Ball cap - regulating, 6/4" FF

Product detailed description

Regulating ball valves are essential components in the design and maintenance of water-based systems in residential, commercial and industrial buildings. These valves enable controlled flow regulation in pipelines transporting potable or non-potable water. Installers often encounter these valves in domestic hot water circuits, central heating systems and pump circuits. Precise flow control ensures efficient system operation and helps prevent issues such as overpressure or thermal shock.

The IVAR regulating ball valve is designed for applications requiring both isolation and flow modulation. It is commonly used in HVAC systems, where accurate control of fluid dynamics is necessary. The valve’s robust construction supports long-term reliability in environments subject to fluctuating temperatures and pressures.

Technical parameters

Nominal pressure	PN 30
EAN	8016603067489
Weight	1.453 kg
Code	3704015150
Brand	IVAR

The nominal pressure rating (PN 30) indicates the maximum allowable pressure at specified temperatures. This valve can operate under PN 30 conditions at up to 100°C, and under PN 10 conditions at up to 150°C. These ratings influence system design decisions, particularly in high-temperature applications such as heat exchangers or steam condensate return lines.

Installation and connection

To install the valve, ensure the pipeline is empty and depressurised. The valve has internal female threads (FF) for connecting to male-threaded pipe ends. Check that the thread engagement is fully seated and apply a suitable sealing compound. Align the valve body with the flow direction to avoid turbulence. A common mistake during installation is incorrect orientation, which can lead to uneven wear or leakage. Always verify the sealing integrity after tightening using a torque wrench calibrated to the manufacturer’s specifications.

Compatibility and accessories

This valve is compatible with standard water supply and distribution systems using threaded connections. It should be used in conjunction with mating fittings and pipe ends that match the internal thread specification. Additional accessories such as union nuts or sealing tapes may be required to ensure a leak-free installation. No alternative or related products are available for this model.

Technical background for designers

The valve operates via a rotating ball with a port that aligns with the flow path. The ball is encased in a body made from nickel-plated brass (CW617N), chosen for its corrosion resistance and mechanical strength. The absence of silicone in the sealing materials makes this valve suitable for potable water applications. The adjustable stem allows for fine-tuning of the flow coefficient (Kv), enabling precise control over hydraulic performance. System designers must consider the Kv value when calculating pipe diameters and pressure drops to maintain optimal system efficiency.

Service and operation

Routine inspection should include checking for leaks around the body and stem seals. Any signs of leakage may indicate a need to re-tighten the packing or replace worn components. The valve features a serviceable stem seal, which allows for maintenance without removing the entire unit from the pipeline. No specific service intervals are provided, but regular visual inspections are recommended to ensure continued reliable operation.
