Ball cap IVAR.KK 51, 6/4" FF

Product detailed description

Water ball valves are essential components in heating and plumbing systems across residential, commercial, and industrial buildings. They provide secure shut-off for water lines during maintenance or emergencies. Installers commonly encounter these valves in central heating circuits, domestic hot and cold water systems, and in irrigation or pump systems. Proper selection and installation ensure system integrity and long-term performance.

The IVAR.KK 51 is intended for use in applications where controlled flow isolation is required. Its nickel-plated brass construction ensures resistance to corrosion and wear, while the lever handle allows for easy manual operation. The valve is certified for use with potable water and is designed for integration into systems with varying pressure and temperature conditions.

Technical parameters

Nominal pressure	PN 10
EAN	8016603067397
Weight	1.356 kg
Code	5125150112
Brand	IVAR

The nominal pressure rating of PN 10 indicates the valve's maximum allowable pressure at standard operating temperatures. This parameter is crucial for determining correct sizing and compatibility with existing system components. The valve maintains PN 10 at +150 °C and PN 30 at +100 °C, making it suitable for both high-temperature heating systems and standard water distribution networks.

Installation and connection

To install the IVAR.KK 51, first confirm that the system is depressurised and all connected components are compatible. The valve features internal thread connections in 6/4 inch FF, requiring matching male threads on adjacent fittings. Ensure the lever is aligned with the direction of flow for full open position and perpendicular for closed. Common errors include incorrect thread orientation, mismatched sizes, and failure to clean threads prior to assembly. Always apply a suitable sealing compound or thread tape to prevent leaks.

Compatibility and accessories

This valve is compatible with standard pipe systems using 6/4 inch FF connections. When integrating into a system, ensure that adjacent components such as pipe fittings, unions, or adapters are also rated for PN 10 and constructed from compatible materials. Additional items such as sealing tape or gaskets may be required to ensure leak-free operation. No specific related products are recommended for this model.

Technical background for designers

The IVAR.KK 51 operates via a rotating ball with a bore that aligns with the flow path when open and blocks it when closed. The ball is housed in a body made from nickel-plated brass CW617N, which provides good mechanical strength and resistance to corrosion. The absence of silicone ensures compatibility with potable water standards. The valve integrates into systems with internal thread connections and is suitable for both low- and medium-pressure applications. Long-term efficiency depends on proper installation, correct orientation, and regular inspection of the sealing surfaces and lever mechanism.

Service and operation

Routine checks should include visual inspection for signs of leakage, corrosion, or wear on the lever and body. Ensure the valve moves freely without resistance, indicating that the internal components are not seized. There are no specified service intervals for this model, but any irregularities in operation should prompt immediate investigation. The adjustable packing allows for minor adjustments to prevent leakage without complete disassembly.
