Ball cap IVAR.KK 51, 2 1/2" FF

Product detailed description

Ball valves are essential components in heating and plumbing systems, used to control the flow of water in various applications. The IVAR.KK 51 model is commonly installed in residential and commercial buildings, particularly in systems requiring reliable shut-off at elevated temperatures. Installers typically encounter these valves in central heating systems, hot water distribution lines, and industrial water circuits. The valve’s design ensures a secure and durable connection, suitable for environments where thermal expansion and pressure fluctuations are common.

When selecting and sizing a ball valve, it is important to consider the operating conditions, including temperature and pressure. The valve must be compatible with the system’s media and flow requirements. The IVAR.KK 51 is designed for use with water and is certified for potable water applications, making it suitable for both heating and sanitary systems. The FF (female-female) connection ensures a secure fit with threaded pipe ends, and the lever handle allows for easy manual operation.

Technical parameters

Installation and connection

Installation of the IVAR.KK 51 ball valve requires careful preparation to ensure a leak-free and secure connection. The valve is equipped with internal female threads (FF), which must be matched with the corresponding pipe ends. Prior to installation, the threads should be cleaned and inspected for damage. A suitable thread sealant or PTFE tape should be applied to the threads to prevent leakage. The lever handle should be aligned with the flow direction for full opening or perpendicular for closure. Common installation mistakes include over-tightening the connections, which can damage the threads, and failing to check the alignment of the valve within the system.

Compatibility and accessories

The IVAR.KK 51 is compatible with standard threaded pipe systems and is typically used in conjunction with other water control components such as check valves, pressure regulators, and flow meters. For complete system integration, it may be necessary to order additional components such as pipe fittings, sealing materials, and mounting brackets. The valve is designed for use in systems operating with water and is suitable for both heating and sanitary applications. No specific accessories are required for installation, but it is recommended to verify the compatibility of all components with the system’s operating conditions.

Technical background for designers

The IVAR.KK 51 operates on a simple yet effective principle: a rotating ball with a bore that aligns or blocks the flow path. The ball is seated between two sealing surfaces, ensuring a tight shut-off when closed. The valve body is constructed from nickel-plated brass CW617N, a material known for its corrosion resistance and durability in water systems. The absence of silicone in the sealing mechanism ensures compliance with potable water standards. The valve integrates seamlessly into heating and plumbing systems, where it provides reliable flow control and minimal pressure drop. The service life and efficiency of the valve are influenced by factors such as operating temperature, media purity, and the frequency of operation.

Service and operation

Regular inspection and maintenance are essential to ensure the continued performance of the IVAR.KK 51 ball valve. Installers should periodically check the valve for signs of wear, leakage, or corrosion, particularly at the connection points and sealing surfaces. The lever handle should be tested for smooth operation, and any resistance or sticking should be addressed promptly. The valve does not require scheduled service intervals, but it is recommended to inspect it during routine system maintenance. If leakage is detected, the connections should be re-tightened or the sealing material replaced as necessary.

Frequently asked questions
