Ball cap - regulating, 2" FF

Product detailed description

This regulating ball cap is commonly used in industrial and commercial water systems where precise flow control is required. It is suitable for installation in heating, plumbing and irrigation systems, particularly in applications where the medium is water at elevated temperatures. The valve is designed for use in systems operating at nominal pressures up to PN30 at 100°C, and PN10 at 150°C. It is often found in building services, including HVAC systems and process water circuits, where reliable shut-off and flow regulation are essential.

Installers working in these environments will find this valve ideal for applications requiring a durable, corrosion-resistant solution. The internal thread connection ensures compatibility with standard piping systems, while the adjustable Kv value allows for accurate flow setting based on system requirements.

Installation and connection

This ball cap is equipped with an internal thread (FF) connection, which must be matched with the corresponding pipe thread. Before installation, ensure the system is depressurised and the valve is correctly oriented. The valve should be installed in a position that allows for easy access to the handle and adjustment. Common installation errors include incorrect thread orientation and failure to check the sealing surfaces for debris. Always verify that the valve is fully open before tightening the connections to prevent damage to the sealing components.

Compatibility and accessories

This ball cap is compatible with standard water systems using copper or steel piping with internal thread connections. It is designed for use in potable water systems and meets relevant standards for drinking water compatibility. No additional accessories are required for standard installation, though sealing tape or compound may be used on the threads to ensure a leak-free connection. Related products include other ball valves and fittings from the IVAR range.

Technical background for designers

The valve operates on a ball-and-seat principle, where the ball is rotated to control flow. The nickel-plated brass body (CW617N) provides resistance to corrosion and ensures long-term reliability in water systems. The absence of silicone in the sealing materials ensures compatibility with potable water standards. The adjustable Kv value allows for precise flow regulation, making it suitable for applications where system balancing is required. The valve's performance is influenced by the operating temperature and pressure, which must be within the specified limits to ensure optimal service life.

Service and operation

Routine maintenance is not required for this valve under normal operating conditions. However, it is recommended to periodically check for leaks and ensure the handle moves freely. If the valve becomes difficult to operate, it may indicate the need for cleaning or lubrication of the stem. The adjustable upchuck design allows for maintenance without full disassembly, facilitating quick service interventions.
