resistance and long-term performance. The mushroom is sealed with an EPDM gasket, ensuring tightness and compatibility with various media. The body is cast from gray iron EN GJL-250, guaranteeing high mechanical strength. Flanges are machined in accordance with EN 1092-2, and the face-to-face dimension complies with EN 558-1 Series 1, facilitating seamless integration into existing installations.

Advantages and Applications

This float valve stands out with a high leak-tightness rating of Class A (per EN 12266-1), minimizing leakage risks and ensuring safe operation. It is environmentally friendly and requires no maintenance—once installed, it operates reliably for extended periods. Control is achieved via a float connected by a linkage, enabling automatic opening and closing of the flow based on fluid level. This makes it ideal for:

• Automatic water level regulation in tanks
• Overfill protection
• Emergency flow shut-off systems
• Industrial installations requiring precise liquid level control

The valve is designed for operation at a maximum working pressure of 10 bar and temperatures up to +90°C. Its versatility enables application across a broad range of systems—from domestic water supply networks to advanced industrial processes. Installation is facilitated by PN10/16 flanges, simplifying integration with existing infrastructure.
