Ball cap IVAR.KK 51, 5/4" FF

Product detailed description

Water ball valves are essential components in heating and plumbing systems where secure and leak-free shut-off is required. The IVAR.KK 51 is commonly used in residential and commercial buildings for isolating sections of water supply lines during maintenance or repairs. Installers working on central heating systems, hot and cold water distribution, and sanitation systems will find this valve suitable for applications involving clean water. It is particularly useful in systems where access for maintenance is limited, as the compact design allows for installation in tight spaces.

The valve is designed to operate efficiently under varying temperature conditions, ensuring consistent performance in both domestic and industrial environments. It is commonly integrated into systems such as underfloor heating, boiler circuits, and hot water storage units. The internal thread FF connection ensures compatibility with standard pipe fittings and reduces the risk of misalignment during installation.

Technical parameters

Installation and connection

Installation of the IVAR.KK 51 requires precise alignment of the internal thread FF connections on both ends. The valve should be positioned in a way that allows for easy access to the lever handle for future operation. Prior to tightening, ensure that the threads are free of debris and coated with a suitable sealing compound to prevent leaks. A common mistake during installation is over-tightening the fittings, which can damage the sealing surfaces or cause deformation of the valve body. Always follow the manufacturer’s torque recommendations when securing the connections.

Compatibility and accessories

This valve is compatible with standard pipe systems using internal thread FF connections. It is intended for use with clean water and is certified for potable water applications. When installing, ensure that the system pressure and temperature conditions align with the valve’s specifications. Additional accessories such as wrenches for tightening the connections and sealing tape or compound may be required for a secure fit. No related products are recommended for this model.

Technical background for designers

The IVAR.KK 51 operates using a spherical closure mechanism that rotates within a housing to control the flow of water. The nickel-plated brass CW617N construction provides resistance to corrosion and wear, making it suitable for long-term use in water systems. The absence of silicone in the sealing components ensures compatibility with potable water standards and reduces the risk of chemical leaching. Integration into a system requires consideration of the flow rate, pressure drop across the valve, and the need for regular maintenance checks to ensure continued performance.

Service and operation

Regular inspection of the valve’s connections and operating lever is recommended to detect signs of wear or leakage. During operation, the lever should move smoothly without resistance. If stiffness occurs, disassemble the valve and inspect the internal components for debris or corrosion. No specific service intervals are provided in the technical documentation; however, any visible damage or operational issues should prompt immediate replacement.
