Ball cap IVAR.KK 51, 3/4" FF

Product detailed description

Water ball valves are essential components in heating and plumbing systems, particularly in residential and commercial buildings. They are commonly used in domestic hot and cold water supply lines, as well as in central heating circuits. Installers frequently encounter these valves during system maintenance, pipe replacement or new installations. The IVAR.KK 51 model is specifically designed for use in systems requiring a durable and reliable shut-off solution with minimal pressure drop.

When working with this valve, technicians should consider the operating conditions of the system, including temperature and pressure fluctuations. The internal thread connection ensures compatibility with standard piping systems, while the lever handle allows for easy manual operation. The valve is suitable for use in both new construction and renovation projects, where a compact and efficient shut-off device is required.

Technical parameters

Installation and connection

The IVAR.KK 51 water ball valve is equipped with an internal thread connection (FF) in 3/4 inch size, making it compatible with standard copper or steel piping systems. During installation, it is important to ensure that the threads are clean and free from debris to prevent leaks. Apply a suitable sealing compound or PTFE tape to the male thread before tightening the connection. The valve should be installed in a fully open position to avoid damaging the sealing surface during tightening.

Common installation errors include over-tightening the valve, which can deform the body or damage the sealing mechanism, and incorrect orientation of the lever handle. The lever should be aligned in the direction of the flow for easier operation. Always verify the system pressure and temperature before commissioning to ensure the valve operates within its rated specifications.

Compatibility and accessories

This water ball valve is designed to integrate with standard plumbing and heating systems that use internal thread connections. It is suitable for use with copper, steel and plastic pipes, provided the connection is properly prepared and sealed. No additional accessories are required for basic installation. For systems requiring remote operation or automated control, separate actuators would need to be specified and ordered separately.

Technical background for designers

The IVAR.KK 51 operates on the principle of a rotating ball with a bore that aligns or blocks the flow path. The ball is seated between two metal or elastomeric seals, 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 mechanical strength. This makes it suitable for use in potable water systems and environments where chemical exposure is a concern.

The absence of silicone in the sealing components ensures compatibility with certain water treatment chemicals and reduces the risk of degradation over time. The valve integrates seamlessly into heating and plumbing circuits, with its compact design allowing for installation in tight spaces. The service life and efficiency of the valve depend on the quality of the installation, the cleanliness of the system and the operating conditions such as pressure and temperature fluctuations.

Service and operation

During regular system checks, technicians should inspect the valve for signs of leakage, corrosion or mechanical wear. The lever handle should move freely without resistance, indicating that the internal mechanism is functioning correctly. If a leak is detected at the connection, reseal the threads using appropriate methods and ensure the valve is tightened to the manufacturer’s recommended torque. The valve does not require scheduled maintenance beyond these periodic inspections.

Frequently asked questions

Can the IVAR.KK 51 be used in potable water systems?
Yes, the valve is certified for potable water applications and constructed from materials that meet relevant standards for drinking water compatibility.

Is the valve suitable for high-temperature systems?
It is rated for operation at up to +150 °C with a nominal pressure of PN 10, making it suitable for domestic hot water and heating systems.

Can the valve be used with plastic piping?
Yes, provided the internal thread connection is compatible with the plastic pipe fitting and the joint is properly sealed.

What is the recommended method for sealing the thread?
A suitable sealing compound or PTFE tape should be applied to the male thread before tightening the connection to ensure a leak-free seal.
